grew up outside of Pittsburgh, PA and was very active in dance and sports throughout her school years. But after college she found herself in a desk job with constant aches and pains. Based on the recommendation from her doctor, Julie started taking classes with Katie Thornhill at Personal Pilates Plus. Seeing and feeling the functional benefits of Pilates, she decided she needed to learn more and bring those benefits of Pilates to others.  “I want to have the ability to do all of the things I love until my dying day – I want to make sure I can still hike with my dog, dance in my kitchen, and travel without limitations – and I want others to be able to do that too.” Julie received her Comprehensive Teacher Training certificate from BASI Pilates and is also TRX certified.

Colleen Riordan

was originally drawn to yoga in 2009 for its physical challenges, but after several years of practicing she fell in love with the additional energetic, emotional, and spiritual benefits. It was her desire to continue the exploration of yoga is what led Colleen to Costa Rica for a 200 hour Yoga Teacher Training. Working full-time as a Licensed Clinical Social Worker in a hospital Emergency Department, she fully understands the chaos that is everyday life. It is because of her professional experiences that she emphasizes the importance of MAKING the time to prioritize health and wellness. Colleen prefers to teach with music, dharma, laughter and a light-hearted approach, while mindfully flowing through a vinyasa. For Colleen, yoga continues to  be a constant reminder to stay present, open, and breathe through every moment that life presents. Whether professional or personal, her passion is to inspire those around her to live a more present and meaningful life. Namaste.
