Jeep Jamborees are off-road adventure weekends that bring together the outdoors, down-to-earth people, and their Jeep 4x4s. These off-road treks have a long tradition dating back to 1953 when 4×4 pioneer Mark A. Smith organized the first-ever Jeep Jamboree and voyaged across the Sierra Nevada Mountains by way of the old Rubicon Trail. In 1954, Willys Motors — then manufacturer of Jeep vehicles became involved with the adventure, and Jeep Jamborees have been an off-road tradition ever since.
Off-Road Hall of Fame and the Explorers Club member, Mark A. Smith also led the 1978-79 “Expedicion de las Americas” — a 20,000-mile odyssey from the bottom of South America to the top of North America, crossing the infamous Darien Gap — and headed the 1987 Camel Trophy expedition in Madagascar. After founding Jeep Jamboree USA in 1982, Mark became a Jeep brand consultant and has conducted intensive training for the U.S. Army Special Forces and law-enforcement agencies.
Mark’s passing in 2014 was a loss felt deeply by the off-roading community worldwide, and he was honored with tributes both locally and even from the corporate headquarters of the Jeep brand itself. His legacy, however, is carried on by his beloved wife Irene, still an active member of the board of directors; his daughter Jill who recently moved into a more philanthropic role to fulfill the families long time commitment to causes close to their hearts. A visitor to six of the seven continents, Jill regularly continues her travels to the planet’s most remote regions, most often performing volunteer and service work for humanitarian and animal conservation organizations. President and CEO Pearse Umlauf, who has run the day-to-day operations for 8 years and worked side-by-side with the Smith family since day one to ensure every part of Mark’s vision was fulfilled. Umlauf at the helm of the operation is committed to not only seeing Mark’s vision for the off-roading community fulfilled in every event they do, but he is devoted to a business that is family run and continues to seize opportunities for growth and expansion that align with the company’s core values.
President & CEO
Pearse Umlauf has been an integral part of Jeep Jamboree USA for more than 19 years, currently as President and CEO, overseeing the business and day-to-day operations of more than 700 staff and 50+ annual events domestic and internationally.

He oversaw the construction of the Quantico Marine Base Severe Off-Road Track, and vehicle testing on the Rubicon Trail aiding in product development for Jeep products for the past 13 years. Most notably in the past couple of years, Pearse led the JJUSA team that spent 45-days in Brazil installing a permanent off-road test/demonstration course for Jeep’s South American plant in Pernambuco.
In addition to the day-to-day operations, Pearse oversees the development of a worldwide database of trails around the world and traveled to some of the most remote off-roading areas in Kenya, Tanzania, Morocco, India, Cambodia, Vietnam, Argentina, Chile, Peru and many parts of Europe, in addition to thousands of trails in North America.

Adventure Consultant / Trip Manager
Glenda has been a lynchpin in the JJUSA team for more than 12 years and many of our Jamboree attendees have come to know her as their contact in the office who can answer any questions regarding registration, events, etc. Raised in nearby Fair Oaks, California (but currently residing in Georgetown,) Glenda by no means spends all her time in the office, and enjoys the many settings, states, and trails she’s experienced while wheeling, most notably her time tipping on Hell’s Gate with her friend. In her free time at home Glenda enjoys gardening, cooking and hosting dinner parties.
Director of Finance
Nancy’s 30 years of experience in financial and administrative work for family owned and small businesses makes her a perfect fit for the JJUSA team. She not only tracks and manages all financial elements concerning Jamboree programs, but she also manages the budgets for media and corporate programs. Her attention to detail enables the rest of the team to handle the logistics and number of moving pieces, without the fear that financial concerns can bring. Nancy is sharp, quick and wise in her financial work, and a ‘newbie’ when it comes to off-roading, but she’s quickly getting wheel time and enjoying new adventures on trails like Pete’s Revenge during the Parker Arizona Jeep Jamboree. At home, she’s had plenty of adventure raising twins with her husband Michael, and in her spare time enjoys performing in local choral and theatre groups, and recently took up ballet.

Ty came to JJUSA with a background deeply rooted in the off-road community having co-owned Central 4-Wheel Drive, a company he worked with for 25 years in all manner of roles throughout their California, Oregon and Washington locations. An avid outdoorsman, Ty owns a 2000 Jeep Wrangler (TJ,) and spends his time camping, hiking, and fishing in addition to off-roading. One of his most memorable off-road experiences was re-tracing a portion of the fame “Expedicion de las Americas” in South America with JJUSA vice president, Shawn Gulling.

Corey came to JJUSA from a near opposite of the outdoor off-roading world. After spending 23 years in title insurance, he decided to pursue his passion for the off-road industry and switched to a marketing position for GenRight Off-Road, and then MetalCloak where he acted as an educational representative across the country. Seeing an opportunity to create an outlet for the Jeep and off-road community, he created modernjeeper.com, and began attending Jamborees as a participant. In 2015 he began working for JJUSA utilizing his knowledge of both the brand and off-roading, with the community he had been involved with. His pride and joy for personal use is his 2002 Jeep TJ, “Spike,” that he purchased new and now sits on 39” tires and is stretched to 101.” Having wheeled across the country, he still considers Moab his ‘backyard’ as he lives a few hours away in Ouray, Colorado.
Director of Registration
Mike is in his early 20s but has already lived much of his life outdoors beginning straight out high school working in construction, made a jump to try out island life working in Hawaii, but realized his true love was found amongst the trees, mountains, and lakes. After getting an opportunity to work part-time with JJUSA, his commitment to the job and impressive performance solidified a full-time position. In 2017 he was promoted to Director of Registration. Mike has worked on product launch programs for the Jeep Grand Cherokee, Jeep Cherokee, Renegade, and assisted on countless media programs in Moab, Utah, as well as the Rubicon Trail. In his spare time, he drives a Jeep Renegade as his personal vehicle and counts Moab as one of his top off-roading locations in the country.
Savannah is a Georgetown native who came to work with JJUSA through her role as a hospitality vendor for the Rubicon trail. Having worked for eight years previously in food and beverage management, Savannah’s friendly and outgoing personality was a natural fit for the Jamboree staff. In her registration role, Savannah assists with all the details that make our events go smoothly and happily answers the many questions many attendees have. Her favorite off-road locations include Sand Mountain and the Rubicon trail.
Shipping & Receiving Manager
Rhiannon is based in our Georgetown headquarters and manages the large job of overseeing all of our shipping and receiving. With 30+ of Jamborees around the country taking place week after week, her attention to detail is crucial to ensure all of the materials we need are constantly replenished at events and all the stock is kept up to date so we can offer our Jamboree attendees the best variety. Rhiannon had a passion for off-roading instilled in her from a young age when she was given her first driving lesson at age nine in her uncle’s Jeep, which was the same Jeep she had been brought home from the hospital in as an infant. Her longtime love of wheeling has carried into her family and their outdoor activities, which include time at their cabin, camping, boating off-roading and connecting to nature as much as possible.
