Major continuity of care problem, please call your insurance if you are having problems with Active Marin PT switching out insurance rapidly at the end of 2025 or billing you a ton for appointments you booked before 12/28/25. I learned this behavior is not allowed and violates both patient notice requirements as well as Continuity of Care laws and No Surprise laws in the state of California. Forcing a post-surgical patient in severe pain to make a rushed financial decision at the front desk is considered administrative coercion and poor medical ethics. I had foot surgery in mid November and was referred for post-surgical PT for hip and low back at my 12/22/25 follow up with my surgeon, due to issues that developed from an uneven gait in the walking boot. I contacted my insurance for referrals and was referred to Active Marin PT as well as a few others that were IN NETWORK. I was in pain and not sleeping well, so when I called Active Marin PT on 12/23/25, and was booked in for eight appointments beginning 12/29/25, I was very relieved. In my booking call, I provided my insurance information and Active Marin PT confirmed they were IN NETWORK. I showed up, in pain, on 12/29/25 and was told verbally that Active Marin PT had ended their contract with my insurance the day before, 12/28/25, but Active Marin PT would file something called a "gap form" on my behalf to bring their services back IN NETWORK. I was very confused as I had been booked for eight (8) appointments before they ended their contract on 12/28/25, and because PT was part of my post-surgical care. And I had made sure with Active Marin PT that I was IN NETWORK. I was induced to continue with care because Active Marin PT stated a plan (the "gap form") to deal with their contractual changes so my services would be covered In Network. Importantly, no one from Active Marin PT contacted me BEFORE of my appointment to explain they had cancelled their office's contract with my insurance (Blue Shield of CA, not a small provider) and obtain my consent to different charges or give me alternative options. I was instructed to keep my three appointments that week and wait out the gap form, and frankly I was in terrible pain that was making it hard to walk, and needed help at that point. I have since learned that the medical provider must give written notice to all patients when a master insurance plan is changed. I also learned that the Continuity of Care doctrine means my care continues for a period of time at In Network rates due to the booking date of 12/23/25, and I learned about the Post Surgical Care laws. Both laws disallow Balance Billing, or upcharging the patient to enrich the medical practice above what insurance allows. I followed up daily on the "gap form" both with my insurance and with Active Marin PT; after the first week (3 appointments) I became concerned about the lack of progress and I cancelled the rest of my appointments. The reception did not seem to have a handle on when or how the gap form might be resolved. I also asked how billing was going to be handled and no one seemed to know. I moved on to an In Network PT who is great, but I had to wait a while to get in for care. Active Marin's behavior cost me additional time in pain. Flash forward - not only did Active Marin PT NOT bill for the three visits at In Network rates ($15 per visit for me, total $45), they Balance Billed a total of $590 for three appointments. Before I knew the laws, I offered to negotiate the bill. Per my insurance, these appointments would have cost me $15 per, or $45 total. I offered $250 (5X what my bill would have been to try and be fair) in resolution. While I understand business contracts can change, Active Marin PT owed me full and complete disclosure of this change BEFORE booking me in for 8 appointments, taking me on an emotional roller coaster while in pain, confusing me with insurance jargon, and forcing me to start my care over, all while Balance Billing and violating California Continuity of Care Laws and California Post-Surgical Care Laws. Active Marin PT refused to even discuss the problem or work out a solution with me, instead inserting their billing coordinator into a quasi-lawyer position to go back and forth with me. It is important for the community to take extra steps with this business and triple check insurance contracts have not changed before each appointment or risk expensive and fake Balance Bills and a dismissive and rude attitude. If this happened to you, please file a complaint with your insurance company so you do not pay false and expensive Balance Bills like I did. I am out $590 and a lot of headache due to this bad behavior. read more

They booked me a last minute consultation, and even though I decided not to move forward due to cost, they decided to charge me anyway, which came as a complete surprise on my credit card statement. I found this to be very dishonest and scammy. read more

Cynthia is absolutely incredible! She has so much experience and knowledgable with upper body pathologies and just an overall WONDERFUL physical therapist. She is an equal part in my condition as my ortho surgeon!!! She is also very kind and listens. After months of shoulder/neck pain, she's giving me hope that I may really resolve this issue with her!!! read more

Super impressed with Active Marin Physical Therapy. I elected to go there based on Yelp reviews and have not been disappointed. I went in for lower back and sciatica pain. The physical therapists are all highly skilled, professional, and knowledgeable. I love the online system for tracking exercises and watching videos to ensure you're doing them correctly. I've been very pleased with Ming & Nikki. read more

Doesn't take Department of Labor OWCP claims for physical therapy. Find another place for workers comp physical therapy.

I've been working with Maggie T. for several months following my shoulder injury and surgery. She has been very professional, encouraging and always knows how to move my recovery to the next level She is efficient in the use of our time. I find her always prepared for my visit as if I'm the only patient that day. The office is equally professional and supports her work seamlessly. Marcia R. read more

I had shoulder surgery in May 2023 to repair a completely torn rotator cuff and a bicep tear on my right arm. Two weeks after surgery I started PT. At the very beginning I could hardly lift my arm. Now 4 months later my right arm moves almost the same degree as my left (5 degrees different right now). Pain was quite intense the first month, but working with Andrew Phong was excellent. He was great at slowly bringing me along and back to some sense of normalcy. I highly recommend both Andrew and Active Marin if you are in need of physical therapy. I saw one comment about billing. I have not had a problem. I'm nearing the end of my insurance coverage and they have been good about paying attention to it. I'm also pretty much at the end of needing further PT attention. I never had any problem with my appointments. read more

After a total hip replacement, I had the pleasure of working with Maggie. She was patient, very professional and knowledgeable. At each session, she was thorough in evaluating my progress and recommended progressively more difficult exercises to work on at home. I am grateful for Maggie's excellent help on my road to totally regaining my strength. read more

Unfortunately, I have need more physical Therapy This time I was assigned to Sam Quinby He is awesome, did a terrific job with guiding me. Excellent team, shout out to Sam!! read more

I have been to a fair number of physical therapists in Marin for a torn rotator cuff, often with mixed or outright unsatisfactory results. Then I was referred to Cindy and Active Marin. They are the real deal. The level of of expertise and care is unrivaled in my experience. read more

Active Marin has a great, caring staff who are doing their best to help patients heal. Their team is very qualified. I recently had trouble getting my regular appointment due to overbooking and the owner/manager took care of me and got me back on track. I recommend them. read more

I've received PT for 17 years and have been in regular pain for 6 years. I've never received PT like at Active Marin...really caring, thoughtful, helpful, with great referrals that resulted in both identifying a serious (thought treatable) physical problem that resulted in better treatment and pain free for the first time. Their experience and sophistication took it levels above the 'cookie cutter' approaches I experienced for years without much help. All PT should be like Active Marin but they're the only ones I've found at this level of care. I'd give them 10 stars if I could read more

Cynthia Rose Koch expertly guided me through rehab for two knee replacements and had me back out hiking on my beloved trails of Mt. Tamalpais in record time. She is incredibly knowledgeable about the mechanics of the human body and knows how hard to push you 'just enough' so that you rehab from surgery at the optimum pace. After enduring several years of osteoarthritis that severely limited my ability to walk, my surgeon provided me with new knees and Cynthia showed me the way to retrain my legs and feet on how to walk normally again, how to strengthen my muscles, and how to ensure that my different body parts were working together in harmony. She really knows her stuff! I enthusiastically recommend Cynthia without hesitation for all your physical therapy needs. read more

Excellent and experienced physical therapy practice. I visited Active Marin with hip pain which developed due to my workout routines. It was amazing how quickly my therapist was able to reduce pain and increase mobility. I am back to my intensive workouts and am back to running. I can't thank them enough. read more

Very bad customer services. They billed me even if I cancelled an appointment in their 48h windows. I DO NOT recommend this practice.

I am so grateful for the help from Hanna at Active Marin in helping me recover after a trail running injury had caused persistent knee pain for months and wasn't improving. She was very thorough in her analysis of the issue and put together an easy to follow training plan that started immediately helping. The knee pain is now gone and I also feel stronger and more balanced than before. I was able to run best ever half marathon with a time of 1:21. I also ran my first Marathon a couple weeks ago and reached my goal of qualifying for the Boston Marathon. read more

Love Hannah my physical therapist, she's very patient and caring, obviously knows what she's doing. She's really helped me with my lower back and wrist that resulted from a recent car accident. I'd say within a month I started to feel 100 % better. Her exercises are comprehensive and easy to do on a daily basis. I only need to see her once a month now, and it's only been 3 months since the accident, that's pretty impressive. Thank you Hannah! Also, must mention that everyone at the front desk, including Charlene and Sean are a breath of fresh air. They make the visits so much more pleasant and inviting. A really great place to spend at to heal. Thank you guys! read more

I highly recommend Allen at Active Marin. He is very knowledgeable and has helped me greatly recovering from my hip replacement.

Active Marin PT, and specifically Hanna Olson, is AMAZING! Among the several physical therapists I've seen over the last 20 years, Hanna has been the MOST effective at resolving my various issues and getting me back to balance and health. I'm so grateful for her patience and gentle encouragement as I moved from injured to strong under her guidance. The initial goal was to strengthen my shoulder, hip, and lower back so that I can do yoga, and I'm thrilled to say that I achieved this goal and am setting new fitness goals! Active Marin implements all the hygienic practices to provide a safe setting during these COVID-times, and the staff are all professional and courteous. Highly recommend Active Marin and definitely see Hanna! read more

I cannot say enough great things about the team at Active Marin. The front desk staff is friendly and professional and the PTs there are extremely knowledgeable. I was lucky enough to work with the owner Cindy and PT extraordinaire David. I came to see them after less then stellar results with another PT group (six months after surgery to repair my Achilles tendon). They gave me a full assessment and because of their experience and expertise were able to uncover some issues that were impairing my recovery. I am so glad I worked with Active Marin. I don't know where I would be without them. read more

While I'm still in recovery, I'd like to write a note about how amazing Laura is. I have a complicated pelvic issue which has progressed through my pregnancy and post delivery. Laura provided me some critical mobility alternatives during my pregnancy which really made a huge difference in my pain. Post delivery, I've seen Laura 1-2x a week and am slowly seeing improvements. Laura is extremely competent, provides me with education on my situation, what to expect with progress, and is incredibly patient and reassuring. She is warm, empathetic, and also pushes me. I couldn't recommend her more :) read more

I recently visited Active Marin for a pinched nerve in my hip. Kelly, the therapist who treated me was fantastic. She listened to me and gave me all sorts of exercises to do. I am happy to say I am pain free! I've been to a lot of physical therapy clinics in or near San Francisco over the years, but I really liked this place. It's a great location with easy parking, and a friendly welcoming staff. All of the therapists seem really knowledgeable and have their own area of expertise. I don't think you can wrong with seeking care at Active Marin. read more

I'm writing this on behalf of my godmother, Judy Castillo, who had such an amazing experience with Kelly Knapp that she needed to find a way to leave a review even though she doesn't have an account. Kelly was not only kind, thoughtful and an expert at her trade as a therapist, she actually directed Judy to a specialist after assessing her needs. Meaning less sessions for Kelly but more specific care for Judy. She went out of her way with details and was just so professional, Judy will forever be impressed and grateful for her kindness and knowledge. "I wish we had more people like her. Thanks a million for your outstanding service. Keep it up!" read more

Go here, do the work, get better. I've gone to Active Marin for a few issues over the years, but recovery from a broken pelvis in March required a lot of skill and work. Cindy had incredible ability to observe and know what needed work when. The ongoing PT program helped me re-develop flexibility and strength as I recovered from crutches to walking to riding and finally back to running the trails. It's been a long road, but I would encourage anyone who needs specialized attention from an incredible team of PTs (shout out to Justin for help with the shoulder a few years back) to try Active Marin. Thanks!! read more

Thank you for great job . The receptionist and Hanna were so helpful . I am very pleased.

I am a very active person and started having knee pain. I went to Active Marin PT thinking physical therapy might help. I was very impressed! Cindy took video of me running on a treadmill to look at my technique and was able to determine a muscle imbalance that was the cause of my knee pain. She gave me manual treatment and also gave me exercises to do at home. My knee pain was gone in a few weeks! read more

Hanna is a terrific physical therapist. She listens and works out a program catered to the individual. All of the staff are extremely professional and helpful with scheduling, etc. read more

Active Marin is fantastic! I was trying to find a physical therapist and most others have months long wait periods. I was able to see David and he immediately had a plan for my injury and has been immensely helpful in getting back to hiking and running again. Thank you! read more

Active Marin has been a lifesaver for me. Referred by my orthopedic doctor, I found Jenni Someillan, PT to be a thoughtful and skilled therapist in helping to unlock my seriously "stuck" pelvis. The pain in my right glute was very severe and Jenni led me through some stretches to do at home. Returning 2 days later she did some resistance moves that gave me almost instant pelvic movement. More stretching at home, the next appointment and some traction in a table this morning, I have even more relief! The Active Marin PT studio has a pleasant relaxing atmosphere, friendly and small, easy off street parking. Across the street fro the Miller Ave Whole Foods. Friendly front desk staff. Jenni (and owner Cindy) have made such difference for me. Their expertise is giving me confidence that I will continue to regain my stability and flexibility. read more

Avoid coming here at all costs!!! While the employees are great the shrewd owner of this company, Cindy, is a horrid business woman. She will bump a post-surgical Medicare or blue shield patient off her schedule to make room for a self pay patient simply because they pay more than Medicare. And even if you get an appointment on the books, Medicare patients wait 2x longer then self pay patients! She also seems to have a constant revolving door of employees (RED FLAG!) DO NOT COME HERE!!!! read more

I love this place! Front desk reception staff are warm, effective and fun. My previous PT moved away so when I needed some help I was referred to David by a friend. He is great! He gave me a thorough assessment and then gave me several stretching exercises which have helped my tight hip joint. Now I just have to keep this up at home! read more

Neck sprain, Cindy and Andrew examined and recommended a series of neck exercises. Exercises worked well, and no more strain! Comfortable, no pressure, very professional environment. Highly recommended. read more

I have gone to AMPT for several injuries over the past few years. Having raced Mt bikes for many years and continue to live a very active lifestyle still riding Mt and road bikes as well as surfing and stand up paddle hiking ect.. Going into my 40's has for sure had some challenges with repetitive use injuries and muscle strength flexibility imbalances . Everyone that works at this clinic is top notch and super professional. They work with you 1 on 1 and understand that each person is unique. They concentrate on you with kindness patience and dedication. They utilize a huge amount of knowledge and collaborate amongst themselves to make sure they are on your team and get you on a path back to recovery and allow you to continue to follow your passion. read more

Outstanding! I have worked with many physios over the years, but the team at Active Marin were one of the best. Hannah and Laura worked for 4 weeks with my 15 year old son who was recovering from a soccer knee injury. They were "firm but fair" with him with regards to his return to play protocols (much needed!), really "knew their stuff", and got him rehabbed on time as forecast. Communication was excellent throughout, and continuity and online exercises were well managed through their "patient portal". All in all, great experience and highly recommended. read more

This team of physical therapists continue to change my life. They eliminated my daily chronic low back and neck pain, which prevented me from doing so many things. I saw multiple therapists there and they were absolutely fabulous. A special shout out to Victoria for being such a beacon of light and positivity, to Charlene for running the airtight ship like a #girlboss, to Jenny for her amazing intuitive and practical physical therapy/healing, and to Justin for his extensive knowledge and can-do attitude that helped me work through the hard days of recovery. What an amazing team! The office's professionalism, integrity, and charisma make appointments something I look forward to. read more

Justin Newcomer does it again! He put this old man together again. I walked in almost 82 with bones to match and walked out after my treatments feeling like 35. He knows what "buttons" I should be pressing. He has a great style, not demanding but guiding, coaching and encouraging. I almost can't wait to see him again, but not professionally. i read more

We have gone to Active Marin and seen several PTs for various sports-related issues. They have universally been excellent. We especially love Justin, who has been truly a cutting edge resource for baseball specific development and bodywork. We love Active Marin! Charlene is also super helpful in getting us in. Highly recommend! read more

I highly recommend Active Marin! I worked with Stuti who was extremely knowledgeable, patient and friendly. I came in with persistent yet changing foot pain and Stuti took the time to listen to my full experience and make recommendations. As my pain changed over the weeks that I was seeing her, she adjusted my treatment plan accordingly and never stopped investigating to get to the root of my problem. She was easily accessible and quick to respond to my questions and I appreciate everything she did to help me on my healing path. Right from the start my experience with Active Marin was positive. When I called to make an initial inquiry, Cindy called me right back with a ton of useful information about which members of her team specialize in foot care and who might be a good fit for me. I also greatly appreciate the help Victoria gave me while trying to schedule an appointment and figure out what my insurance co-pay would be. I'm very grateful for the team at Active Marin and would highly recommend them to others. read more

I came in needing PT for tendonosis in my elbow and a slap tear in my shoulder. Their staff was very friendly, competent, and welcoming. There is ample parking at the location, and the facility was clean and efficiently organized. There is plenty of room for mobility work as well as a good layout for an appropriate level of discretion. Even when they are busy, they try as hard as possible to work with your schedule. The staff are very good with contacting you if you are on the waiting list for an earlier appointment. Seena was very knowledgeable, considerate, and a great listener. She helped me overcome my injury limitations and get me back into a normal lifestyle. read more
