Training Philosophy

I am dedicated and passionate about helping each of my clients feel, move and look better!


An engineer at heart, I always focused on movement of the human body in its natural form, which led me to launch a career in 2002 as a fitness professional. My passion for fitness commenced as a young competitive athlete and continued throughout my adulthood. After working as a certified personal trainer for local, reputable fitness facilities, I started my own personal training business in 2007. With high demand and goals accomplished, in 2011 I partnered with Geoff Robison to establish Custom Kinetics.


A native Virginian, Tim resides in Ashburn with his wife and three children. In his spare time, Tim enjoys home improvement projects, cooking, playing golf, shooting hoops, dancing, playing with the kids, and spending time with his large extended family.
