    Great Dr.! He took time with me and explained the situation. He recommended the care I needed. My follow up with him was good. He was kind and told me to call in the future if I have any further issues

    ORTHOPAEDICS CENTER

    It was a very productive visit and Dr. Tashjian offered solutions to my concerns.

    He is first rate.

    I wish I could have found him a year ago. I was told I had arthritis in my elbow and I had to just live with it(by a different Dr) , Dr Tashjian confirmed what I knew that it wasn't arthritis. I had a torn bicep tendon. He took the time to explain everything to me about the surgery. He is very thorough and definitely knows what he is doing, I am very very thankful and can't wait to be out of pain..

    ORTHOPAEDICS CENTER

    When I first started seeing Dr. Tashjian for my shoulders several years ago, I felt like he spent much more time with me. This in-person visit seemed rushed. I was hoping to see the MRI with him to understand more of what he described was going on. It wouldn't change the outcome but I would feel more well informed. I was also disappointed that I have to wait three and a half months before I can have the corrective surgery. I wasn't given any advice or support about how to manage the pain and limited motion between now and then. (although I should have asked)

    Ive been seeing him for a couple of years now and hes very direct about what needs to be done and why. He gives you the time needed even if hes a busy doctor, and he listens

    ORTHOPAEDICS CENTER

    After talking to Dr. T I have full confidence my shoulder will be better than ever, and I can get back to a normal life. After my consultation, he gave me hope that I can get back to normal, and I am looking forward to that!

    ORTHOPAEDICS CENTER

    Dr Tashjian was well prepared for visit had reviewed the X-ray and MRI was ready to discuss condition and options for care and corrective action
