Her marathon training programs have been used by thousands of runners nationwide.

She is a four-time Ironman finisher, winning her age group and placing third overall at the 2004 Full Vineman. She is an accomplished ultramarathon runner and a two-time Boston marathon qualifier. Her next big race: the three-day, 319-mile Ultraman Canada.

Dorette is a former head coach for the Nike Women's Full and Half Marathon and the San Francisco AIDS Foundation “Greater than One” full and half marathon training programs. She serves as track and running coach for the Golden Gate Triathlon Club.

Dorette holds coaching credentials and certifications from USA Track & Field, USA Triathlon, USA Cycling and the Road Runner's Club of America.
