His expertise and work have been featured by ESPN, Fox Sports, Good Day LA and the Orange County Register. Today, Constant Performance brings that breadth of experience to a wider audience through individualized online fitness and sports-performance programs and one-on-one consultations.

His philosophy remains unchanged: “We Are All Athletes” and “We Are Stronger Together.”
