Our Mission

To change the world by helping our community to become healthier and happier. We know that when one persons life changes for the positive that they pay it forward and positively impact their friends, family and community. Come as you are, leave fitter, healthier, happier and uplifted.


Jeri is a one-of-a-kind personal trainer. She is the first one who understands my limitations, injuries and really strives to find ways to work thru them without creating more issues.


When I started with Jeri in 2020, I thought I was too old to get stronger. Jeri’s encouragement and constant motivation pushed me to heights I never thought possible.


I’ve tried the fitness thing many many times over the years. At many gyms… And it never stuck. And then after Covid turned our lives upside down, I like many people made a lifestyle change.


I’ve been working with Ashley at Dudas Fitness since May 2020.  While my main goal is weight loss, the strength that I’ve gained is amazing!


My goal when I started was to be able to run again, and I accomplished that last month.


Custom Workout Plans

At Dudas Fitness, everything is tailored to your personal needs. We understand that everyone is unique and generic workouts don’t achieve the same results.

Group Training

There are two group training options: Small Group Training and Semi-Private Training. Both are a more affordable option for those looking to benefit from the attention of an elite trainer.

Support Services

Enjoy a relaxing and therapeutic massage, enjoy a private yoga or pilates session, or attend one of our educational workshops or special events to support you and your healthy lifestyle.

Our only focus is you!

At DUDAS Fitness we provide you
