What stands out the most is that the impact of our work together lasted well beyond the sessions and If I’ll have the opportunity to train with him again, I definitely would!

Jonathan is a great trainer Working mitts with him is a great workout plus I’m learning how to be a better fighter! Also his Physical training knowledge is really helpful for me.

My husband and I have been training with Jonathan 3-4 times a week since we moved to NYC in May 2017. We consider the time, effort and cost to be the best investment we could have made (and continue to make).

I have been training with Jonathan for several years now and I would recommend him highly to anyone interested in fitness and weight training.

Been working with Jonathan for about 3 years now and he’s the best. He works with you and your goals. Pushes you to do and be the best you can be. When I first started, I couldn’t even do a push up, but now I can do different variations. Came a long way from where I was fitness wise and that’s thanks to Jonathan. Give him a shot and you won’t regret it cause the fitness or whatever goals you want to reach, he will help you achieve it.
