Charles began working at Pacific Bicycle a top 100 retailer in the US that sponsored professional cycling team Kelly Benefit Strategies and its own Elite Womens Triathlon Team . It was here his passion for bike fit and mechanics budded. He was mentored by Eric Pritchard for several years. Eric was always willing to teach Charles in the ways of ergonomic bicycle fit and in turn Charles worked as an apprentice helping him during his fits changing saddles, stems or whatever he could do to help so he could watch and learn. Eric would later go on to open a shop with John Cobb. Eric was taught his skills by a person who learned directly from Andy Pruitt.

Later on Charles would go to a shop called Big Swingin Cycles. This is a high end shop in San Francisco that focuses on building custom dream bikes and really enhancing the shop to consumer relationship. Here he helped many Category 1 riders including the Irish National Time Trial Champion. This is where Charles was able to pursue his certification from USA Cycling as a Certified Race Mechanic and Certified Event Official by attending an intensive course offered at the Olympic Training Center in Colorado. It was here that he was taught by top industry professionals how to perform as a professional race mechanic. In Colorado Charles met the director of Mavic Service Course. One month later he was riding in the yellow Mavic car at one of the longest running top professional and stage races in America, The Redlands Bicycle Classic.

Wanting to work more as a mechanic in the professional peloton, Charles sought out work for On Support, a neutral service outfit based in Minnesota. Charles worked at the Nature Valley Grand Prix Stage Race as a mechanic and also assisted the company with the Qualcomm Million Dollar Challenge, a ride consisting of 100 people that travels from San Francisco to La Jolla California over 6 days. At this ride Charles assisted team Garmin Slipstream, Floyd Landis and other top athletes. Other events include helping Stuart Hall High School mountain bike team at the California State High School Mountain Bike Championships and working with his shop at their own cyclocross race, The Lion Of Fairfax.

He also completed a two week internship with renowned bike fit expert, the Bike Fit Guru, Chris Balser. Charles immeadiatly was in tune with everything Chris purveys. Comfort, efficiency, injury prevention and rider feedback to make the bike fit the athlete, not the other way around. These are the keys to Bike Fit. He also was taught one on one by Bikefit Systems founder and Olympic Gold Medalist Paul Swift. He received his certification as a Certified Bikefit Pro from Mr. Swift.
