Movement Source Instructors


Donna D'Angelo

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.


Jennie Doran

Jennie first started practicing Pilates at Clasique Acupuncture and Pilates Studio in the mountains of Western North Carolina.  After her first lesson she was hooked and knew that she wanted to bring this grounding and empowering practice to others.  After years of taking private lessons, group lessons, and attending weekend seminars she relocated to Philadelphia.  One of her first moves when she arrived was to enroll in the Drexel Pilates training program.  


At Drexel Pilates Jennie was able to dive deeper into the work.  The program’s emphasis on knowledge of anatomy, the importance of breath, and other supportive instructional methods helped her to develop her skills as a thoughtful and positive teacher.  


Upon graduating in the summer of 2021 she began teaching in Philadelphia.  She loves teaching and finds great joy in seeing her clients gain strength and confidence through movement.

Kate Seethaler

Kate Seethaler came to Pilates in search of a movement modality to support her dancing and dance teaching. As an unabashed nerd, she became hooked on the specificity and infinite possibilities that Pilates offers to all bodies. Kate received her full mat and equipment certification through InBalance Pilates at Aldrich Pilates in New Haven, CT.


In addition to teaching at Aldrich Pilates, she has taught this method at The Taft School, City Fitness, The Sporting Club at the Bellevue, as well as to City of New Haven employees and public school teachers. Kate also currently works as a dance teaching artist, choreographer, performer, and arts administrator. She is extremely excited and honored to join the staff and clients at Movement Source as it feels like home in a great many ways!
