Karishma Patel

Training with Jae has been a game-changer for both my mental and physical health. For the first time in my life, I actually look forward to my two training sessions each week. What I love most is that we have fun and share plenty of laughs—but don’t be fooled, Jae makes sure you put in the work and never cheat yourself. The ultimate hype girl (man)! I couldn’t ask for a better trainer.

Alli DiMaggio

It is rare to find a personal trainer who not only understands biomechanics and performance, but also has my back. That unique combination is exactly what I found in Jae. Jae has a gift for crafting training programs that align with my goals and keeps me accountable, never allowing me to sell myself short. He transformed my workouts and leveled me up across the board. He trains me like an athlete, pushes me to a high standard of excellence, and keeps my focus locked in on results. Each session moves me forward without ever feeling overwhelming, and he somehow makes the hard work genuinely fun. After a year and a half with Jae, the progress is undeniable. I’m grateful every day that he’s my trainer and would recommend him to anyone committed to becoming the best version of themselves.
