“Jim was a big help and as a trainer. You know where people with weight problems come from along knowing how to lead them to success. You were fun on the good days, a good listener and compassionate on our not so good days. You really were part of our success, and still are! Thank you!”

– Annie N.

“Jim is a phenomenal trainer. He understands the physical and mental aspects of weight loss. He is continuously committed to his clients and their journey for better health.”

– Anne R. (lost 82 lbs.)

“For about a year, I have been training with Jim. He has been one of the most positive, fun, and encouraging trainers one could have. He helped motivated me to eat better and become more active. He has become a mentor in my “journey of fitness” and there is no way I could have done it without him.”

– Colleen G.
