Testimonials

"Dorothy has helped strengthen my back so that I am no longer bothered with my lower back pain. I also had trouble with my legs that bothered me a great deal; that is now a thing of the past."

Carolyn L. Brewer
"Dorothy contributes a great deal of personal experience and continues to keep up on the most current training techniques. She has a flair for making training interesting and fun."

Robert G. Watkins III, M.D.
"If I did not have Dorothy in my life pushing me I don't think I would have been able to accomplish my 60+ pounds of weight loss. I have more to go but I know I'll be able to achieve it with Dorothy in my corner."

Brittany Brayton
"Dorothy has trained both of us (husband & wife) for several years and does a great job. Most of her clients are advanced in age, and her exercises are always age-appropriately tailored to each person's condition."

Sheldon Halpern
"Motivating, encouraging, caring and sensitive to each individual's needs."

Susan J. Long
"Dorothy makes continuing education a priority in all aspects of her life and continually adapts to the changing demands of the fitness field."

Paula B. Toshima
"Vim, vigor, and vitality: I get these 3 "v"s from Dorothy."

Betye Burton
"A bad knee drove me to seek relief through surgery. Dorothy was tremendously helpful in strengthening the leg around the knee before surgery and in the recovery and rehabilitation afterward. I was playing golf again 10 weeks after the surgery."

D.K.
"Dorothy takes fitness seriously as both an accomplished athlete and trainer with an exceptional ability to teach."

John Richards
"Ms. Waterman has literally saved my life. Her techniques in weight training and personal development have transformed me from a lethargic, overweight individual to a thin, muscular, and healthy member of this community."

Darrell G. Brooke
"Dorothy is fantastic. She has been working with my 92-year-old mother for years with an invaluable program of strength and balance, keeping my mother safe and strong. My mother has renewed vitality; her workouts with Dorothy are a critical component of her quality of life."

Sigrid Burton
"Since I started working with Dorothy my strength has improved immensely and my body has toned up. The best thing about Dorothy is her continued interest in working with older adults to keep them fit and strong, an interest that most trainers don’t share."
