Jason is a Certified Strength and Conditioning Specialist (CSCS) with the National Strength and Conditioning Association (NSCA),  life long scholar of human movement and performance, as well as a former collegiate athlete & D1 Men’s Club Lacrosse Coach. In 2009 he earned a spot in the Top 20 (220lb) Powerlifters and set a new WPF World Record in the Deadlift.  Currently, he has competed as a drug free powerlifter in the 198, 220 & 242 lb weight classes and is listed on the All Time Ranks.

In 2014, after a routine physical, Jason was diagnosed with a severe congenital heart condition which required immediate attention.  On January 29th 2015, he underwent a 4 hour open heart surgery procedure to repair his bicuspid aortic valve. The surgery was a humbling, yet amazing experience.  During the forced time off Jason continued to hone his coaching, technique and programming skills. It gave him the ability to relate to many of his novice clients as he re-experienced what it was like to start from scratch at 35 years old. He has since made a full recovery and stronger than ever!   

In addition to his accomplishments on the field and as a strength athlete, Jason has also competed as an endurance athlete, and has the training and nutritional knowledge that has allowed him to successfully (& naturally) both gain and lose over 40 lbs in last few years! Although the pursuit of strength and speed has always been a passion of his, Jason doesn’t subscribe to a single training philosophy.  He has studied and implements a variety of training modalities and techniques designed to improve all aspects of human performance while striving to prevent the risk of injury in the gym and on the field. Workouts are fun, full of energy and offer innovative exercise techniques guaranteed to get you looking, feeling and performing your best.

When you think of the typical strength, health and fitness professional you most likely don’t think of someone that used to be morbidly obese that eventually turned their life around, but in Dennis’ case that’s exactly what you get.

Weighing in at 165 pounds in high school, he watched his weight slowly creep up once his days of playing football, baseball and judo ended. The poor eating habits he had gotten away with in his active youth now began to slowly take their toll on his sedentary body. His weight eventually topped out at 288 pounds, he had a list of prescription medications he took, and he suffered from physical ailments that grew at an alarming rate.

Of course all along the way to becoming morbidly obese he tried every fad diet that came along, but as is almost always the case with such diets he ultimately failed to either lose weight or maintain whatever meager weight loss he was able to temporarily achieve. Then, thanks to Game Time Strength, he discovered something old, something that has stood the test of time, resistance training and macro nutrient manipulation, and lo and behold he started to see the results that had eluded him for so long.

Before joining the coaching staff at GTS, Dennis spent over 25 years honing his skills as an educator and trainer, helping both individuals and organizations improve their performance and achieve their goals, and it’s this experience combined with GTS’ proven training and nutrition programs, as well as his own success at overcoming obesity that make him such a passionate and effective trainer and coach.

Today Dennis is in the best physical shape of his life. He not only no longer takes any medications or suffers from any physical ailments, but he holds the USPA California state record in the deadlift for his age and weight, and has been ranked in the top 30 nationally in two different weight classes according to When he’s not helping others achieve their strength and weight loss goals, you’ll most likely find him off on some adventure doing things that his once obese self could only dream about.
