I came to Longevity Performance Institute after dealing with persistent back pain that was keeping…read moreme from moving, exercising, and working out the way I wanted to. I'm a Kaiser patient, and unfortunately my experience with Kaiser physical therapy did very little to improve the problem. I eventually went to another outside physical therapist who helped quite a bit more, but I still felt like I had plateaued and couldn't get myself back beyond about 90%. I found Longevity through Instagram and decided to take a chance. I generally hate going out of network because I'm already paying for health insurance and the additional cost can be hard to justify, but in this case I'm extremely glad I did. Gary specifically was a perfect fit for me. He was attentive, thorough, knowledgeable, and actually took the time to understand what was going on rather than just running me through a generic set of exercises. The experience was night and day compared with both Kaiser and the other physical therapy I had tried. Over time, Gary developed a program that got me back to well over 90%, but more importantly, got me moving, exercising, and working out again--which was exactly what I wanted from physical therapy. I also felt like I understood my back better and had a plan for continuing to improve rather than simply hoping the pain would go away. Their new Orange location is great too. The facility is really nice and the entire experience has been excellent. I almost wish I had more back problems so I could keep getting treated there. Almost :) I would absolutely recommend Longevity, and Gary in particular, to anyone who has gone through traditional physical therapy and feels like they've plateaued or aren't getting the individualized attention they need.

Dr. Gary resolved a nagging hip pain I've had on and off for years due to overuse. I've seen PT's in the past and they've all said the same things: "stretch your hip, work it out a little more, etc." and none of them every found the root cause. From the first session, I could tell Dr. Gary was different. He looked at my issue holistically and focused on the bad ankle on the same side as my bad hip. After that first session, I haven't had hip pain and for the remaining sessions we were able to focus on ankle mobility to resolve other issues related to it. I can finally enjoy playing basketball without any pain again! Thanks Dr. Gary!

After being placed on hold for quite awhile, they found my referral and said that I needed to be assigned to a provider and will be called back in 24 hours to schedule appointment. No call back, so I called to follow up today 9/11 and was told they couldn't find my referral again. Gave my info then the receptionist rudely asked if I had seen pain management before, which I replied, yes for my back. She said I need to submit my records for any pain management because the doctor needs to review and approve me before I can get an appointment. I said they need this even though it's for another part of my body? She said it doesn't matter, they need to see everything. At this point, I was so frustrated because she never confirmed she found my approval and added a new hoop to jump through to see if I will even be "approved" to get an appointment for a consultation. This is absolutely ridiculous and I just said thank you and hung up. Good luck getting past the front office to even get a consultation!

Five years of pain and disability were finally explained when another surgeon had to completely…read moreremove and reconstruct the hip this doctor put in. The original implant positioning was dramatically outside specifications--confirmed by imaging and the actual findings during revision surgery. Even worse, the measurements documented in the original operative report were contradicted by the actual imaging and surgical findings. This isn't speculation or opinion. It was proven by the surgeons who had to fix his work. Both hip components were put in incorrectly and needed replacement. He left me with a disaster that required major reconstructive surgery and a brutal recovery. Five years of pain because this doctor couldn't do the job correctly and couldn't accurately document what he had done. Incompetent, dishonest, and completely unacceptable. Stay away from this doctor.

It had been quite some time since I last saw a chiropractor, so I was long overdue for a visit…read more I've been to a handful of chiropractic offices, but this one is truly something I've never seen before. The office is so sleek and modern--I couldn't stop gazing at the beautiful interior. Whoever designed it deserves multiple gold stars! (lol) Although the initial price for the intake appointment is a little higher than at other offices, Dr. Gan was very thorough in explaining the type of care I could expect. Despite also working in the medical field, I still get a case of white-coat nerves around new doctors. Dr. Gan--and most importantly, Ruby (the office mascot )--were great at easing and calming those nerves. My body has been through a lot over the years, and I have to say that the few appointments I've had have done wonders for my daily aches and pains. Here, you can tell they don't provide subpar treatment just to ensure repeat visits; they genuinely want their patients to get better and return to full capacity. Dr. Gan even provided me with exercises to help address potential problem areas in the future. If you're still on the fence about visiting this office, cast your worries aside--you'll be fully taken care of. (:

It's been a long time coming. I've been seeing Dr. Jason…read moresince 2018, back when I was completely lost and hopeless about my back pain. I have a bulging disc in my L5-S1, and at the time, even walking hurt. Finding him was the turning point--not just for my physical health, but for how I approached investing in myself. Jason goes above and beyond in every session. He doesn't just crack your back and send you on your way. It's a deeply personalized mix of deep tissue work and chiropractic adjustment (no electric machines or cookie-cutter routines here). He listens, adjusts based on your body's feedback, and truly cares. Over time, he became more than just a chiropractor--he's been part healer, part therapist, and part miracle worker. Honestly, I was hesitant to tell people about him for years because I didn't want him to get too booked up (selfish, I know). But now that I've graduated from chronic lower back pain and can finally be active again--including picking up cardio--I want people to know: if you're struggling, this place can change your life. I've tried everything from acupuncture to other chiros, and nothing compares to this level of care and impact. Trust the process. Expensive, yes. Worth the investment? Absolutely!!! Now, of course, I've managed to mess up my neck--so the work continues! But I know I'm in the right hands.
