About The Owner

Kelly Adorno


Movement Source is an intimate Pilates studio located along East Passyunk Avenue in South Philadelphia, that focuses on the individual experience.  The studio offers Pilates teachings on the Reformer, Cadillac, Mat, Chair and Ladder Barrel.  When joining the studio, expect personal attention in private lessons and small group training.

Movement Source is an anti-racist and anti-discrimination organization that provides Pilates/movement for every single body.  Since opening its doors in 2016, Movement Source Pilates Studio has been committed to providing a space where everyone is welcome. 

The studio's mission is to teach each person with acceptance, care and understanding while sharing the benefits of Pilates and movement with the Philadelphia community.


Growing up as a dancer, Kelly always had a love of exploring movement.  While attending Temple University, she was introduced to Pilates and knew immediately that she had to share this incredible method with others.  Since completing Body Precision Inc.’s comprehensive Teacher Program in 2012, Ms. Adorno has enjoyed working with a multitude of people and witnessing the amount of healing the Pilates Method can provide.  

Kelly's teaching technique combines moving, learning, sweating, and laughing.  Constant curiosity keeps her striving for new approaches to traditional exercises in order to mold each session for the individual.  In between working with clients, Kelly can be found at the local coffee shops along Passyunk Ave.  

Meet The Team


Donna D'Angelo

Movement Source


Donna first started practicing Pilates at age 15 after a doctor had recommended it as a way of managing her scoliosis. Little did she know then that it would become a lifelong passion.


She practiced classical Pilates throughout most of her life, but turned to more contemporary approaches when it came to her certification. In 2014 she completed her mat certification through the Kane School of Core Integration, a progressive training program with a focus on biomechanics and anatomy. In 2019 she completed her equipment training through the Drexel Pilates Training Program, under the direction of Jennifer Morley, who studied under both Romana Kryzanowska and Karen Carlson.


Donna’s favorite thing about teaching Pilates is how personal it is. She loves helping her clients learn more about their bodies so that they can make mindful movement choices that make them feel stronger, taller and more energized throughout their day!


Outside of Pilates, Donna comes from a family of fishmongers and enjoys learning and teaching others about sustainable seafood. She enjoys cooking, traveling and playing with her hound dog, Bob.
