O'Bryan "OB" Hearn
I have been a personal trainer since 2013 and I absolutely love what I do.
Like most people, I also struggled with bad habits that I managed to overcome. I wasn't leading a healthy lifestyle and started having health concerns. I knew a change needed to be made when my son was born and my health was in jeopardy. My starting weight was 245 lbs and now I'm maintaining at 175 lbs. I continue to live by the 3 D's: Determination, Dedication, and Discipline. I'm excited to share my story, and with my support you will have your own success story too!

I have been training with O'Bryan for 8 years now and he is awesome!! He is good at his craft and easy to get along with. He knows what I can and cannot do and trains me, accordingly. His classes are great too. Individual or group training, or even attending one of his classes is worthwhile for my body, mind and soul. ~Priya

"I have worked with Obryan for more than eight years. He was wonderful with working with my son who is on the spectrum. When my boys went to college it was MY turn to focus on getting healthy and fit. He tailors each session to my current needs (or pains) and NEVER gets impatient with me on my "slow days". Obryan is doing a fabulous job of supporting me on this journey and I look forward to many more years!!! "

As a former athlete that has played football on every level who is now in my early 50's, I can appreciate the knowledge and patience Mr. Obryan shows in his approach to personal training. He pays close attention to how his clients bodies respond positively and negatively; which allows him to adjust to a personalized workout for his clients. Whether you are an athlete or trying to reach certain health goals, I highly recommend Mr. Obryan to navigate you to your personal fitness goals.

Coach OBryan did an amazing job of coaching my seven years old son, who was afraid to even get on the court. Although Coach OBryan coaches older kids, on my request he made an exception. He made the sessions fun while pushing my son to new limits every week. I have seen my son not only play better at basketball but I also see him having more confidence. Basketball is now his favorite sport. We highly recommend Coach OBryan.
