I have been going to GCP for about 2 years. I guess you could call me a gym hopper as in I would go from one gym to the next but never felt comfortable anywhere until I found them. Coaches Trevor and Nate are amazing at what they do. Not only are they very knowledgeable about health and fitness they truly care about their clients. If you are struggling with anything they will check in on you and see how they can help whether it be emotional support or weekly check ins. Besides the coaches the atmosphere is great! The other clients that work out there are some of the funniest and most caring people I have ever met. It truly feels like a family.

I have been training for about 6 weeks now and every time I complete a workout I feel so great and refreshed (but slightly exhausted)! Trevor is such a great trainer and knows so much about how the body works and how your body should look and feel during each training session. I trust Trevor 100% and have enjoyed learning something new about my body and have been so excited to see the new things I can do each time I train. My favorite thing about the training sessions is that each day is different and when we finish a month the sessions and workouts change. I love that it isn't the same thing over and over again. Get off your boring treadmill and come train in a super fun group setting!

I've being training at GCP for over 2 years. Nathan and Trevor constantly provide support and encourage everyone to work harder and do better. It was always tough to keep up with gym routine. However, GCP never felt like a gym and I genuinely enjoy going to classes and having a laugh while training. The class atmosphere is very welcoming and open to all levels. There is never a dull moment! Emphasis is on fun and fitness. Highly recommended!
