This was an excellent first visit with Dr. T. She was well informed, a great listener, and I felt confident that she was willing to work to help me.

if upmc had more doctors like Dr twitchell, upmc would have a FAR better reputation

Dr. Twichell saved my career. She is incredibly empathetic and practices effective medicine and recommends effective therapies.

February 14, 2018

Dr. Twichell was very attentive to my and my wife's answers and questions. She had all the information she needed, made a plan of action, and acted on starting my treatment that moment. She is very personable and gave us her full attention while we described my injuries and the problems that they have created. in all, I liked her very much. I would recommend her to anyone that needs pain management post their concussion.

Dr Maria Twitchell is one of the best caring knowledgeable doctors I have ever met in my life always treat me with respect and show me she concern and care about my health

Dr Twitchell is so impressive. I have been under her care and Dr. Camiolo-Reddy for years. Now I am on a 6 month check up time table. Dr Twitchell has an excellent way of summarizing our last visit including medical and personal details. Wow, Kudos to her. She is personable, reliable, trustworthy and a total medical professional. I can never thank her enough for how positive a physician she is. When we are together she makes me feel as if we a best friends. My father, who is 79, is at all of our appointments. He always comments on how she is the only doctor he has ever run across that explains my condition in way he understands, That really is saying something because I'm always with him for his appointments and the minute we are out the door he will turn to me and say, "OK so what did he just say?". I love my UPMC I just wish you could expand a satellite office to Mahoning County in Youngstown, OH, Don't get me wrong I would never change my Dr. Twitchell, however the faith and trust I have in her and UPMC I would love to have your general services offered here.
