Client Testimonials

Dennis is an excellent and experienced trainer with a wonderful personality to boot. I found his workout plan non-intimidating and extremely manageable even as a bigger girl with a tight schedule. I would happily recommend Dennis to anyone looking to improve their fitness life.

Gabriell Papp

I usually don’t take the time to leave reviews online and I rarely give someone 5-stars. For Dennis and Core Fitness, however, I will make the exception. Dennis is a knowledgeable and skilled personal trainer who is committed to helping clients achieve their fitness goals. I have been working with Dennis for about 9 months and have dramatically improved muscle tone, strength, and have lost almost 30 pounds. It is rare that I get an opportunity to work with someone who is as dependable and dedicated as Dennis is, so I am happy to recommend his services to anyone who is interested in becoming healthier and getting in shape.

I’m not a typical “write a review” gal. However, I’m hoping that if you are reading this, it will be helpful. I moved to FoCo during the pandemic. I used to consistently go to the gym, but it was difficult to find one during the outbreak. I needed motivation, but struggled mightily. After getting on line and looking around, I reached out to Dennis! He was the right fit! We spoke about my goals and my needing a “kick start” of accountability. I had the tools at home, but not the “stick-to-it-ive-ness” to finish my workouts. Dennis encouraged me to keep moving and challenged me in our on-line sessions. I was never bored with his routines, perhaps a bit sore, but never bored. 🙂 Summer has been a bit crazy, but his consistency in schedule and with the ability to have a few “make-up” sessions when I couldn’t make it, was great! He is definitely a 5-star guy. If you are on the fence, get off and get going with Dennis…you won’t regret it!!
