Marni Larkin, Physical Therapist, Orthopedic Clinical
Specialist (OCS) + Studio Owner​

Marni Larkin is a board-certified Orthopedic Clinical Specialist. Over the years she has worked with a varied clientele, from Nursing Home populations to Dancers, Athletes, and people suffering with Chronic Pain. She completed the Feldenkrais Method training in 1998 and studied various forms of yoga, in particular Iyengar and Jivanmukti. Her background includes competitive gymnastics, running, and karate, and she is an avid snowboarder.  Her most recent focus is understanding pain science principles and relationships to graded exposure and graded loading protocols. GYROTONIC® methodology is a great fit for that and  Marni continues to see remarkable results for her clients/patients using this focus.


"I made a conscious decision to go this route after spending 15 years+ in various fields of Physical Thearapy practice, figuring out what really worked in the long-term for people. I am committed ultimately to giving the client tools to develop preventative health practices in as straightforward a manner as possible.”

Christy Ambrosini

Christy is grateful to share her passion for the Gyrotonic system. She completed her B.S. in Human Biology at the University of Southern California.  While competing in track and cross country at USC, she sustained injuries that sparked her interest in the body's innate ability to heal itself.  Her recovery from injuries has guided her to pursue holistic healing methods to practice herself and ultimately share with others. 


Working as a trainer in physical rehabilitation facilities gave Christy the opportunity to work with a variety of clientele, including people with spinal cord injuries, strokes, and brain injuries.  She is interested in combining multiple modalities to support the healing process, including movement, nutrition, nature, aromatherapy, and meditation.  Christy is ALSO a registered nurse, working in labor and delivery with Northwell.

She is truly grateful to be part of the talented and lovely group of teachers at Gyrotonic Manhasset Physical Therapy and we are grateful to have her as part of our team!
