Dr Robert Tashjian was highly recommended to me as a reverse shoulder surgery expert. Following past recurring rotator cuff tears and unsuccessful repairs, the reverse procedure was my only option. Dr Tashjian has been patient and kind about my reluctance to do yet another surgery within the last 15 months, and he has treated my case with sincerity and clarity. I feel that he really cares about my desire to greatly improve the use of my right arm and shoulder, which have been compromised with pain and lack of movement for nearly two years. I am hopeful that together, along with my PT rehab team, we can reach my goals and reclaim my active life of fitness, gardening, everyday household chores, hobbies, and travel.

May 30, 2025
ORTHOPAEDICS CENTER

I feel Dr. Tashjian is an amazing, competent Doctor. However, waiting 50 minutes past my appointment time made me feel he was rushed, hurried to make up time, catch up. I understand and appreciate that he obviously needed more time with the patients before me. I just felt a bit rushed. I needed a bit more attention, alternatives, understanding and planning. I did my best to communicate my concerns, my special circumstances (I'm a full time care taker of my husband) and ask the appropriate questions. I felt a bit rushed into making life changing surgery in a very short time.

As a former Administrator of a Rehab Hospital and several Assisted Livings over my career I found this Surgeon unprofessional, rude with no empathy.His opinion was based totally on X-Rays he touched the area of concern one time. I don't doubt he is a good surgeon but socially he needs to learn what a good bedside manner means. Getting well includes kindness, empathy and tact.
