Simply Fit Fun-2.jpg

who we are

We are Stefanie Sweeney and Danielle Ampolos, and our goal is simple: we want you to be happy and healthy!

We offer a variety of classes, small group training, private fitness parties and events for both personal and corporate settings. Regardless of the setting, we always work to deliver a workout in a very positive and welcoming environment. One of the unique things about Simply Fit & Fun is we are always together teaching! It's a two for one experience! In addition to our classes, we offer virtual clean eating programs, Simply Streaming virtual workouts, specialty events that are unique to Simply Fit & Fun, free child care, and much more!

A decision back in 2014 to partner up and co-teach Zumba® together has evolved into a community and overall way of life. We truly understand and empathize with the struggle to find that work/life/healthy lifestyle balance, and keep that in mind with all that we create in the hopes of keeping you active and happy!

Stefanie and Danielle are both certified, highly qualified fitness instructors and collectively have been teaching for over 15 years. They both grew up in the same home town and have known each other since 2000!
