He didn't explain how degraded my labrum was or about the mild spurring on my Glenohumeral joint. I would guess it wasn't really bad but it would have been nice to know.

I had been told multiple times by my Orthopaedic Physician in Idaho Falls that doing a revision might make matters worse. This was very discouraging to me. At my follow up from my ultrasound, he told the PA to give me the name of the doctor that he/they had just referred another patient to, that was in Salt Lake City. After meeting with Dr. Tashjian, I felt more hopeful that my shoulder problem could be fixed.

The staff, Gabe, and Dr. Tashjian were all excellent. The MRI scheduling gentleman was excellent too, and very accommodating. Dr. Tashjian spent a lot of time explaining and discussing my results, potential surgery, and prognosis. I had previously scheduled surgery with another surgeon here but changed when I understood how thorough and thoughtful Dr. Tashjian is. My appointment went better than even expected. I am very impressed and look forward to him replacing my shoulder.

Dr. Tashjian comes across and quite arrogant and made me feel as if I were wasting his precious time. I only scheduled the appt to see him at the request of my regular doctor and my appointment was delayed due to Covid. My husband was with me and as soon as we walked out my husband turned to me and said, "I don't like that guy, let's get a second opinion on your shoulder from outside the UofU."

I saw Dr Tashijan after a shoulder injury from a skiing accident. The time he took with the history and physical exam along with the explanation of how the course of treatment and follow up was an extraordinary experience. All my questions and concerns were addressed and elaborated upon. I am so grateful for the care and thoroughness he took to answer all my questions and expand upon how he and his team would reevaluate my injury while under his care. I left with great confidence in Dr Tashijan and the University of Utah care team.

I have had years of experience with my care provider, Dr. Tashjian and my outcomes have always exceeded my expectations. He is an incredibly skilled, knowledgeable and compassionate Orthopaedic Surgeon. He always takes as much time as necessary to explain my issue(s) to me, listen to, and answer my questions and concerns, discuss my options for treatment, including risks and benefits and work with me to develop the best treatment plan possible. I have recommended him many times. In my opinion, he is a model that others should seek to emulate.
