JON HAS ALWAYS BEEN AN ATHLETE. HE WAS A TIGHT END/CORNERBACK, SHOOTING GUARD, MIDFIELDER EXTRAORDINAIRE, BUT BASEBALL WAS HIS PASSION. PITCHING AND PLAYING THIRD BASE ALL THE WAY THROUGH THE COLLEGIATE LEVEL, HE HAS shared the diamond with professional players, coaches and trainers. after graduating college, jon traded in his spikes for running shoes and in his first race, finished top 10 in his age group!

combining his passion for physical activity with a degree and over 20 years of experience, jon launched jdlt in hopes of providing top-notch personal training and run coaching services to anybody who wanted to get better.

Whether its training with jdlt in person or online, we will help you accomplish your goals. we've helped runners qualify for boston, individuals lose 100+ pounds, designed hundreds of training programs, and now we want to help YOU!

"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! "

"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."
