I had shoulder surgery with Dr. Kantor two months ago and the entire experience has been exceptional. From the first visit, everything was explained clearly and I felt completely safe and at ease. I appreciated the thorough examination, onsite X-rays with immediate results, and a treatment plan that actually made sense. His bedside manner during surgery was wonderful. I was comfortable the whole time and did not feel a thing. What really sets this practice apart is how well it runs. I have never waited more than five minutes to see Dr. Kantor, his availability is remarkable, and there is zero wait time for call backs or refills. I am still in post-op/follow-up and the continuity of care has been excellent. And the team is just as impressive. Karla at the front desk is kind, warm, and so professional, and Alex in the back office is the same. It is a truly professional, well cared for environment. read more

I didn't have quite a great experience like most of these reviews. First thing he said when he entered the room was "stay at home mom" which isn't what I had written down for my profession. I asked why he said that. He answered "because of the age of my children". Strange. His suggestion for my pain I've been having for over a year, was to change my bed (or bed topper) and not workout my lower half for 3 weeks. I wish he would have taken the time to really figure out the source of my pain. I felt dismissed. I got a second opinion. That doctor found that my left L5-S1 disc extrusion contacting the left S1 nerve root. Finally I can find some relief for my severe pain I've been experiencing. He was easy to book with if you're in a bind. read more

Dr. Cantor was so friendly. My daughter was injured with a broken ankle over the weekend and when I called Monday morning, he got her in first thing. He was friendly, the office was welcoming, and he was able to cast her foot right away. It was a bonus that his office is close to our house. I would highly recommend him for your orthopedic needs. read more

I cannot express enough how grateful I am to Dr. Kantor for his exceptional care and dedication with my ruptured achillies. During a particularly challenging time, Dr. Kantor went above and beyond by staying during his lunch break to treat me. His willingness to prioritize my well-being over his own break is a testament to his commitment to his patients. Dr. Kantor's expertise and compassion were evident throughout the entire visit. His genuine concern for my health truly made a difference. Thank you, Dr. Kantor, for your incredible kindness and for being such a remarkable doctor. Your dedication does not go unnoticed, and I am incredibly appreciative of the care you provided during my time in your office. Thank you. read more

After managing to injure both my ankle and my shoulder in July 2025 (overachiever, I know), my first stop was urgent care, where I was fitted with a boot and sent on my way. Next I googled orthopedics and made a few phone calls. Thankfully, Dr. Kantor was able to get me in immediately. Dr. Kantor was thorough from day one. At my first visit, he put me in a cast and followed my ankle closely with regular visits until it fully healed. When I later mentioned that my shoulder wasn't improving, we got an MRI and he told me surgery was needed. I disagreed, mostly because I was hoping it would magically fix itself. He respected that, said "OK," and we tried physical therapy first. Six or seven weeks later of PT, he asked again if I was ready for surgery. I said yes, he had been right all along. My hesitation was never about trust; it was fear of surgery. Dr. Kantor and his staff were patient, supportive, and never pushy throughout the entire process. I'm now 11 days post-shoulder surgery and five months out from the original injury. My ankle is healed, my shoulder is doing great, and while I'm not completely out of the woods yet, I'm incredibly grateful. I'm finally on my way back to the active life I love and I couldn't have asked for better care along the way. Highly recommend Dr. Kantor and his outstanding team. read more

I've had meniscus repair in both knees and should tendon repair. Every time I've come back he remembers to ask about family and is very engaging. Also, with all three surgeries, I have had full recovery. I would refer him to anyone who asks. read more

Dr. Kantor and his office staff are the best!! I came to him with 2 bad knees. He has already fixed one and one more to go. His office is so accommodating. They are very sympathetic to your injuries and accommodate same day appointments. I am sure you all have experienced calling Orthopedic Doctors and they are weeks out, regardless of the situation. Not Dr. Kantor. He and his office staff work very hard to accommodate your needs, so you are not left hanging for weeks at a time. He explains all to you very clearly and thoroughly. One knee down and one more to go. Doing great, thanks to Dr. Kantor and his many years of knowledge and experience!! read more

I had a problem with my knee and I had gone to urgent care. They recommended we should see an Orthopedic doctor. So I went on Yelp and found Dr. Kantor with 5 Star reviews. We were new to Santa Clarita and didn't want to visit our orthopedic doctor in Pasadena. So I called and I was able to make an appointment on the next day. The staff was friendly and I saw the doctor within 20 minutes. When I arrived the staff asked what was wrong and at that time I couldn't walk on my left knee and I was using a walker. The doctor came in to exam me and he told me we needed X-rays. He took me in and X-rayed my knee. He said you have to have a MRI. As he hurriedly walked out of the room. I wanted to ask him what do I do in the mean time I can't walk, I was in pain, he was in a hurry and I couldn't ask. So we called for a MRI, and we were able to get one the next day, which was the day before Thanksgiving. Therefore the results would not get there until the end of next week. I called the office to ask if they had received the MRI and they told me probably not. I insisted that they look because it had been a week. They found the MRI, and I asked if I could come in today. And they said well you don't have an appointment, and I told them your sign on the window says walking are welcome. So they made the appt. For 4PM, the doctor looked at the MRI and saw I had a menicus tear on my knee. So he said let me take another X-ray of the front of my knee. I asked why didn't you do this before. And he said because you were in so much pain you couldn't do it. We went back to the patient room and he told me I can't repair the meniscus tear. Because if I did that you would need knee replacement. Instead I can give you a cortisone shot that should help with the pain. And then each week for 5 weeks I will inject gel shots in your knee. But eventually you will need a full knee replacement. I decided to get a second opinion from my doctor in Pasadena. We made the appointment took the MRI to him and he scheduled me to take care of the Mencius tear. I did a arthroscopic meniscus repair on my knee. In two days I'll be up and walking around. My Orthopedic Doctor told me my knee did not need a replacement. All of this occurred on November 23, 2025 Therefore, I was not pleased with the advice given to me by Dr Kantor, and I do not recommend seeing him. read more

I really wanted to see this doctor for both of my knees. I am a veteran and have struggled with knee problems for years. I just started a new job and wasn't able to take time off and begged for a 4 pm appointment and even asked the receptionist to pls ask the doctor if he was able to work with me for this one appointment. Seemed like they didn't even try to ask him. I brought my daughter to him for knee surgery so this sucks that they are not able to work with situations like this. read more

Dr. Kantor and the staff are great! They were able to see me on the same day (in an emergency) and immediately improved my situation. Dr. Kantor has a wealth of experience and knowledge and explained things to me in an easy to understand way. He listens and asks follow up questions to get to the root cause to treat both the immediate symptoms and the underlying causes. read more

Dr. Kantor answered all our questions. His expertise and demeanor helped our family and our daughter feel very comfortable with the process, beginning to end. I highly recommend him for your orthopedic surgery needs! read more

So, unfortunately I had to have surgery for a ruptured Achilles tendon and I've been waiting out this review just to be sure it was honest and that i got to know the doctor some beforehand. So my foot was basically hanging and no longer attached to my calf muscle because of a basketball accident back in November '22, and I had my surgery mid December '22. It was extremely painful pre surgery. Let me tell you, Dr. Kantor did great! I just started physical therapy now that surgery is done and my cast is off and everyone at PT has been complimenting on what a great job Dr. Kantor did on my ankle! Not to mention I love his dry humor, he's done great dealing with all of my complaining, and I like how honest he is and how he gets straight to the point lol I highly recommend him to anyone needing an orthopedic surgeon :) read more

See all

I would give zero stars if I could. This guy - a doctor my mom has been seeing for years for her knee issues - lead her through an entire process of knee injections (which is fine to avoid surgery) and after the injections, he made her wait a month only to come back and tell her she DOES need a knee replacement but that for some reason he just refused to do it. My mom is a senior and entrusted her medical care with this man only to get dumped by him when it came time to do surgery? Leading a patient through the course of their treatment and stopping at the end? What? It's like dining at a restaurant and right before your meal arrives, they kick you out. My mom is the kindest, most patient person. This man didn't want to do her surgery for some reason. Pick and choose? I don't care the reason, but now my poor mom (who's just trying to be present for her infant granddaughter) now has to find an entirely new doctor through Medicare and go through an entirely new treatment before surgery just because this hack didn't feel like doing her surgery? Sketchier yet, they refused to release her MRI's and other medical docs until they "completed treatment" which is really bizarre. The doctor seemed so nice so this is incredibly disappointing. Can't wait to report him to the medical board as well. It's also extremely weird that he replies to these negative reviews himself and not only blames the patient but also accuses people of libel when they're speaking about their experience. Someone missed their bedside manner class in med school! read more

I'm not sure why these reviews are so positive. I visited Dr. Kantor two years ago for an ankle injury. He insisted on an in office x-ray even though I had one done a week before at Henry Mayo. After reviewing my x-ray and ankle he gave me a Cortizone injection and tried to sell me an ankle brace for $150. Thankfully, I found it on Amazon for $20. He charged my insurance $1000 for a 15 minute conversation, x-ray, and cortisone injection. I'm not sure how they justify those charges. Since then, I went to see The Foot & Ankle Institute, where they told me that I have two torn ligaments. I was very disappointed with my experience with Dr. Kantor . read more

My son dislocated his shoulder riding his skateboard. I went to Dr. Kantor because of his Yelp reviews and I'm so happy I did. He is just the best.

Where do I start? Other than saying thank you Dr. Kantor and your staff (Amber, Amanda, Lorraine, Nathan). Everyone there were very helpful and patient. There were some obstacles I had to go through to finally have my surgery, and I'm glad I did. Every step of the way I felt like I was apart the family. Special thanks again to Amanda and Amber for all they have done for me. I really appreciate you guys.!! I am always greeted with smiles and professionalism whenever I visit the office. If there was anything I needed they were right there. I had a procedure on my shoulder and I am now in recovery. Dr. Kantor made me feel like I was a priority and he made me feel very comfortable. He explained to me in detail what his approach would be step by step, All the while easing any concerns I may have had. His expertise was impeccable and it showed throughout my entire experience. The day after my surgery I received a follow up call to see how I was doing, and how everything went. If there was anything I needed all I had to do was ask. I would recommend Dr. Kantor to ANYONE who needs an expert opinion. He will make you feel like you are in good hands, and will provide a level of service second to none. If I could give them a rating higher than five stars , they would be deserving.!! Dr. Kantor is Awesome!!!

Good people are hard to find, but Dr. Kantor and his staff are grade A. read more

I wanted to thank Dr. Kantor, and his staff for my knee surgery April 4th, 2023. My knee feels great! Walking and riding my peloton only 3 months after surgery, feels fantastic. I had ACL surgery using a cadaver tendon, walked after a week, very little pain. So glad I trusted Dr. Kantor with my knee! Don't hesitate to have that surgery, I put it off for several months, wish I would've done it sooner! Focus PT in Newhall is incredible also! Rebecca was fantastic and so helpful. Like a big family there. Thanks Dr. Kantor! Your the man read more

If you need a Orthopedic surgeon look no further. I was worried about finding the right surgeon to rebuild my ACL. With heavy research me and my wife found Dr. Kantor who handled ACL surgeries for high level athletes. I knew he was the right man for the job! Sure enough we were right. My new ACL is solid and I'll soon be able to get back to doing the sports and activities I love! The staff is very friendly and they work diligently to provide Dr Kantor's patients with proper care and attention. Pre op and post op. They also offer stem cell treatments! Other places do not. read more

I LOVE Dr Kantor and his professional staff. I so appreciate the care and attentiveness each delivers. I Have been a patient at Kantor Orthopedics for at least 7 years. Recently had occasion to go back in today and Dr Kantor greeted me, knowing exactly who I was --rare for doctors--and was ready as ever to help me. I can't recommend him more highly!!! 100 stars, please. read more

My daughter suddenly started having severe back pain and we tried acupuncture, chiropractor but to no avail. We finally decided to get Orthopedic Doctor to find out what was really the issue. Dr. Kantor and his office staff is very friendly and kind. That was a great beginning. We made an appointment and we were seen pretty early after explaining the pain level my daughter was experiencing. We visited the office and Dr, Kantor was very friendly and we had X rays right there inside the facility. Then he ordered MRI for closer look, also pretty quickly. The whole process was lot faster than I had anticipated and we found that my daughter had bulging disk. We received some medication and now we are going to Physical Therapy as directed. The pain level before visiting Dr. Kantor was around 7-8 (from 1-10 scale) but now the pain went down to either 1 or 2. I am so glad I found Dr. Kantor and his staff. Next, I am brining my wife and I will also get more treatment from Dr. Kantor as I realize there is no need to wait but get reliable and expert Doctor's diagnosis to treat the pain and discomfort. read more

Dr. Kantor did such an excellent job on my shoulder surgery a few years ago that I came back to him when I needed surgery on the other shoulder. He does great work, has a great demeanor and really cares about his patients. The office staff are great and have gone above and beyond on things I've needed to provide my employer both pre and post-op. If there was a procedure or surgery I needed and it was something Dr. Kantor did I wouldn't go anywhere else. read more

I've been a patient of Dr Kantor since 2003. Each occasion I've had a joint need more than physical therapy, Dr Kantor has performed the least invasive surgical solution. Whether it was torn meniscus or rotator cuff, I healed quickly and have had excellent follow up care. I highly recommend Dr Kantor and his staff. Friendly, informative and highly skilled with up to date techniques and very little down time after procedures. His sense of humor keeps spirits up even when the stitches come out! Plus, cookies at checkout! read more

I have struggled with a trigger finger for several years. In case you are wondering, a trigger finger is when your finger (or a thumb) gets locked into a closed position due to an inflamed nodule that won't release your finger. It's annoying, painful, and inconvenient because when you have it, it is always in the back of your mind when using your hands. After several tries to treat the problem conservatively, my wife found Dr. Kantor and set up an appointment for me. First impressions, his office staff are efficient, professional, and friendly. Not distant and aloof like many medical settings, but neighborly. Plus one. I was then taken in for x-rays, however, I couldn't have them taken because my finger was locked and I hadn't been able to straighten it for several days (it locked over the weekend). I was taken to Dr. Kantor, and he numbed my finger enough to manually pop it back straight, which was quite a relief after several days of having it locked closed. Plus two. Dr. Kantor gathered my history, and counseled me that another cortisone shot was not indicated for me because of the number I have had in the past, and he recommended a minor outpatient surgery at the local ambulatory surgical center. My problem was scheduling, because I needed to fly out of town in a few days. No problem, Dr. Kantor listened to me and asked his scheduler (Daisy) to schedule me as soon as possible, and that he would do my surgery over his lunch hour if necessary to accommodate me. Because of his caring and willingness to put himself out, I was able to get my surgery scheduled quite immediately, which meant I would get a permanent solution to this problem that had ailed me for years. Plus three. The surgery was uneventful and of course successful. I have since seen Dr. Kantor for two post-operative visits. Today he removed my stitches, and I was pleased to report to him the improvement in my finger, and how appreciative I am. Because I am in and out of town a lot, all my appointments have been made so as to accommodate my schedule. Plus four. Last, let me say that Dr. Kantor is an excellent orthopedist and person. He makes you feel comfortable with his cheerful and humorous manner, and at the same time, he is a great teacher. Every stop of the way, he explained clearly what my options were, what my surgery entailed, and the like. He drew my surgery out (on my good hand with a pen) like we used to draw football plays on the palms of our hands when we were kids. Bottom line, I understood exactly what was going on, and while I was nervous at times, he always went out of his way to make me feel comfortable. Plus five. And that's how you earn five stars, fellow Yelpers. I could not recommend a doctor more highly, and I could not have been more pleased with my experience in this office. read more

Dr. Kantor was an absolute pleasure. I broke my hand and I'm in my thirties. I haven't broken a bone since I was a teen.

I won't go anywhere else now for a broken bone. Thank you Dr Kantor for your professionalism and kindness. read more
