Meet Our Coaches

Glenn Perra, Jr. - Head Coach - Owner


I have always been a sports and fitness enthusiast.  In my early years, I enjoyed playing many sports, but had a true love of football. At age 15, I started training with weights and have not stopped!  I also spent some time as a competitive amateur bodybuilder and I enjoyed training others. My passion for health, fitness and helping others led me to the medical field. In 1995, I graduated from nursing school as a Licensed Practical Nurse. During my 15 years in the medical field, I continued my fitness interests and became a Certified Personal Trainer. In 2007, I was introduced to CrossFit by my lifetime friend and current business partner, Merle McKenzie.

I quickly realized that CrossFit was the perfect vehicle for me to express my passion for health and fitness. In 2009, I left the medical field to pursue my dream and opened my first CrossFit affiliate. I am currently the co-owner of five CrossFit locations across the state.

I enjoy working with and programming for our competitive athletes and we have produced CrossFit Regional and Games level athletes.  In addition, I have helped many athletes improve in sports outside of CrossFit.  Over the past several years, I have also coached youth football, baseball and softball.  The most rewarding aspect for me has been the life changing effects I have been able to help so many individuals achieve. Watching kids gain self-confidence, seeing individuals shed pounds, improve blood-work, rid themselves of medications and ultimately returning to a healthy, vigorous lifestyle is about as good as it gets!

Merle McKenzie - Head Coach, Owner


*I graduated from Massage Therapy School (CCMT) in 1997. I spent seven years practicing Massage Therapy while also working as a personal trainer,
*I worked in 2 of the best known fitness programs in the state prior to becoming a CrossFit coach. I spent a total of 10 years working for these gyms ( Big Sky Fitness in Newington and the Fitness Edge in Fairfield).
* While working for these gyms I acquired several certifications including NASM, APEX and RTS level 1.
* As good as I thought I was during those 10 years I realized something was missing. Then I discovered CrossFit.
* My 10th year as a personal trainer is when I discovered CrossFit ( 2007). After months of experimenting on myself and introducing it to my clients I went to get certified as a CrossFit Level 1 coach. I fell in love with the program and within months of receiving my certification I open the 1st CrossFit gym in Central Ct. ( CrossFit USA).
* Knowing that my education was still far from complete I spent years traveling the country getting certified in numerous components of CrossFit training. These certifications include.


* CrossFit level 1
* Kettlebell with Anthony Delusio
*Starting Strength (powerlifting) by Mark Rippitoe
* Louie Simmons (powerlifting) Westside Barbell methodology
* Gymnastics with Jeff Tucker
*CrossFit Nutrition . Barry Sears guest lecturer
* CrossFit Olympic Weightlifting with Mike Burgener
* CrossFit Strongman with Rob Orlando
* CrossFit Kids with Jeff and Mikki Martin
* CrossFit Mobility with Kelly Strarrett
* Gym Jones level 1 with Rob McDonald
* other seminars include movement with Carl Paoli and a Masters seminar run by T’J’s gym in San Jose California.

As central Connecticut’s most experienced CrossFit coach and one of the longest running operators of CrossFit gyms in the state ( 6 years and owner of 3 CrossFit gyms) I have helped literally thousands of people through the power of CrossFit.
We have produced 1 CrossFit Games team in 2010, 1 CrossFit Games Masters athlete in 2011 and 2 CrossFit Games Masters athletes in 2012.
As proud as I am of those accomplishments it means less to me than restoring a person to a vital and vigorous life. I am much prouder of helping my 40-50-60 year old clients squat without pain, lose dozens of pounds and get off expensive and poisonous medications. I’m more interested in helping a stay home mom get her first real pull up than producing Games level athletes. As much fun as that has been.

My passion is helping people realize their true potential. I coach by one over riding principal. It’s not what I can do personally, what matters most is what I can coach you to do as an athlete.
