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.

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.

Jessica is Director of Recovered Generation at Ormat Technologies, Inc. where she is working to reduce the carbon footprint of the oil and gas sector by deploying clean energy.  Her years of experience in the midstream gas business exposed countless opportunities to capture wasted heat, so her work now is a labor of love.  Prior to joining the energy business, she worked in various positions in energy and environmental policy, including the White House Council on Environmental Quality, The Wyss Foundation, and the United Nations Foundation. Jessica serves as Board Chair for the International Mountain Biking Association and previously served in the same role for the Colorado Youth Corps Association.  A Colorado native, Jessica's true love is rolling down any of the state's alpine trails or skiing the backcountry during off-season when she is not chasing after her toddler twins.

Michelle is a Director of Development for SunShare, a solar photovoltaic developer based in Denver.

She also served on the Colorado Parks and Wildlife Commission from 2012-2020 representing recreation and nonprofits.

Michelle began her mountain biking career in the 80’s on a shiny red, banana seat kid’s bike, following her older brother and his friends jumping out of ditches on the farm, and started racing in 2005. She worked at the Denver Spoke bike shop through college and joined Team Yeti Beti in 2010. Riding a bike is vital medicine in Michelle’s life and keeps her connected to this amazing community.
