Jolie Ginsburg — Owner

Jolie Ginsburg is co-owner and CEO of Incredible Adventures. She started guiding for Incredible Adventures in 2000 soon after moving to San Francisco and 2 months later bought the company with her business partner Brian Deninger. She used to be on the road several days a week; now Jolie just does the occasional trip, but still likes that she can travel and interact with people while working. She grew up mainly in Houston and Pittsburgh, the oldest of a younger sister and brother, and has traveled to all 50 states and to every continent except Antarctica.

Jolie is an active member and coordinator of two local biofuel collectives, raising awareness of alternative fuels, making it more accessible and advocating its use by public transportation and other large fleets. Her favorite van is #3 because it’s the first van to be run on Biodiesel. She strives to be self-sustainable and environmentally conscious, both in her personal life and in her business operation. Jolie loves almost all outdoor activities – hiking, climbing, biking, anything that ends with “-ing.” Her favorite wine is beer, and her favorite foods are Japanese and Mexican. She’s been kissed by a black bear in Yosemite, and has spotted a few bobcats. Cloud’s Rest is Jolie’s favorite Yosemite hike because it’s like a slide that she’s tempted to ride down.

Incredible Adventures Owners Brian Deninger and Jolie Ginsburg

Brian Deninger — President

Brian Deninger is co-owner and President of Incredible Adventures and is responsible for marketing and business development. Brian moved to San Francisco in 1999, worked temp jobs and wore a suit to his job at Citibank until buying the company with his business partner Jolie Ginsburg. He grew up in Fontana, about 45 minutes east of Los Angeles. His love for the outdoors started as a teenager when he and good friend Damon almost froze to death in 14-degree winter weather, with tennis shoes and a living room pup tent. They survived, and Brian went on to lead backpacking trips at UC Santa Barbara. He still enjoys leading trips occasionally, especially the opportunity to interact with people from different walks of life. He appreciates being involved in his community and providing jobs to some pretty amazing people. He loves all Incredible Adventures vans equally.

Brian is on the board of and member of the San Francisco Biodiesel Collective. His hobbies include snowboarding, surfing, rock climbing, backpacking, camping, whitewater kayaking, traveling, and lately has been cultivating a taste for fine wine (especially Zinfandel and Cabernet Sauvignon). His favorite music is alternative rock, and his favorite food, true to his SoCal roots, is Mexican.

Brian’s favorite Yosemite hike is the Hetch Hetchy Grand Canyon because of its amazing camps, few people, wonderful waterfalls, towering cliffs, and an amazing diversity in wildlife. His best wildlife sighting was a coyote chasing a deer – made him think of the trials of life. Homewood is Brian’s favorite winery in Sonoma because it’s his Cheers! He also really likes Ceja in Napa, a winery owned by former vineyard workers. One of his top spots in the city is the weekend drum circle in Golden Gate Park.

Brian has made numerous cross-country road trips and has traveled the world, including 4 months in China, and Korea, Japan, Vietnam, Egypt, Costa Rica, Mexico, and several European countries.

Brian is the youngest of three. His older sister Kellie Flowers is an amazing person, mother, and sister, and his older brother Mike Deninger is a bit crazy but always makes him laugh.


 JD Boyle — General Manager

Incredible Adventures General Manager, JD Boyle, on his sailboatJD found his way to the mountains of Steamboat Springs, Colorado from the hills of Kentucky in 1995. He quickly began to expand his knowledge and love of the wilderness as a white water rafting guide, a rock climber and an avid backpacker. Moving south to continue his education at Fort Lewis College in Durango turned out to be a perfect fit as it was situated near all of the outdoor activities he loved and the study of the surrounding geology was absolutely enthralling.

In the spring of 2000, after guiding raft trips for four years, JD began his career as a North American Tour Leader spending most of that decade guiding people from all over the world to the highlights of the USA, Canada and Mexico as well as Guatemala and Belize.

After several years on the road as a guide, JD took a more serious role in transportation working with Con-Way Truckload and became a Certified Director of Safety through the North American Transportation Management Institute. He served as an Operations Assistant Manager, then the Fleet Safety and Compliance Manager and Head of Department for an international tourism organization.

The sense of adventure and care for the environment is still strong for JD, as he pedals his Surly LHT to work most days and with the recent purchase of a 37 foot sailboat, he’ll often be found exploring the San Francisco Bay under the power of the wind and, of course, the occasional use of some of that sweet recycled cooking oil from Dogpatch Biofuels when he has to crank up the diesel.


 Jessa Venegas — Sales & Marketing Director

Jessa at Pescadero State Beach with Seaweed on her headJessa joined Incredible Adventures in 2010, initially working in reception and operations, and is now managing the Sales & Marketing for the company. Always a California girl, Jessa moved to San Francisco from her native home of Santa Cruz in 2004 to pursue a career in fine art. Though her illustrious career as a painter never quite materialized, she still enjoys creating visual art in many forms. She also sings and plays the ukulele.

Jessa loves the idea of making people’s vacations wonderful, and enjoys being in a position to help people find the perfect way to experience a new (or familiar) destination. When she travels, she likes to get off the beaten path and find something new and un-tourist-y. If she can learn a new recipe, a new song, or wind up totally lost somewhere, she’s happy.

Never really a city girl, Jessa’s favorite places in San Francisco are the green parts. You’ll often find her running at Stow Lake in Golden Gate Park, or hiking the trails at Land’s End (arguably the most beautiful view of the Golden Gate Bridge and the ocean). Her favorite wine is Petite Syrah or Zinfandel, and her favorite beer is, of course, Anchor Steam. Her current favorite restaurants in SF are Nopalito (awesome Mexican food), and Plow (hands-down the BEST fried potatoes in SF, and dangerously close to the office).

Jessa spends most of her free time in the mountains foraging wild edibles, or in the kitchen cooking them. Having grown up in Northern/coastal California, she can tell you pretty much anything about the wildlife in the area (especially if it’s delicious). Believe it or not, she’s got a giant garden, a flock of backyard chickens, and 2 hives of bees right here in the city. Eventually she’d like to keep goats as well. />


Damian Boudreau — IA Operations Manager

Damian Boudreau, our Incredible Adventures Operations Manager

Hailing from the beautiful Pacific Northwest, Damian has always been an avid traveler and adrenaline junkie, so pursuing a career in the adventure travel industry seemed like a great way to blend those two passions.

After graduating from the University of Washington, Damian headed to a small coastal town in Oregon to write copy for a small town newspaper. The stress, deadlines, life in a cubicle, coupled with the lack of sunshine and fresh air, soon sent him looking for a new adventure. In 2008, he sold everything he owned and went overseas to teach English in Busan, South Korea. In 2010, he moved back to the States and started working as a tour leader for Trek America.  He loved the feeling of taking folks from all over the world on amazing, adventure-filled trips all across the US and Canada.

After putting in four years on the road, he moved into the management side of the travel industry as an operations assistant with PEAK Adventure Travel. He recently moved to the Bay Area and loves the fact that he can swim in the Pacific, snowboard in the Sierras and dance in a San Francisco club all in one day!




Dan Katzen — Financial Controller and Business Development/Group Sales

Dan Katzman, Overland Operations ManagerDespite growing up in the Pacific Northwest and being introduced to the outdoors at an early age by his parents, Dan’s real appreciation for nature and travel didn’t develop until after college. As an accountant stuck working in cubicles (and one time in an actual closet), he found that the outdoors provided a much-needed escape from the corporate world. In the summer of 2012 he decided to shake things up: he quit his job, bought a truck, and embarked on an adventure-filled road trip from California to Alaska. It was during this trip that Dan realized he had the freedom to do and be whatever he wanted.

Since that life changing revelation, Dan has been steadily seeking new experiences and pushing himself to find a meaningful way to live. He spent two summers as a tour guide, giving foreign passengers a chance to enjoy the type of road trips his parents took him on as a kid, as well as the trips he took in college with his friends. He believes that travel has an incredible power to change lives, and is excited and humbled to have a career that revolves around providing that experience.

In travel and in life, balance is important to him and when he is not busy making sure every passenger has an authentic, life changing experience, you can find him on his bike exploring San Francisco, rock climbing, rolling out his yoga mat, or checking out new music at local venues.



Anne Mayovsky — Business Development Manager

Our Fleet Manager, Anne Mayovsky, changing a tire. As a unicorn. Because reasons.Growing up in Seattle, WA, Anne Mayovsky developed a deep love for the mountains wild, houseboat life, and IPA. She began her wanderlust in college where she hopped from Missoula, Iceland, and finally to Bellingham to earn her undergrad in Exercise Science. After college, instead of finding a career or going back for a master’s Anne spent a year traveling through New Zealand, cycling the Lewis and Clark Trail, and finally moving to Southeast Alaska to drive coaches for the cruise ships.

After a summer in Alaska, she then took up a job as a guide leading North America small group adventure trips for four years, culminating in another incredible season in Alaska.

And thus cemented the love of anything to do with adventure, travel, exploring, and community. Anne is excited to be returning to the tourism/travel industry, and moving to San Francisco with her bikes for every terrain, small library, and boxes of costumes!



Samantha Less — Accounts Administrator

Samantha Less, our Accounts Administrator here at Incredible Adventures, loves backpacking and being in the wildernessSam’s love of all things travel and outdoorsy started at a young age with growing up between Florida, Colorado, and Arkansas. Always an explorer, there was an early appreciation for nature through many family camping trips across the States, and a love of travel through trips to Europe to visit the Dutch side of the family.

After graduating from high school in Arkansas, and earning her college degree in Environmental Science in Colorado, it was off to explore California which would become her adopted home state, and a state still being avidly explored to this day, 13 years later.

After college, Sam worked in environmental education and sustainability outreach for about 9 years around California (including 5 years in the Bay Area) before switching gears to do some traveling. After backpacking around South America for 6 months and then volunteering on an organic farm for 4 months, Sam returned to San Francisco and started working for Incredible Adventures in early 2012.

She started off in customer service and reservations, but then discovered a passion for reconciling receipts and is most happy preparing invoices, resolving discrepancies, and yes, tackling spreadsheets in the role of the Accounts Administrator.

When not at work, Sam loves backpacking into the wilderness, hiking on local Bay Area trails, exploring new places, training in her martial arts practice, blog writing, and watching women’s soccer games.


Josh Garber — Recruiting & Training Manager

Don't mess with our G Adventures Operations Manager, Josh Garber.Josh was born and raised just outside of Philadelphia, where everyone has their own favorite cheesesteak joint and next year is always the year that the beloved Eagles will bring home the Vince Lombardi Trophy. Instead of starting a career or getting a job after attending the University of Pittsburgh, Josh got lost in Europe with his childhood friends and this ignited a passion for travel that has never dwindled.

He paid off his credit cards by playing in several jazz trios on cruise ships that took him to all the corners of the planet accessible by sea. Once he had explored enough port city markets, consumed plenty of beachside margaritas in the Caribbean, and haggled with nearly every taxi driver to get him as far from the ship as possible while returning in time for departure, Josh decided to look for a new adventure closer to home. Josh put down his bass and became a North American tour guide where he escorted travelers to dozens of cities and national parks, hundreds of restaurants and dive bars, handfuls of upscale dining establishments and art museums while fueling that passion for travel and cultivating his desire to share that passion with as many travelers as possible.

Josh is very excited to be working with such an eclectic crew that cares as much about their own travels as they do about enriching the lives of their fellow travelers, the places we visit and the people we meet on the road.



Vince Harrington — Fleet Manager 
vince on a camel=Vince has been an outdoor adventure seeker and traveler for as long as he can remember. Beginning most recreational activities including backpacking and skiing at only 4 years of age, he never turns down an opportunity to be outside.

His most notable adventure took him to the Gobi Desert of Mongolia where he traveled via camel for 2 months.

He has hiked the John Muir Trail from Yosemite Valley to the top of Mt Whitney as well as traveled the world on Semester at Sea covering over 10 countries in 100 days.

Vince has made San Francisco home for over 7 years. He’s currently hoping to learn to become a competent beginner kite surfer this season although he seems to be allergic to cold salt water. />



Leslie Halward — Customer Service Representative

Our Incredible Adventures CSR LeslieLeslie grew up mainly in Watsonville and Gilroy. Although she doesn’t claim to be a super outdoorsy type of person, she love nature; hiking and photography are her favorite ways spend some time in nature. Leslie moved to San Francisco almost 2 years ago and spent way more time being outdoors/enjoying hikes and historic landmarks in a city than she did back home in a town with forests and hills.

She likes being around people who are really happy about helping others experience nature and like venturing out all over the place to see as much as they can. Our customer’s journeys seem really exciting and interesting and make Leslie want to get out there too more and more.




Brendol Swygert — Customer Service Representative
Our Incredible Adventures CSR Brendol Swygert

Brendol grew up in the Bay Area. After graduating from Albany High School, she decided to try her hand in photography at the Academy of Arts University in San Francisco. Although photography didn’t turn out to be her true calling, she does enjoy snapping photos every now and again in her free time.

She is also quite the movie buff! She loves going to the movies in her spare time.

Even though she would have never previously regarded herself as much of a nature girl, working at Incredible Adventures has opened her eyes to the true beauty that is nature itself.

Having yet to travel outside of the US, she hopes to do so one day to see what else the world has to offer!






Glen Chow

Mitch loves getting to know his passengers and making sure that they have an “incredible adventure” that they will long remember as the highlight of their visit to San Francisco!!!


Emily Bresko — Guide

Growing up on Long Island, New York, Emily never felt at home on the East Coast. Yearning for mountains and open spaces, she headed out west to Colorado, where she earned her degree in Environmental Studies. After indulging in all the sunshine, hiking and craft beer that Boulder had to offer, she sought out jobs that would pay her to play outside and explore new places.

She’s worked as an outdoor educator/naturalist in Rhode Island and a trail crew leader back in the mountains of Colorado. She lived on a small permaculture farm in Panama for a year, where she spent her days leading hikes through the jungle.

In the summer of 2016, she traded in her machete for trekking poles and hiked from Mexico to Canada on the Pacific Crest Trail. Now, she’s excited to rediscover California and share her love of adventure with other travelers as a guide for Incredible Adventures!

When she’s not guiding for IA, you can find her hiking, backpacking, savoring unique foods, getting too competitive playing board games, or planning her next adventure abroad.



Zachary MacDonald — Guide

Zach was born in the Bay Area and raised in the great state of Idaho. Throughout his childhood, Zach was fascinated by the plants and animals around him. Every spare moment he had was spent discovering all the beauty and diversity of Idaho. He attended the University of Idaho where he continued to explore the outdoors through wildlife, ecology, and conservation classes that eventually led him to a Bachelors degree in Biology.
After college, Zach travelled north to Alaska where he spent four years rehabilitating and training Bald Eagles and other birds of prey. After a short season as a deck hand, he moved back to the lower 48 and began working as a guide in Jackson Hole, WY where he took guests on dog sledding expeditions. He spent three years raising, training and loving on 180 Alaskan Huskies, while also teaching, guiding and protecting people from all over the world in a harsh backcountry environment. Through this experience he knew he had found his passion – enabling others to experience, learn about and come to love the outdoors and all it has to offer.
From Wyoming, Zach left on a 15,000 mile year-long road trip around the U.S. exploring all the well-known as well as hidden treasures in our country. When Zach isn’t guiding, you’ll find him kayaking in the everglades, fishing in Yellowstone, or seeing a Broadway show in New York City.

Samantha Brogdon  — Guide

Although she was born in a small Californian town, Sam has had an adventurous life from the start. Shortly after she was born her family moved to Alaska for her father’s job as a helicopter pilot. At the age of 10 her family sold everything they owned, drove from Homer, Alaska to St. Augustine, Florida in a motor-home and bought a sailboat. The next 5 years were spent sailing throughout the Caribbean and South America, which is where her love of travel was cultivated.

The family eventually moved to Washington state, and Sam began pursing adventurous jobs, from Yellowstone National Park to Spain. After backpacking around South America, Africa and Europe, she settled down in Spain for about a year and began teaching English. She eventually returned to the US and began working as a tour leader running cross-country road trips in 2016, driving over 25,000 miles and visiting 22 states in one summer.

Sarah McLear  — Guide

Sarah grew up in the flat Midwest but has always been drawn to the mountains.

 While studying at the University of Evansville, Sarah made the life-changing decision to study abroad for a semester in the UK. Using England as home base, she took advantage of those budget airlines and experienced everything from hiking through the Swiss Alps to cruising under the Northern Lights in Iceland.

 After graduating with a B.S. in Visual Communications and Design, Sarah decided that the office life just wasn’t for her. She then went on to work as an outdoor educator on the east coast teaching climbing, paddling, caving, and outdoor living skills.

 Sarah has most recently returned from spending a couple of months travelling through Australia, where she completed her open water diver certification, road tripped to several national parks, and worked as a farmhand in Tasmania. Next on her list is hiking in South America!

 She can’t wait to start sharing her love of the outdoors as a part of the Incredible Adventures team!



Rourke Benson  — Guide

As a South Bay Area native I grew up in the Santa Cruz Mtns catching salamanders and exploring the Redwoods in my back yard before developing a lifelong passion for the the ocean thru surfing.  Since then most free moments have been spent scouring the coast of California in search of cold water thrills.  Forever amazed with nature, I’m most inspired and happy when outdoors or traveling and learning new things.  The best year of my life was most definitely a year spent living out of a backpack in South America wandering around the Andes learning Spanish along the way.

At one time I had a more normal career in construction management but opted for one where I could learn and teach for a living. The last 3 years I’ve spent learning to work with reptiles and amphibians with a local outdoor ed group which brings animals from all over the world into SF classrooms.  10 ft Burmese Python named Blondie is always the favorite but my personal favorites are Tree Frog Fred and Speedy the Gopher Snake.  In my free time you will still find me surfing but also hiking the many gems just south of San Francisco.  Favorite thing about the city itself….its tacos!  But a few other things as well!


More bios to come!
