Cyndi Krebs | Certified Personal Trainer

Cyndi is a Certified Personal Trainer with the American Council of Exercise, holds CPR and AED certification, and is the smiling blonde often seen behind the desk at Active.  Cyndi became a personal trainer to help people of all ages, shapes, and athletic abilities feel comfortable in their bodies, based on the success she had in getting into shape and re-charging her own health and life. 

She maintains an active lifestyle and helps promote that in all her clients. She has been with Active for over a year, working closely with Dave in the development and success of the A-3 program for youth athletes. Being a mom of four, ages 17 to 6, Cyndi loves the passion young athletes bring to their workouts. Cyndi is also in charge of most of Active’s administrative work. In her spare time, she enjoys walking, TRX workouts, skiing, cooking, hanging out with friends and being outdoors!
