Our Team

Megan Sullivan

Active in sports & recreation since childhood, Megan channeled both her love of movement and instruction into a BS in Exercise Science and subsequent Masters in Arts & Education in college.  After 5 years teaching in the school setting she decided to stay at home to be with her kids.  During this hiatus she took her first pilates class from Sheila Grace at then Demi-Bar Pilates and fell in love with how pilates could strengthen, lengthen & tone the body.  Realizing she could merge her two passions of teaching and movement, she started instructing Demi-Bar classes at Energie while completing both Mat & Reformer certifications from Balanced Body.

A natural teacher, Megan is thrilled to be in the studio as now co-owner, bringing her athletic and creative take on traditional pilates to clients at Energie.  She enjoys a fun, fast-paced class that challenges clients to be better than they think they can and loves that clients expect nothing but the best from her.

Outside of the studio Megan enjoys taking other fitness classes, a good trip to Napa with her husband, LaCroix & any kind of chocolate, and cheering on her kids Kieran, Mia, Calvin & Ella at the ball field, dance studio and hockey rink.

Tifani O’Rourke

After working as a trader for a large Wall Street Bank for 12 years, Tifani left the industry to raise her young family.  In 2011, she moved back to the Hinsdale area and began working for then, Demi-Bar Pilates, as a way to have a small amount of “adult” time while also incorporating her love of exercise.  In 2013, Tifani became certified in Pilates and has been teaching ever since to clients at what is now Energie Pilates.  In early 2018, Tifani became part-owner of Energie and loves that she can further the vision of bringing contemporary Pilates to the suburbs of Chicago.  Along with Megan Sullivan, she hopes that more and more people of all ages, sizes and gender will continue to discover the amazing benefits of Pilates. Tifani and her husband Tim manage a household of three kids, and their goofy dog Louie. Outside of the studio, Tifani loves to travel, hang out with her friends and family and a good adult beverage.
