Even went back to fitness training (scaled and modified ofc). I was recommended to Dr. Guanche by my other orthopedic surgeon, Dr Trentacosta. She's incredible as well but her specialty is with knee injuries, not shoulder. After my shoulder injury, I tried extensive physical therapy. PT went on for 6 months, but unfortunately the pain was still there. Per my doctor, an injury like mine needed surgery, it won't heal otherwise. I didn't want the tears to get worse, so I looked into getting surgery. I was hesitant at first, but Dr. Guanche quickly calmed my nerves and discussed all my worries away. Fast forward 5 months after I had my first meeting with Dr Guanche, I'm now post op and able to do more. Slowly but surely, I'm getting more range of motion back day by day. So grateful for Dr. Guanche!

I injured my knee when I was 14 yrs old and now at 65 am still having issues, with other areas of my body (due to my "gait" ) which has caused different body areas to be affected. I don't know what I would have done if someone hadn't told me about SCOI. It's like a " One Stop Shop" for all your Ortho Issues.

After I slipped and fell on my back, I developed severe back pain, hip pain, pain going down the back of my leg toward my knee, and numbness in my toe. The pain became so intense that there were many nights when I simply couldn't sleep or get comfortable. I eventually had an epidural injection with Dr. Vahedifar, and after a few visits and his continued care, my pain became much more manageable. I'm incredibly grateful for the difference this has made in my everyday life. Dr. Vahedifar is not only extremely knowledgeable and skilled at what he does, but he is also compassionate, patient, and genuinely caring. He takes the time to listen, understand what you're going through, and make you feel that you're in good hands. When you're dealing with severe pain, having a doctor who truly cares and knows what he's doing makes a huge difference. I'm very thankful I found Dr. Vahedifar, and I would highly recommend him to anyone dealing with back or nerve pain. Thank you, Dr. Vahedifar, for helping me get my life and sleep back. You're truly amazing at what you do!

I was there for knee pain and all he did was read over my previous doctor's notes (now retired) and we agreed upon my continuation of the Euflexxa injections for my knee. I was shocked that he never even examined my knee durning my first office visit with him. This appointment was over six weeks ago and I am still waiting on an approval for my Euflexxa injection which usually takes 1 to 1 1/2 weeks for the approval. I have spoken with Cecily at the office for help on two occasions. The first occasion, she said the there is a delay with Optum and could take up to 4 weeks for approval. Please keep in mind that I am in knee pain. When I called again on August 10, 2026, Cecily said that she cannot tell me the status of my medication and would leave a message for the person who could help me. This person who Cecily promised would help me, never called me back. Wednesday of last week, I called my insurance provider in order to help me find out the status of my medicine and we spoke with Karen. Karen promised that we would have the medication by last Friday. Once again, Karen nor any other person called me back from Dr. Nadel's office. As of yesterday, I filed a complaint with my insurance provider and the lack of help with Dr. Nadel and the office staff. How can the office staff here ignore someone who's in pain and not work on getting the medication that I have been using to relieve the pain now for a couple of years. This is unconscionable.
