Eager to embrace the healthy Colorado lifestyle, she dove into personal training and never looked back. Since then she has managed training teams with several large health clubs in Boulder and Denver, written three books on health and wellness, and worked on fitness videos with the likes of Valeria Bertinelli and Bob Greene. Allison is passionate about creating personal training teams that provide exceptional service and deliver lasting results. In her free time, she enjoys singing with St. Martin’s Chamber Choir, and traveling with her husband.
