Who we are

Founded in 2016, Sixth Union Fitness has helped change the lives of thousands of clients through our holistic approach to health and fitness. By focusing on all aspects of fitness, not only will you achieve the physique you have always wanted but it is our mission to help you create a life you have always dreamed of.

When joining Sixth Union Fitness, you not only receive personalized attention from an elite trainer, but you also gain access to a synergistic community of like-minded individuals focused on achieving success in every aspect of life. We base our workouts on principles that have been repeatedly proven over time to maximize results and increase overall human performance.

We believe that "Personal" comes before "Trainer" for a reason and one quote we try to live by is: 

“The STRENGTH of a man isn’t measured by the weight resting on his back, but rather the POWER to lift up heavy hearts."

Michael Sutton


My passion for health and fitness has always been a driving force behind why I became a personal trainer. However, the longer I have been in the industry I have realized that the greatest gift that I can give to my clients is ownership of their happiness. Not just in health and fitness, but in every aspect of their life. It is my mission to continue to educate both myself and my clients in every aspect necessary to elicit life changing results for those I care for.

As a fitness competitor and former athlete, health and fitness has always been a part of my life. However, it wasn’t until my time as an ICU Nurse that I was able to experience firsthand how impactful poor lifestyle decisions can be on both the quality and longevity of your life, but on family and loved ones left to endure the aftermath. Having seen this cycle happen again and again, I felt that it was my responsibility to do more, to help those in need, and to educate those I care for to be proactive with their health, rather than reactive. 


Sixth Union Mascot

As the "Gym Dog," I pride myself in making sure that everyone has to pet me as soon as they walk in. I love treats, belly scratches, and sitting as close as possible to you (to watch your form of course). Most of all, I love being told that I am pretty. It is my job to make sure you forget about all the other stressors in your life so that you can enjoy every moment of your training session from the second you walk through the doors until the time you leave. 

Unfortunately I am not available to schedule with at this time, but I'll be sure to welcome you at your intro session!
