Mary Kelly, CPT

Having trained as an elite athlete in wrestling for 20 years and then focusing my attention to the fitness and health culture I have developed a desire for improvement and wellness. I began Personal Training in 2012 with the addition of coaching CrossFit in 2015.

Everyday we learn more about our bodies, nutrition, environment and the interconnectedness of all that we think and do. The results of our choices now, impact our present and future health. We all have the ability to make adjustments that can truly affect longevity and quality of life. By providing useful tools I'm excited to assist in altering conscious results, empowering you to reach your highest potential.

Wanda Rowan, CPT, Silver and Fit Director

As a certified personal trainer and Silver and Fit instructor, I am dedicated to helping you condition yourself  for the life you want to live. After 3 decades working as traveling  independent software consultants, my husband, John, and I had a goal to return to work we loved. I volunteered for animal & marine causes including water safety during triathlons, worked as a software consultant, bookkeeper, wild dolphin swim guide, and then began volunteering to spot the elderly during a fitness class- where I decided to return to fitness. I started lifting weights in high school, and in college, I cross-trained 5-6 days a week: strength training, cycling, aerobics, & jogging. I hadn’t realized how much I missed all the action! So, training & certifications followed & here I am… dedicated to helping you condition yourself for the life you want to live. Let’s go!
