About Dan

Dan’s mission is to make you a healthier person so you can improve the quality of your life.

Dan started training clients in 1997 because he felt it was time someone offered individualized, evidenced-based, fitness and self-defense programs rather than hype or fad.

Dan’s philosophy centers around the fact that human movement is a complicated and coordinated effort between your muscles, skeleton, and metabolism, and everyone is different. Knowing how each of the systems of the body work, independently and in concert, is essential in the development of an effective fitness or self-defense training program.

Dan has worked with notable organizations such as Life with Cancer and has taught fitness and wellness classes at Northern Virginia Community College to ensure the next generation is well prepared to deal with the growing prevalence of chronic disease.
