About GCF


Our founder and senior coach, Angel Santiago, started Gym City Fit for everyone to enjoy a proven system for corrective, functional, pain-free fitness. In an industry full of let downs, he wanted to take care of people who seek answers to their health concerns by joining a gym.

There are two things we don’t like we want to change. First, we want to bridge the gap between the clinical world and fitness world. What do you do after physical therapy or chiropractic care? Second, we want to develop great people into great trainers. We are tired of seeing bad training.

Large gyms and small boutiques don’t seem to know how to fix these issues. Large gyms treat members like a transaction, and smaller boutiques lack the amenities you deserve. Both lack whole-scale knowledgeable staff to make sure you don’t get hurt.

Fitness should be individualized and customized to you. That’s why we create a customized MATRIX Blueprint Report that will tell you exactly what you should do and eat.

At first glance, we are different. But we are only different because you have never experienced fitness the way it should be. We have your best interest along with our caring and knowledgeable staff you can experience.



“Build sound mind, with the synergy of strong body through great nutrition and true fitness” 

We believe our first responsibility is for the well-being of our members. We provide each member with our tri-pillar system for your success; 1) Recovery 2) Nutrition & 3) Exercise.  We act as a bridge between the medical world of pills and surgery and logically-driven-exercise prescription.  In meeting their needs, everything we do is of the highest quality and integrity and we will provide the best experience to fitness in an industry full of let downs.

We are responsible to our employees, the men and women who work for us each day and represent The GFC brand. We strive to create the best culture for our staff by giving each of them the safety to speak freely – respectfully sharing their thoughts to help us deliver our promise to our members. We pride ourselves on compensating employees better than our competitors. At GFC employees are set on a path from day one that gives them a future within this profession. Our staff motto is “Check your ego-keep an open mind” – meaning each day is an opportunity to read or listen and build upon the previous days to be the best in his or her industry.

We are responsible to the community in which we work. Our character shall be displayed and regarded as impressive outside our walls as within. We will morph ourselves with local businesses to provide a safe environment for our city. We will offer our services to any and all who will let us to help educate and inspire the youth of our community.
