Without a doubt, we believe our tour leaders are the heart and soul of Timberline. These very special men and women are chosen by Timberline, not only for their obvious love of cycling and hiking and the outdoors, but also because of their caring manner, competence and enthusiasm, and their desire to share some extraordinary experiences with a wide variety of people and personalities over the course of a season.

In most cases, two leaders will be assigned to each group. In addition to extensive cyclo touring and hiking experience, each leader will have completed a leadership training course and will have received certification in First Aid and CPR. Most guides hold Wilderness First Aid certifications from NOLS or other professional, industry wide organizations. Each guide will go through Timberline Adventures very own Guide Training Weekend, filled with updates, safety information and more. Our bicycle tour leaders are competent bicycle mechanics and will be equipped to assist with repairs and maintenance.

Barb grew up in northern New York State exploring the Adirondack Mountains. Her first job out of high school was guiding bicycle trips for teens with American Youth Hostels.  She pursued degrees in mathematics and engineering but never gave up the yearn for spending time in the outdoors.  She came to Colorado 30 years ago to take advantage of the unlimited skiing opportunities. Since then she has explored the slopes, trails, mountains, rivers and lakes all over the state and the western U.S.  An avid traveler, she has also climbed mountains on 5 continents and bike toured all over Europe and Asia. Her leadership experience has progressed through volunteer and professional work with the Girl Scouts, other youth organizations and guiding companies. Her credentials include Wilderness First Responder certification, training in Winter Emergency Care and avalanche safety, and years of teaching. Introducing youth to all manner of outdoor endeavors, taking clients on domestic and international exploration and facilitating a variety of events has filled her resume.  The natural progression to heading up one of the oldest adventure tour companies in the country is thrilling and yet seems like home.  The adventure awaits!

I have been involved with Timberline Adventures for many years as a guest and as a co-owner with my wife. We sold the business in early 2017 and I will occasionally guide. I have enjoyed using my experience from the Bay Area high technology busineses I have been involved with and applying that insight to the infrastructure of Timberline Adventures.

Guiding tours and riding and hiking with customers is where much of my time is spent during the season.

Julie first guided with Timberline Adventures in 2001. In subsequent years, she led tours in 2008, 2009, 2010, 2012 and 2013-2016.. Julie is originally from Colorado Springs and hiking became a way of life at a very early age when she made her first Pikes Peak ascent at age 12. In the mid-1980’s Julie was introduced to long-distance road bike riding which fueled the desire for many week-long tours in Colorado, Iowa and Arkansas. Her love for long distance rides is punctuated by any road that offers a steady elevation gain to ‘new heights’ such as The High Road to Taos, and mountain passes like Cumbres, Bobcat, Trail Ridge Road, and Loveland. Julie enjoys sharing the hiking trails of Glacier National Park, Bryce, and Zion with Timberline newbies and seasoned guests as well! See you on the trail!

After spending 30 plus years in the southeast, the move to Colorado became a reality about 10 years ago. I have always been an avid outdoors fan skiing, hiking, biking, and traveling for as long as I can remember.  I have taken bike tours in France, Italy, and Portugal and driven across country with a bike on top of my car to bike and hike in many unique and interesting spots in the United States.

This last year offered me the opportunity to leave the Healthcare IT world for another journey which included enhancing my amateur photography skills as well teaching skiing as a PSIA certified instructor at Copper Mountain. As one one of the most recent tour guides joining Timberline Adventures, I look forward to sharing my enthusiasm for the outdoors and spending time with the Timberline clients this season. Let the fun and adventures begin….


Tim is an all season outdoor enthusiast residing in the beautiful high country of Vail, Colorado. He grew up on the coast in Florida playing football, soccer and baseball, but as he grew older he realized his passions were in the mountains. He loves to ski, hike, and bike all over the Vail Valley. He has a background in psychology with an undergraduate degree from the University of Colorado Denver. This correlates with his passion for communication and human interaction. He strives to embody a warm and approachable aura that will resonate with people from any culture. He enjoys meeting and learning from people with diverse backgrounds and interests. It’s rare that you will find him without a smile on my face, specifically when exploring this gorgeous North American continent. He volunteers some time at the Vail Valley Medical Center and the Vail Library. He is always planning a new adventure, because he feels this world has too much to see to remain stationary


Maureen was born and raised in upstate New York, where she developed a love of the outdoors by spending many childhood vacations camping and backpacking. For college, Maureen headed out to Colorado to attend the U.S. Air Force Academy. Upon graduation, she served as a Special Agent with the Air Force Office of Special Investigations where she specialized in counterintelligence operations. Maureen also worked as a national security consultant and is currently a professor at Virginia Commonwealth University where she teaches homeland security classes.

Maureen is an experienced outdoorswoman who enjoys backpacking, mountain biking, trail running and hiking. She is also an intrepid traveler and has hiked, biked and paddled in over 40 countries to date. Maureen successfully completed two Eco Challenges, arguably one of the world’s most difficult ultra-endurance events, and co-authored a book on adventure racing. Maureen, her husband Bob and their children live, work, play and learn together on a 25 acre hobby farm, complete with a small organic garden and menagerie of quirky, but lovable animals.


I am a Colorado native (one of the few left!) and have had a love of the outdoors and fitness since I was a child playing on sports teams and learning to hike and ski in the Colorado mountains with my family. In college I became more involved in long distance running and cycling, and became hooked by the sense of adventure, inspiration and peace that it provided. That led to long distance racing of marathons, triathlons, and backcountry adventures on many continents, as well as personal training and coaching (soccer, skiing, running) for many years. I haven’t stopped running, cycling, hiking, and experiencing the great outdoors since (although the distances have changed!), and have discovered that guiding with Timberline Adventures allows me to continue my love of being active in the great outdoors. My background includes undergraduate and graduate degrees in biology and exercise physiology, so when I’m not guiding, I can often be found teaching at the university level helping the next generation of biologists, physiologists, and health professionals achieve their goals. When not guiding or teaching, I spend time with my husband and our four wonderful dogs that keep us busy and entertained (all shiba inus). 

This will be my fourth season as a Timberline guide. One of my favorite aspects of guiding is meeting people from all over the world with such diverse backgrounds and interests. Every trip I lead I meet new and fascinating people, and I always learn something new and interesting! Leading various trips keeps me curious about the local regions we bike and hike in, and helps me appreciate the amazing diversity of people and places around the U.S. I look forward to more great adventures this year! 


Not much needs to be said about Carol. Most of you all know she is the founder of Timberline Adventures. Carol and Dick can really say that they helped pioneer adventure travel. After 32 years in the business, there is no one that knows the hiking and biking routes in North America better than her..

We are lucky and happy to say that Carol will be guiding several tours this season. You may even be lucky enough to call when she is in the office working. It is always fun to talk to Carol about all the Timberline Adventures offerings.


George comes to us after 29 years of teaching high school biology. His passion for the sciences is matched by his love for adventure travel. His vacations from school and zest for life have taken him all over the world. He has climbed Mt. Kilimanjaro, hiked to Machu Picchu, scuba-dived in the Galapagos, rafted the Zambezi, fly-fished New Zealand, sailed Croatia and even lived in Australia for a year as an exchange teacher. He has led student trips to study marine biology in Hawaii and the British Virgin Islands and guided student outdoor trips all over Colorado for hiking, biking, rafting and skiing.

But, it is his passion for the National Parks that has taken he and his wife all over North America. Each day on the trail offers so much in terms of friendship, wildlife and natural beauty. He reminds us that it's not just about the destination..... be sure and enjoy the journey. George looks forward to hiking and biking with adventure-seeking ADULTS (and not grading their papers!)

A client recently remarked “Laura was born to be a guide!” A veteran guide from the early days of Timberline, Laura has returned to lead tours after a career teaching art in public schools. Before teaching, she worked at Breckenridge Ski Area in skier services and ski racing, and as a National Park Service Ranger. She designed and led interpretive bike tours for visitors to Cape Cod National Seashore. And as a self-taught French speaker, she led bike tours in Switzerland, France, and the Netherlands, and claims the capacity to smile in every language! Laura was raised in charming New England in a Civil War era house, yet made the mountains of Colorado her permanent home in 1982. When not guiding, she consults for College Board AP Studio Art, is a USSA judge for freestyle mogul skiing, and enjoys encaustic painting, mixed media and jewelry metalsmithing. Happily married to a biologist who also loves biking, skiing, kayaking, and anything outside, Laura loves the way hiking and biking slow the pace of life to appreciate your day and surroundings so fully, while separating you from your everyday concerns. She is looking forward to making memories with you on tour – come join her!


Thom has spent thirty years in the outdoor adventure field working with a wide variety of populations. This work has been with a variety of Outward Bound type programs and guiding companies. Personal travel and adventures have taken him from the Artic watershed to the deserts of Mexico, sailing in the Caribbean and a long walk through Nepal and Tibet. Raising two children and married to a National Park Ranger while living outside of Rocky Mountain National Park provided great opportunities to play in the Colorado backcountry, skiing, hiking and climbing. His personal philosophy is that we all have a great deal to learn from one another as well as from wilderness experiences and adventures. So let the fun, learning and growing begin as soon as possible.
Raising two children and married to a National Park Ranger while living just outside Rocky Mountain National Park provided great opportunities to play hard in the Colorado backcountry, skiing, hiking and climbing.
My personal belief is that we all have a great deal to learn from one another as well as from wilderness and adventures.  Let the fun, learning, and growing begin as soon as possible.
