Train with Me!

I jumped all in and opened my training facility in 2021. The culmination of my life's work as a sports medicine athletic trainer, fitness product inventor and health care advocate. Our integrative approach addresses physical dysfunction, lifestyle influences, mind-body connection, active daily living exercises and high performance training.

We have dedicated spaces with private sport medicine treatment rooms, massage services, open gym area with weight equipment, cardio machines and space to ride your Si Board. The 17 foot high concrete wall is ready for our Power Rope Ball and Medicine Ball throws. Additional areas for workshops, a cubicle to take notes in and kitchen area to make your recovery shake.
