I broke my back about 9 years ago. I had three back procedures and went through about four different physical therapists that said they couldn’t help me. I almost gave up being able to walk and do my job without pain. Jonathan fixed my pain in about six months and did what doctors couldn’t do for years! I’ve been able to backpack across Europe, backpack in the Grand Canyon, and do my job pain free. I cannot recommend him enough for giving me my life back

I have been working with Jon since Nov 2025. He handled me for my first Powerlifting competition (which I trained myself for). After just one day of working together, I knew he was the coach for me. Since then, I've competed in a USPA Regional PL competition, as well as at the USPA Ultra Nationals competition. In less than a year, he has guided & pushed me to reach all my goals. And we have more planned for coming years. His plethora of knowledge shows in his programing and his critiques. When you sign up with Jon, you're signing on for years of coaching and guidance towards all your goals. You will not be disappointed.

Jon has transcended my gym experience since I began working with him. When I first began working with him I wanted to be bigger and stronger, was 200lbs. Could bench 290lbs, and squat and deadlift 435. I now bench 410, deadlift 640, and squat 565. His knowledge is ever growing and pours his heart into progressing his clients. Any pains I’ve had he had helped me rehab and grow. Thank you Jon for all you do!

I began training with Jonathan 3 months ago and can honestly say this one of the best decisions I made. Having never really trained and being a heavier guy, I was nervous about how things would go. From my consultation, where he asked about my personal fitness goals and what I would like to achieve, Jonathan made me feel comfortable and unintimidated. During our initial session Jonathan assessed my fitness level or lack thereof, but never made me feel ashamed or embarrassed, he assured me the only way to go was up from there. He's knowledgeable, personable and able to help you push yourself beyond your limits in a good way. As of today I am down over 20lbs from where we started, we train 3 days a week and I find myself growing stronger with each session. If you're looking to start a training program, I strongly suggest Jonathan - you will not regret it!

I've tried to lose weight on my own for nearly two years now with little to no success. In the first month of working with Jonathan, I lost over 12 pounds and still see weight dropping. He was very accommodating with the gym materials I had. He created a personal workout routine just for me, which improved my weaknesses and strengthened my strengths. The diet plan included simple and delicious meals that soon became some of my favorite meals. Jonathan is very supportive in the one on 1's, not letting you give up on yourself, pushing you to your limit to prove to yourself your real strength. He will believe in you and your goals more than you do. Jonathan will be there every step and every pound you lose. He always makes sure you're comfortable but still trying your hardest. He has such a passion for his job that is translated to pure excellence in his position. I would and have recommended friends to Jonathan.

What is your typical process for working with a new customer?
I typically have clients fill out an intake form, and we would either meet in-person or via phone call/Zoom to discuss injury/training history, goals, etc. Once we have all of these set I can go through a movement screen that will inform my exercise selection.
What education and/or training do you have that relates to your work?
I have a B.S in Kinesiology from the University of Central Florida, along with personal training certificates from both NASM and ISSA. I hold Tactical Conditioning and Nutrition certificates, alongside my experience as a National level powerlifter (2018/2024/2026) and Regional level collegiate rower.
