"Over the years I've worked with a few trainers, and he's hands down the best.  He's very personal, and cares a lot about his clients.  He's all about setting and documenting  long and short term goals.  One of the things I liked from the very start is his very scientific and measured approach."

"Unlike a lot of trainers out there, he's very accommodating about your schedule.  We've worked out together at Diakadi, 24 HR Fitness, Kezar Stadium, and even in my apartment." 

"My best marathon time was 4:20 and I just couldn't figure out how to get my time down.  With Jon's plan, I accomplished my goal within 4 1/2 months (twice; 2 separate marathons).  I also lost 20 pounds and have never felt stronger.  

Jon is very knowledgeable about what he does and so supportive; he personalizes each workout plan to the individual.  Even when I have a bad day, I leave our workouts feeling like all is right again.  With Jon leading the way, I know I will always make it to my next goal! "
