About Jesse

As a former corpotate professional sitting in an office for 10-12 hours a day, I know how difficult it can be to get in great shape while juggling your career, family and social life. 


I used to wake up at 4am every day to workout before work and have to haul my gym bag and "meal bag" filled with 7 small meals for the day on the subway. It was the absolute worst . . . But I did it because I really wanted to be in shape. 


But years later after becoming a personal trainer, transforming my own body, and helping dozens of others to do the same I realized that those massive sacricifces and time commitments aren't necessary to get in the best shape of your life.


I use proven strategies to help you train efficiently in 45 minutes or less, boost your metabolism, and build lean muscle. 


I keep my client base limited so I can 100% focus on delivering the best coaching that will get you results every time. I'm a firm believer in keeping you accountable away from our in-peson sessions and I do this by providing more workous to follow on your own, a super simple nutrition protocol that doesn't require preparing 5 meals per day, and checking in with you frequently. (Maybe even going grocery shopping with you)


In 2018 alone I've had many people lose 20 lbs, two lose 30 lbs, two lose 40 lbs, and one lose 50 lbs. 


I have been working with clients in NYC for about 6 years now and love it! I think everyone should have a coach or Personal Trainer, including us trainers. 


I'm a Men's Physique Natural Bodybuilding Competitor, Speaker on corporate health & fitness, and soon to be author?


Stay tuned for that one...


I'm a big knicks fan and Ice Cream is my favorite food.

The nutritional program I got from Jesse changed my life! I lost a total of 40 lbs in a few months after Jesse motivated me to change my lifestyle. All I needed was his training help and talking about how to improve nutrition. Thanks to Jesse I have a different outlook on life.

Ever since I started working with Jesse and starting my nutrition program, I have been nothing but happy and confident. I was consistently pushed to better myself everyday by checking up on me and providing new workouts and nutrition plans throughout each week. They made it easy for me to talk to and converse about nutrition and the different products and was very open to any questions I had. I worked with Jesse specifically and he was always eager to help. I can honestly say I would never have succeeded in losing the 15-20 pounds without him.

A few years ago, my knowledge of working out extended to solely competitive swimming and running. Since then, my involvement with Rose Fitness has opened my eyes to new and creative workouts that have given me a new appreciation for fitness and what it can do for me personally. I have a great amount of respect for the company and all of its practices.

I was able to see changes within the first few days and weeks after having my consultation with Jesse. It’s a personalized workout plan that fits your schedule and goals. Very hard to find a Personal Trainer that invests in your results to the degree that Jesse does. I lost 6lbs in the first 8 days and dropped 6% body fat in the first month.
