Coaching Staff
Jon Mengering Director of Competitive Aquatics

Day to Day Coaching On Deck: Lead Coach of FMAC - Pre-Senior 1 and FMAC - Senior 1. Will oversee Senior 1 program wide as well. 


My name is Jon Mengering, some of you may know me better as Big Show and it is my honor to become the next Executive Director of Competitive Aquatics for the YMCA of Upper Palmetto Rays. As a coach I’ve been able to observe the proud tradition of the Rays swim program from afar, the excitement is very real to be able to engage with the team, community and all of the YMCA of Upper Palmetto members.

It is my goal to help the Rays program, its swimmers and coaches strive for and achieve their goals in and out of the pool. The swimmer is a complex and multifaceted student athlete, the goal for academic and athletic success can be accomplished while competing at the highest levels in both arenas. The critical piece is balance in all things, greatness is not a myth, it is available to us all should we be brave enough to strive for it and believe in ourselves enough to reach out for it.

My mission will be to empower the athletes, the coaches and everyone that supports the Rays and this program to achieve that end. We can be great, each and every one of us. Will it be easy, absolutely not; but I guarantee it will be worth it, if you’re brave enough to take the journey.

Appreciate the work, trust the process and believe in yourself; through these three things nothing can stand in our way. I believe in team; teamwork, teammates and the philosophy that brings them both together. There is nothing we cannot achieve if we commit to ourselves, our sport and our team. Hard work can be fun too! The goal is to enjoy the process, be with our teammates and learn from each other.

I’ve been in and around swimming my entire life. Starting with lessons when I was four years old at my neighborhood pool to NCAA Division 1 swimming as a member of the Clemson University Men’s Swimming Team. I began coaching with the university program in 2006 and began as head coach for Clemson Aquatic Team in the fall of 2007. I have learned from some of the best coaches in many levels of the sport, I was fortunate to swim for and gain insight from these mentors of mine and I bring that knowledge, energy and passion with me to the Rays.

I look forward to meeting and getting to know you in the coming weeks.
