She has completed an Ironman and numerous marathons including the Boston Marathon. Cari fell in love with the Lagree Method because, after years of pounding her body, she welcomed the intense challenge of the Megaformer, without the impact to her joints. Since Cari loves a good amount of heart-pounding cardio, she couldn't launch Studio 3 without adding rowing. She loves creating an environment where all fitness levels are welcomed and challenged.

When Larry is not teaching or working out, he enjoys hanging out with friends and family, shopping and drinking lots of wine.

Born and raised in Cleveland, Natalie spends her free time traveling the Midwest to visit family and friends. If you want to talk sports (particularly Cleveland sports), she is your girl.


Mary Mack

Mary grew up as a dancer in Central Illinois, so anything that relates back to that in fitness is something she can leap in to! She is certified and teaches the Lagree Method on the Megaformer, as well as Barre at Core 3 and is trained in TRX. Her favorite part about teaching is seeing clients’ form improve and watching them get stronger and slower in the movements the more they come to class (her second favorite thing is putting together playlists that will distract them from the shaking)! Outside of teaching, She works full time in digital marketing & is a freelance writer—putting that journalism degree to use for more than just corny jokes every time she puts the “newspaper” move in a routine! When she’s not working or teaching, she loves reading, cooking, Christmas and relaxing with her husband and her handsome and perfect corgi, Dexter.

Sarah fell in love with the Lagree method because it is a high intensity, low impact workout that left her more sore than any other workout she had tried. She knew the Megaformer would challenge her in new ways, and thinks Studio 3 is a great one-stop studio with class options for people of all fitness levels and abilities.
