About John

In 2001 I was a finalist in the "Body For Life" international body transformation contest. My wife and I competed in the couples category along with thousands of others from around the world. Our goal was to lose weight and perhaps win some money. What we got was so much more valuable.
We did not win the big money, but we did lose weight and we dramatically improved our appearance. What we did not expect was just how much better we felt and how much younger we looked. We learned that exercise is the best health insurance in the world. We literally turned back the hands of time on our biological clocks.


That experience inspired us to become certified as Personal Trainers.  Since then we have both worked as trainers part-time.  In 2016 I made the decision to dedicate myself entirely to the health and fitness industry.  I recertified with the American College of Sports Medicine as a Personal Trainer.  I also went on to become certified as a Health Coach and a weight management specialist with the American Council on Exercise.


I developed a Health Coaching service called the Mind-Body Transformation that utilizes exercise, diet and meditation techniques to help people completely transform their bodies and their lifestyles.  

I have published three books on diet, health, and exercise. As a Health Coach and a Weight Management Specialist, I can help you with your diet as well as your exercise program. I have a small, but well-equipped gym in my home where I can train clients. I am also happy to meet you at your home or your condo/apartment gym.

Working with John has really changed my life. I was at a point where I would tell myself when at the gym, "what am I doing here." Nothing really made sense until John explained how the importance of maintaining a healthy mental state is the key to a successful physical state. He was able to uncover my needs and also provide me with a in depth detail on not only working out but also maintaining a healthy mindset and which lead to having a great diet that I enjoy instead of regret doing. I highly recommend John for any of your Fitness needs.
