About Jonathan

My name is Jon Sheppard and I am the owner of GOAT Fitness. GOAT Fitness (Greatest Of All Time) is a private personal training facility specializing in getting you results. Whether you want to lose fat and tone up, build the most muscle you can fit on your body, or become the strongest person in the gym. We design a custom training and nutrition plan that is guaranteed to help you become your Greatest Of All Time.

Our trainers all have unique stories that have brought them to the health and fitness field but all have made it here through passion and a desire to share their knowledge and experience of living a strong and healthy lifestyle. I personally changed my original career as an underwater welder to follow my passion of training/coaching people to become their Greatest Of All Time (GOAT Fitness)

GOAT Fitness's motto is "Passion Breeds Success." This job is our passion and the proof is in the results. We love being strong and living a healthy life. Our trainers give 100% dedication to each individual training client because we want to share our secret to a healthy and positive life. #fitlife
