Trust and confidence.
In patients’ words.

Dr. Bae and the team made an excellent first impression. Dr. Bae was extremely personable, a great listener, and took the time to fully understand my concerns and answer my questions. I especially appreciated his thoughtful approach to shared decision-making—he clearly explained my options without making me feel rushed or pressured. His combination of expertise, compassion, and genuine care made me feel very comfortable and confident in his recommendations.

The staff was very friendly and helpful. I had sent information but forgot to bring my Medicare and secondary insurance card. They knew they could trust us and when we got home we sent it right in. I very much appreciated that. Dr. Millstein was clearly knowledgeable about my condition, New exactly what treatment to give, and was very friendly, And accommodating. I can’t wait for my next joint to fall apart and you can be sure I will come back.

My 80 year old father had been in progressing pain and compromised quality of life due to his knee, but decided he was done suffering and needed surgery. He tried everything, I mean EVERYTHING before deciding on surgery. When he met Dr. Ramkumar, he felt like he was in good hands. From the first consultation, pre-surgery, surgery, and post-surgery appointments, Dr. Ramkumar took ample time and showed patience with my apprehensive parent. Both of my parents are surprised by the quick recovery and ecstatic with the results. A partial knee replacement with full mobility and activity in 2 weeks - wow, just wow! As a child of aging parents, I worry about my folks, but I never felt any concern or doubt in the ability or expected outcome. I feel relieved and am glad that my dad has his quality of life back. He's actually better than ever! I attribute it all to Dr. Ramkumar's skill and ability. I recommend him to anyone that needs a procedure or consultation. He will be honest and tell you the truth. Trust his opinion.

I underwent the FAI arthroscopy with Dr. Ramkumar last month and the recovery has been very smooth. The early results have been great with more range of motion and less stiffness compared to before the surgery. The pain was so minimal after the surgery that I had to actively remind myself to follow the rest guidelines and not bear weight on my joint too soon. My original symptoms were a lot of hip stiffness and limited hip range of motion. I would also notice intense aching with weight lifting, long distance running, and skiing. I regularly stretched and would see physical therapists but my symptoms remained the same. Dr. Ramkumar did an incredible job of running through my symptoms, physical exam findings, and X-rays to diagnose the FAI and rule out other conditions. His discussion of management principles and what surgery and postop would entail was very helpful and reassuring. Also, knowing that he’s done so much of this type of surgery reassured me that my outcomes would be great and recovery would be smooth. He also has a physical therapy team in his clinic that has a structured routine to help improve the recovery process after surgery. I would 100% undergo this surgery with Dr. Ramkumar again and have already scheduled the surgery for my other hip. I would recommend anyone that notices this or similar symptoms to at least schedule a consultation with him to discuss further.

He is very engaged with client. He is confident and have good bed side manner. He is sharp and make quick decision and approach healing in a conservative way.

Shockwave therapy was a game changer for my achilles tendonitis! After dealing with persistent pain that just wouldn't improve, this treatment made a massive difference in my recovery, mobility, and overall pain levels. A huge shoutout to Nurse Practitioner Margot for being so amazing. I was a little nervous for my first session, but she took her time to explain the process and reassured me it wouldn't hurt, which put me completely at ease. Highly recommend this treatment to anyone dealing with stubborn injuries!

If you want the absolute best knee surgeon in Los Angeles, driving to his Santa Monica clinic is 100% worth it.

Dr. Ramkumar helped me during one of the most vulnerable and uncertain times of my life. As a 20-year-old college soccer player, tearing my ACL and meniscus and needing reconstruction with a patellar tendon graft right before my season was devastating. From my first appointment, I knew he was the right surgeon for me because of his dedication to sports medicine, his expertise, and the genuine care he showed throughout the process. He took the time to answer my questions, explain my options, and give me confidence when I was scared about the future. Today, I am 4 months post-op and proud to say that I am jogging again. It’s been an incredible blessing to have my surgery performed by Dr. Ramkumar. The entire team at Commons Clinic has been outstanding. Everyone is professional, kind, and encouraging. I also attend physical therapy right in the clinic, and the experience has been excellent. From the front desk staff to the physical therapists, including Mina, everyone has played a role in my recovery. I am determined to come back stronger than before, and I’m grateful I made the decision to trust Dr. Ramkumar and his team. This surgery has given me a second chance to live an active lifestyle—to run, cut, jump, compete, and do the things I love. That’s something I’ll never take for granted. Thank you, Dr. Ramkumar and the entire Commons Clinic team, for helping me get my life back.

After a frustrating experience with another orthopedic surgeon, meeting Dr. Estess was a complete breath of fresh air. From the start, she took the time to listen and ask thoughtful questions, not only about my injury but also about how I was doing mentally and emotionally. I never felt rushed, and I truly felt heard. Her bedside manner is calm, kind, and reassuring. She explained everything clearly, answered my questions, and gave me confidence and hope during a difficult time. Most importantly, I left feeling that I was in very capable hands. As I prepare for surgery, I have complete trust in Dr. Estess and her team. I am incredibly grateful to have found her and would highly recommend her to anyone looking for an orthopedic surgeon who is both highly skilled and genuinely compassionate.

Dr. Ramkumar and his team are truly outstanding! From the moment I arrived, they made me feel comfortable, supported, and confident that I was in the best hands throughout my procedure. Dr. Ramkumar is incredibly kind, gentle, and exceptionally skilled in his work. His entire team is professional, caring, and amazing at making patients feel at ease. I’m so grateful for the excellent care and compassion they showed me every step of the way throughout my surgery process.

Prem N. Ramkumar, MD, MBA

I first came to see Dr. Ramkumar because I was doing heavy miles and experiencing some knee pain and hip fatigue. He quickly diagnosed that I needed a hip arthroscopy surgery that would alleviate the pain and the fatigue. He did an amazing job in surgery and I began PT the very next day. I attacked the rehab hard with his guidelines and after 3 months I’m back to running around 30 miles a week preparing for a marathon! Dr Ramkumar is so cool and has been amazing throughout the whole process. I put a lot of trust in him and he gave me a lot of confidence as well that I would be back and better. Thank you Dr Ramkumar!! Much love.

Prem N. Ramkumar, MD, MBA

I highly recommend Dr. Ramkumar as my husband had an excellent experience. The level of professionalism, knowledge, and personal attention was outstanding. Dr. Ramkumar took the time to listen carefully explain everything clearly and made us feel comfortable and confident throughout the process. The staff was also kind, efficient, and caring. It is rare to find a doctor who combines such expertise with genuine compassion. We are very grateful for the excellent care received. We would highly recommend this practice to anyone needing expert orthopedic knee care.

Dr. Eric Millstein was my last minute second option, I'm filled with graduate for that chance to end up having my left rotator cuff surgery done by him. I can’t say enough good things about the entire experience. From my very first consultation, he was thorough, patient, and incredibly knowledgeable, he took the time to clearly explain my diagnosis, walk me through all my treatment options, and set realistic expectations for recovery. The surgery itself went smoothly, and I felt confident knowing I was in such capable hands. What really stood out, though, was the level of care and attention I received throughout the entire process, from pre-op to post-op follow-ups from the entire crew. Today, 10 weeks after the surgery, and only 5 weeks of physical therapy, I'm extremely happy and satisfied with my recovery progress, now I can see it thorough, full recovery is just around the corner. If you’re looking for a skilled, compassionate, and dedicated orthopedic surgeon, I highly recommend Dr. Millstein!!

Dr. Ramkumar has been one of the best experiences I could have asked for. I had a complex lateral knee injury that many doctors before misdiagnosed. Dr. Ramkumar was extremely honest, focused, and not rushed to surgery, in fact he was able in a few months get me back to normal without surgery, when many doctors prior said that surgery was necessary. He was very honest, no sugarcoating the truth, which to me is preferred when you have to make tough decisions. He was extremely knowledgeable and was able to explain the injury in a way that I couldn’t understand and feel confident in my decision making. This quality is very important when dealing with complex injuries where most average people do not understand the healing process and what you can and can’t do. I couldn’t be more grateful for him and the team putting such care into doing everything they could to heal my knee before rushing into surgery. I was concerned because this injury was quite unique I was worried I would t be able to find the right guy, but luckily I was able to get time with Dr. Ramkumar.

Prem N. Ramkumar, MD, MBA

Dr Millstein could not have been more helpful and precise discussing my options after an acl and meniscus tearing ski accident two weeks prior. He instantly gained my trust explaining the details of my injury from mri imaging and involved me in the choices I had to make on surgery v rehab . I cannot recommend him highly enough after my initial consultation. I chose the surgery route , and his team slotted me in quickly to get me back to work, which is my number one priority .10/10 .

Eric S. Millstein, MD

Dr. Ramkumar and his staff are truly the best! Going into my first appointment, I already knew I had a torn meniscus. However, after a simple X‑ray, Dr. Ramkumar immediately noticed that my ACL and knee alignment didn’t look right. It turned out that my previous ACL graft from eight years ago was not properly working anymore. Hearing that I needed an ACL reconstruction along with a meniscus repair was overwhelming, but the way Dr. Ramkumar explained everything—what happened, how he would fix it, and why gave me complete confidence that I was in the best hands. I was genuinely excited for surgery because I trusted him completely and knew he would be able to fix my knee so I could begin my journey back to lifting weights and swimming again. After surgery, I felt stronger than I ever have after a procedure. I was walking without crutches around two weeks post‑op. Dr. Ramkumar provides a clear, easy‑to‑follow post‑op plan so patients know exactly what to expect and how to track their progress. I’ve also spoken with other patients in the waiting room, and it’s clear he has helped so many people become pain‑free—from knee replacements to ACL repairs like mine, including both medial and lateral meniscus repairs. Now, three months post‑surgery, I can confidently say I am beyond grateful for my decision to walk into Dr. Ramkumar’s office for help with my knee pain. Dr. Ramkumar and his entire staff are incredibly kind, patient, and always willing to answer any questions. They make every office visit enjoyable because they’re such a warm and welcoming team. Ms. Stephanie was amazing to work with. She helped me plan my surgery date and made sure I had everything I needed leading up to the procedure. Ishan was also extremely helpful he answered all my questions and helped set up the post‑surgery app so they can track how their patients are doing. Overall, such a supportive and organized team! I would HIGHLY recommend Dr. Ramkumar and his staff to anyone needing hip, knee, or ACL surgery. He is truly the best, and I can’t wait for my next appointment! GOATED staff !! Thank you all so much!!

I felt I was in good hands, the minute I met Dr. Ortega. I trusted Dr. Ortega to perform Neck Cervical Radiculopathy ACDF. He is an amazing, wonderful and dedicated surgeon. His self assurance and self confidence, assured me I was in the place. Thank you so much to Dr. Ortega and his team! Thank you Ms. Elena! Thank you for your hard work and dedication!

Dr. Bae is knowledgeable, professional, and thorough. After seeing many doctors and having many tests, I finally feel like I have hope and trust in a doctor, Dr Bae.

On behalf of my Dad /Hector Valdez- Dr Ramkumar did an awesome job. He did his left knee robotic replacement surgery. It was a success and the recovery, care, follow up has been with so much care. We are now scheduling the 2nd knee surgery this summer and confident of the same outcome due to his excellent expertise and his caring team. Highly recommended.

Prem N. Ramkumar, MD, MBA

Experienced dos and team! They know what they’re talking about and explain it clearly. Came away with a confident plan!

After extensive research and consultations with multiple spine surgeons, I chose Dr. Brandon Ortega and that decision proved to be absolutely the right one. From the outset, Dr. Ortega demonstrated a level of expertise, precision, and clinical judgment that immediately set him apart. He took the time to thoroughly explain my diagnosis, reviewed imaging in detail, and clearly outlined the reasoning behind each treatment option. His approach was thoughtful, methodical, and grounded in both experience and evidence. Having been under Dr. Ortega’s care for several months prior to surgery, I always felt confident that my case was being managed with careful attention and long-term planning. When surgery became necessary, his professionalism and technical skill were evident throughout the entire process. The results thus far have been outstanding. For the first time in a very long time, I am not experiencing the back pain, leg pain, shooting pain, or numbness that had significantly affected my daily life. The improvement has been both meaningful and noticeable. Equally impressive was Dr. Ortega’s team. His staff and surgical coordinator were responsive, organized, and consistently supportive before and after surgery, a reflection of a well-run, patient-focused practice. Choosing a spine surgeon is a major decision. Based on both the process and the results, I can say with confidence that Dr. Ortega is an exceptional surgeon whose skill, judgment, and care truly stand out. I would recommend him without hesitation to anyone facing complex spinal issues. — Michael H., Long Beach, CA

Dr. Ramkumar has been the best doctor I have ever had the opportunity to see. Let me rewind a bit. I had a serious soccer accident when I was 16 that resulted in hip surgery at 17. At the time, I thought I was good to go. Unfortunately, my body had other plans. I only had about two pain-free years before the hip pain returned, and over the next 8–9 years it slowly got worse. What started as hip pain turned into back pain, knee pain, sciatica—you name it. I tried everything: physical therapy after physical therapy, aqua therapy, doctor after doctor. Every test came back “normal,” and no one could tell me what was wrong. It felt like either no one was looking hard enough, or no one truly understood what I was dealing with. That all changed when I met Dr. Ramkumar. At my very first appointment, he took new X-rays, looked at them once, and immediately knew what was wrong. For the first time, I finally had answers. Even more importantly, he took the time—despite his busy schedule—to sit with me and explain everything in a way I could truly understand. He is incredibly personable and never talks down to you like some doctors do. You can genuinely tell that he cares about helping you get your life back from chronic pain. I was understandably nervous about going through surgery again, but between Dr. Ramkumar and his amazing staff, I felt confident moving forward. And let me tell you—it was life-changing. I finally feel free from the pain that haunted me for so many years. I only wish I had found his office sooner. Every single staff member, from the PAs to the front office team, is kind, welcoming, and treats you like family. They make you feel heard, comfortable, and supported—qualities that are sadly rare in medical settings, in my experience. I am beyond grateful for the care Dr. Ramkumar and his team have provided, and I wholeheartedly recommend him to anyone who is sick and tired of living in pain.

My experience at the clinic, and this was the first time I was there and the first time I met Dr Eric Millstein was uplifting, inspiring, spiced by a fantastic sense of humor, full openness and a feeling of complete trust, sharing the same perspectives and met an open minded doctor, extremely knowledgeable, and I actually felt like a butterfly when leaving the clinic. We discussed the problem, agreed on the future decision I would have to make about a surgery, but no pressure and no gambling, he decided to send me to an MRI, just to make sure it wasn’t worsened since the previous MRI Thank you, Dr Eric Millstein and the whole staff
