My training approach is to work with clients to find the right combination of physical activity, intensity, mental focus and a healthy approach to nutrition to create a personalized recipe for success. A functional approach to training is to not focus on training individual muscles, but the entire body by enhancing natural movement patterns. At all ages and levels of fitness, I believe we can all improve our wellness and live a more productive life.

Philosophy: For 30+ years I have shown how exercise is a joy, a gift, an opportunity. I want others to get to the point where they do it for the love of it, for empowerment, for destressing, for the health of it....not to lose ten pounds in 7 days. I challenge everyone to be the best version of themselves. Exercise is as much physical as it is emotional. My passion is taking the intimidation factor out of fitness by providing a personalized touch. Once you feel comfortable with the people around you, their support and friendship can be all you need to keep motivated and accountable. Through exercise, your confidence and the ability to self-motivate improves. With proper execution, timing and progression of exercises, goals are achieved through sweat, hard work, and a desire to have fun.
