Dr. Tashjan has replaced both of my shoulders, plus helped me with rotator cuff tendinitis from caring for my dying husband. He has vastly improved the quality of my life. I am able to live a normal life and rarely experience any amount of pain. I would recommend him to anyone needing care of their shoulders. I am so grateful that when I explored and found him years ago that he was there. He is a very caring, considerate and expert surgeon.

I overheard the doctor talking to the resident? In the hallway before he came in. He told the resident that 51 year old women don't have instability in their shoulders (which I do have and have had 3 previous surgeries to attempt to fix that problem). I wasn't happy that he had already made his opinion before even seeing or examining me or talking with me. I felt he was arrogant and condescending but unfortunately my doctor referred me to him because he is the best and I need this fixed.

I felt the appointment was rushed and that Dr Tasjian was slammed with patients and I didn't get all of my questions answered as easily as I had hoped. I am sure that it is not his fault that because of his patient load. it unfortunately is the way of medicine today due to the pandemic.

Dr. Tashjian is the best surgeon for shoulders as I did my research before coming in and selecting him. I was not disappointed in the entire process with him and his staff. All members from anesthesiologist to nurses, to schedulers, to hospital care were Top Shelf.

Truth? Dr. Tashijan KNOWS how valuable it is for me to be able to use my arms fully. Because of my deafness, I depend on American Sign Language to communicate and it is my job, too. Dr. Tashijan has never failed to immediately focus on the concerns I have. He responded very well and I love him.

Dr.Robert Tashjian is exceptional. I saw him 10 years ago for a small problem with my opposite shoulder, which is doing great. He has also replaced both of my husbands shoulders, and one of my mother-in-laws, and the surgeries all were successful with no complaints 10-15 years later.He LISTENS, which is more than I can say about a lot of high level surgeons, and GENUINELY CARES.

Doctor seemed very rushed, possibly because my appointment had to be rescheduled for meetings so he was probably overbooked. He didn't even introduce himself, just walked in the room and started talking about my MRI. Did a quick assessment, maybe <5 min, and then told me the treatment would be there same thing I've already tried for the past 10 months without any significant changes in my symptoms.
