RET Physical Therapy has provided a successful aquatic physical therapy and rehabilitation program at the Aquatic Therapy Center at Mercer Island since 1987. Our experienced therapists have developed specialized and individualized programs that take advantage of the many benefits of warm water therapy.

Aquatic Physical Therapy allows people of all ages and levels of function to reach their goals, and return to what they love to do. For those with difficulty moving, water offers gentleness that provides reduced stress on joints and muscles; great for post-operative joint replacements.

For strengthening and balance, water’s resistance can develop the conditioning necessary to return a seasoned athlete back to their sport. It also gives confidence back to those who want to return to a more active lifestyle.

Unique to the Seattle/Eastside region, our aquatic physical therapy pool offers a combination of a warm water environment, as well as both shallow and deep ends. Shallow water allows successful treatment, even for those that are not comfortable with swimming. If using the deep water is possible, this environment can reduce compression on joints and assist greater muscle relaxation.

To schedule an appointment or for questions, call 206-230-9613.
