Aaron Clark Policy Manager - Government Affairs

Aaron is a gearhead by birth and dropper-post lovin' weight-weenie by choice. Having discovered a lifelong love for all things bikes back in Detroit in the early 90's (aboard his fully rigid, budget-minded Nishiki Crossroads, no less) he began racing his bike all over the Michigan woods. This eventually led Aaron to Colorado and eventually to IMBA in 2012 where he works on backcountry mountain bike trail access, policy and legislation as part of the Government Relations team. In his little spare time, Aaron coaches cyclocross at a local high school. His best rides are with his wife and two boys who, after careful crafting, now share his love for riding.

Chris is a trail builder born and raised in the suburbs of Dallas-Fort Worth. His passion for the outdoors began when he spent summers and weekends in the local creeks searching for reptiles as a kid. He was introduced to cycling at a young age by his father and would join in weekend tandem rides with the local bike club. Though riding downhill and racing enduro are his true loves, you might find him ripping it at a weekly gravel bike race. His deep affection for the sport grew once he started building and helping maintain the local mountain bike trails in the area. If he’s not hanging with his lab mix, Ms. Izzy, or shredding trails, he’s either backpacking, hiking anything that looks fun, or snow skiing in the Rockies.

Colin McMillan Trail Specialist - Trail Solutions

Colin's life on two wheels developed early on in the piedmont of North Carolina. Home built jumps and racing down power line trails on dirt bikes were his preferred methods. His love for the outdoors took on many different forms: skiing, climbing, and backpacking were some of the few. After high school Colin saw no better way to pursue the outdoors than to explore Nature's Mountain Playground, Pocahontas County, WV. There he developed skills in snowmobiles, ski and bike patrol, and open water rescue. During these years he realized he had a passion laying dormant… trail building. This led him to join the local Poca-Trails club where he gained the skillset to maintain and revamp some of his favorite trails. His desire to expand his horizons brought him to IMBA Trail Solutions.

Marty started mountain biking in '99, when the usual way to begin riding was to be dragged on a death march by well-meaning friends who left you miles behind with no way to fix a flat. Thankfully, this didn't prevent her from falling in love with the sport (and also becoming a professional mechanic). After a previous stint at IMBA, she worked on the manufacturing side of the industry as well as with local advocacy groups, and now she's back on staff. She's a former photojournalist who uses the noun "flowgnar" like it's an actual word, while at the same time correcting people for saying "irregardless." She loves alpine sunrises, long descents, and fixing broken things to get people back riding. Her stoke level is high, as is her desire to help communities reach their trail development goals.
