Matthew Sellen, PT, DPT

Growing up in Wisconsin, Dr. Sellen was a competitive hockey player and runner. As an adult his passion for competition and movement has led him to compete in 4 marathons, 2 Ironmans, multiple obstacle course races, become an RRCA certified running coach, and even learn the basics of parkour.

He spent 9 years as a software developer, but his passion for teaching movement and wellness led him back to school to earn his Doctor of Physical Therapy from the University of Colorado, and he’s never looked back. 

Matthew feels best when lifting heavy, running, exploring quadruped movements, wrestling his dogs, playing with his wife and son, or drinking a cup of coffee with high fruity notes.

Originally from Southern California, Oliver graduated from UCLA in 2016 and it didn't take long to figure out that a normal 9-5 job wouldn't help his health in the long run. Currently, Oliver has been doing Personal Training for over 6 years, and Bodywork for over 5 years. He started his training career at 330lbs, and over the next year and a half he committed to losing 110+ lbs. and has kept it off ever since. Oliver's training style primarily focuses on weight loss and injury management, as these are areas he has overcome himself. He brings a positive attitude and disciplined mentality to every session, pushing clients not only in the gym, but throughout the day to make healthy, informed decisions on diet and recovery to make sure clients are reaching their goals. As a former powerlifter and athlete, he can also bring the intensity for HIIT and strength training sessions. His experience with bodywork started at the original Stretch Lab in Venice Beach, CA and currently he is a Teaching Assistant at Denver Integrative School of Massage. Oliver has seen great results with clients by successfully integrating massage and other recovery techniques with his personal training. As a recent Colorado transplant, Oliver is finding new outdoor activities all the time, including completing his first triathlon in Fall 2022 with plans on further endurance training! Some of his hobbies include skating, hiking and acroyoga.
