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.

Ive seen multiple doctors for my concussion issues. She is by far the most outstanding. I no longer have consistent every day headaches which makes a huge difference in my life. She also is knowledgeable in holistic care, with my background I like to use essential oils, teas, etc and she is in the know and able to help me in that department as well!!!

Dr. Twitchell is a caring and compassionate physician. I also must compliment her nurse, Marion and the receptionist, Toni on their caring and professional manner.

Dr. Twichell is the best. She is caring, concerned about me and really knows her information. I highly recommend her to anyone and talk about what a good doctor she is when asked who it is I see for my concussion.
