Meet the Owners

Jenny Sampson

Jenny has  spent the last 20 years looking for the perfect workout. She tried many gyms - from the big gyms to the smaller specialty gyms and everything in between. She tried working out alone and in classes. But it wasn’t until CIRCUIT (now EVOLVE) that she realized how fun working out could be. She loves the music, the energy, the camaraderie. She realized she is so much healthier than 3 years ago when she started these workouts. When she heard the business may close, she felt like she had no other choice but to step in and purchase it - particularly knowing there wasn't anywhere else in town that provides this workout and the friendships. 


Jenny is a native of Sylvania and, after living out of town, came back here to raise her family including her 2 teenage sons. She has been very involved in the schools and the hockey programs over the years. Jenny feels very fortunate to have found a gym that she loves in her hometown! And even more fortunate to have the opportunity to evolve it into something even better!

Libby Langenderfer

​​Libby has always been interested in fitness. Being involved in sports growing up - soccer, softball, gymnastics, cheerleading - helped form her love for being active. This athletic lifestyle eventually morphed into a degree in Exercise Science. Libby was a collegiate cheerleader and then spent 7 years as the Head Cheerleading Coach at the University of Toledo, where she also received her MBA.


It wasn't until after the birth of her daughter that she found herself searching for the perfect place to sweat it out to reap both the physical and mental benefits. Libby is passionate about setting an example of positive body image and the importance of fitness as a lifestyle. Fitness should be fun; not something you dread! Libby understands that sometimes you only have 1 hour away from your family, your responsibilities, your life. EVOLVE is committed to making sure that time is worth every moment and spent helping you to realize and become your best self!
