"Synergy has always been a very helpful physical therapy group. I've worked with several of the therapists there, most recently David. I find the exercises I'm given with the goal of reducing pain and gaining mobility is always a successful outcome. I would recommend Synergy to anyone who asks where they might find excellent physical therapy care. "

"10/10 recommend synergy PT. I have come to Synergy a few times in the last 7 years. Dave and team have created an office of growth, development and healing centered on a culture of family. Dave and his team know how to encourage and push me to the next level of recovery and performance. I would recommend going out of your way to go to Synergy PT over a closer option. It is worth it!"

"I came in unable to walk from a fractured pelvis due to a car accident. I had excellent care from everyone at Synergy! Stacey was my main therapist and she was always conscientious explaining to me which exercises affected which body part. She was excellent at explaining and watched that I did the exercises correctly. After 6 weeks, I am able to walk and on my way to recovery. I highly recommend Synergy, everyone is excellent and personable! Thank you!"

"I just completed 2 rounds of 12 physical therapy sessions with Dave at Synergy for a potentially torn rotator cuff. I am extremely pleased with my progress in the careful and skillful hands of Dave and his staff. Dave Ishii leads/owns a well run, organized and warm PT environment. The facilities are clean and well kept. Each time I walked in the staff greeted me by name and and were always one step ahead of me to keep my exercises set up and my time efficient. Dave is incredibly well versed in all things PT, human anatomy and medical related. He handles insurance companies effectively to support client needs to the best of his ability. Dave is a fantastic business owner and supports his clients and the Huntington Beach community. I have gone to PT at other companies which were fine, but synergy is exceptional! The greatest testimony is the wonderful improvement and understanding I gained of my injury. Thank you Dave and your wonderful staff at Synergy PT!"

"I came to David at Synergy physical therapy a few months ago. I had a major ankle injury in October 2021 that required surgery in February 2022. I was going to a physical therapist for more than a year, that put me through the same basic treatments that were unsuccessful. I was very frustrated. Still dealing with pain and swelling, I was upset because of my limited mobility and strength. David and his teams gave me the help i needed. Now pain-free with minor limitations my strength has increased dramatically. Thank you, Synergy Physical Therapy"

"I came in after an ACL surgery after three similar rehabs (on the same knee) at other therapy places that all resulted in re-injury. After coming here, I have never been so confident in a rehab. My knee feels stronger than ever, and I left with no complaints. The therapists are knowledgeable and actually care for their patients. The aids are attentive and keep the sometimes monotonous rehab fresh and exciting. I’d recommend Synergy to anyone that needs it, athletes or not. Going back to the sports I love has always seemed scary after I finished my rehabs, but now I feel 100% confident."

They were attentive to my goals and worked to develop a plan to allow me to get back to the physical activity I had previously enjoyed. Synergy has a family feel to it and the therapists and assistants who I worked with knew my goals and everyone is caring and kind. They are very attentive and helpful explaining the rationale for the exercises selected and ensuring they are done correctly for maximum benefit. The facility is immaculate - great effort goes into maintaining a safe and environment for the patients and staff.

"I was recommended by my neighbor to go to Synergy for physical therapy after suffering patellofemoral pain syndrome & ankle pain during quarantine after trying to stay in shape. I completed about 2 full 12 weeks sessions there. I can honestly say they took great care of me and taught me great exercises to keep up at home. My knee pain is now minimal and ankle pain gone. Dave & staff were stellar. They were very nice and knowledgeable. Dave ensured I had positive tissue changes before discharging me. I forgot one of my session times and turned out to be 30 min late and they called and fit me later that day without any issues and were very understanding. They are constantly cleaning between patient use and only using every other table to maintain social distancing. I highly recommend Synergy if you need physical therapy."

Also, and probably more importantly, there was ZERO turn over from the staff in the 4 months that I attended there. If you compare that to other PT places that I have been to in the area that is astounding. One place I had a new therapist every 3 weeks for 3 months. NOT THIS PLACE. AWESOME."

I found my physical therapy with David Ishii to be thorough and motivational for recovery from surgery. He has excellent knowledge, which he helps you as a patient, apply to your recovery. I recovered faster than expected and was much stronger after therapy. He is friendly, professional, and he gives you the extra bit of attention that you need to feel comfortable to succeed.

David's knowledge and commitment to the patient allowed me to recover from injury and fulfill my dream of competing in the Olympic Games. They were able to help me recover again, just before the World Championships, where we won the gold medal. I will continue to rely on Synergy as we prepare for another Olympic Games…this time as favorites.
