I am analytical and knowledgeable, as well as fun to work with. My education in sports medicine and exercise science has provided my past clients with a supportive and positive environment. I spent 7 years working with clients averaging 40 to 70 years of age helping them with their various health and injury issues. I have a strong commitment to purpose. I am always after the “why and how” of an issue. My specialties are injury prevention, post-rehab, strength training, and overall health. Whether you are dealing with an injury, wanting to get stronger, or just want to lose a few extra pounds, I will create an individualized workout tailored to meet your goals and needs.
My training philosophy emphasizes form, function, and the quality of movement. I see the human body like a fine sports car, where proper alignment and mechanics yield performance.

Achieving a healthier, active lifestyle means that we are able to enjoy a higher quality of life and to continue doing what we love!

For 10 years, I’ve assisted young adults, baby boomers and seniors to re-enter exercise programs, build bone density, achieve a healthy weight, and increase balance and core strength.  I’ve also worked extensively with people recovering from painful back injuries and shoulder, hip, and knee replacements to help them successfully resume activities of daily living.

Exercise can help by improving our self-esteem, boosting energy levels and reducing daily stress.  Whether you enjoy tennis, dance, golf or simply sitting on the floor to play with grandkids or pets, I can design a safe, effective and fun exercise program to help you meet your fitness goals.

Each client’s unique program is based on a functional core training model which uses multi-planar exercise movements found in our daily activities. These training movements such as squatting, lifting, turning and bending, help us increase our strength, mobility, cardiovascular endurance, core stability and balance.

It would be my pleasure to partner with you to develop your personalized workout for optimal health.  Come by the fitness department or reach out to me online.
