    The Bottom Line: 5 stars: Great option for orthopedic care. Easy to get to, plenty of parking, and…read morefriendly and helpful staff. Highly remmended! Location 5 stars: On Erringer Road in Simi Valley, California, North of Cochran Street, in a larger shopping plaza. Plenty of free parking right in front of the clinic or at the most a short walking distance. Venue 4.5 stars: Large well kept facility with X-ray on site and their own rehab center across the parking lot. You can check online before going or while in the office (just scan the QR code displayed there) and this makes everything faster. Large comfortable wait area. Wait time was less than 10 minutes past my appointment time. Service 5 stars: Friendly and attentive front desk staff, medical staff and physicians.

    My first visit to this location was on a Thursday. They were so busy in the afternoon that there…read morewas virtually a line out the door waiting to check in. They had three associates working to get patients checked in or out as the case might be. They were moving through the queue as fast as they could. When my turn came to check in the representative was very friendly and thorough, despite the chaos of so many people in the waiting area. I asked if it is always that busy there. She said that Thursdays are often their busiest days. Dear Hubby explained (he's been a patient there, too) that their doctors rotate to several offices - likely Thousand Oaks and Camarillo, in addition to Simi. Despite the busy load of patients in the waiting room I was called in fairly quickly. Dr. "Siva" came to talk with me and go over MRI results shortly thereafter. There were some surprises in what the MRI revealed which I wasn't expecting. I'll be starting physical therapy soon and we'll see how it all goes. I liked the straight-forward communication style of Dr. Siva. He offered information, compassion, and a plan to move forward.

    great doctors and i will miss them. i've had knee, foot and two shoulder surgeries that were…read moreperformed to perfections. support staff and management did not performed to the same level. no call backs, rude, argumentative and disrespectful. i suggest the scoi company get on top of training staff and changing to a more personal management style for their customers. when doctors are not informed in real time, if at all, the patient can end up in an emergency room after a procedure, as i have. sorry scoi, you've lost another one. the doctors and patients deserve much, much better.

    I DO NOT recommend this place. Very poorly managed…read more - X-ray techs did not protect the rest of the body. I had to request the protective apron. - PT office overbooks; PT is unable to watch, adjust, and make sure you're learning enough about how to properly do the movements because they're focused on more than one client at a time. - Lots of socialization between the PTs; it's great to have fun at work but not when there's a patient in front of you - Doc wouldn't give any diagnosis without scans. $300 later + exposure to radiation, with no further in understanding or explanation of the issue. My acupuncturist was able to tell me what's going on after a short evaluation. - Doc made me return and pay a second copay for a full evaluation because he refused to assess more than two body parts per visit, even though everything is connected and related - Front desk (quite grumpy) refused to schedule my third appointment stating there was an insurance issue; we were told it's a training matter when we escalated Too many issues! If you'd like to know where I went for PT and got much better results, you are welcome to DM me OR just check out my reviews for the other PT office (there's only one other).

    I had total hip replacement of my left hip just over 8 weeks ago. I scheduled this surgury with Dr…read moreRana at the Tarzana Center for Orthopedic Specialists, so I was in and out in about 7 hours total. I cant recommend Dr Rana and the support staff highly enough. From the moment I walked in I was greeted and taken care of by caring professionals. The surgery went smoothly and after about 2 hours in recovery I was on my way home. Dr. Rana and his team were very efficient and thorough with timely pre-op information, as well as explainations of what to expect with the surgery and the recovery. He is both a highly skilled surgeon, and a caring human being. I have little to no pain after 8 weeks and my mobility is very good; walking, climbing stairs, traversing irregular terrain, beach sand, and working around my property. I am back to playing pickleball a few times a week without any soreness or swelling, although I will admit I am playing a bit more conservatively for a while to be sure I do no damage to his fine work! I consider this proceedure to be a total success all owing to Dr Rana's skill and professionalism.

    In 2025 I underwent total knee replacement surgery with Dr. Rana and had an outstanding experience…read more I researched many surgeons and chose him because he was the most highly recommended and he truly lived up to it. His skill, experience, and attention to detail are exceptional, and he has a cheerful, reassuring bedside manner. What impressed me most was how attentive he was after surgery, personally following up with me multiple times and genuinely caring about my recovery. The office staff and surgical team were excellent, and my surgery at Tarzana Hospital was a great experience. I am extremely grateful for the results of both surgeries and would highly recommend Dr. Rana to anyone considering knee replacement.
