Meet the Staff


Alisa Eischen

DPT and Owner

Alisa Eischen, founder and owner of WaveFit, has been a practicing physical therapist specializing in orthopedic disorders since 1991. She was a volleyball player for the University of Southern California (USC). During her athletic career she sustained 6 knee surgeries.  Through both her professional and personal experiences, Alisa has developed an appreciation for the benefits water exercise offers in pain reduction and injury recovery.

During her work as a clinical faculty member for the USC Division of Biokinesiology and Physical Therapy, Alisa frequently used a warm water therapeutic pool in treating patients at Orthopaedic Hospital. The pool proved to be highly beneficial to people with a variety of issues ranging from post-joint surgery recovery to pain management and preventive care. Later in her career as Director of Physical Therapy at Torrance Orthopaedic Sports Medicine Group, she brought the benefits of aquatic therapy to patients by renting a pool at South Bay Aquatics.

Alisa is an avid local South Bay surfer who also enjoys bike riding, skiing, and traveling to surf destinations with her friends and family. Alisa is passionate about bringing the benefits of both land and aquatic based physical therapy as well as aquatic exercise to the general public in an accessible and affordable way.
