All of the Staff that worked with me were very friendly and easy to talk to! I loved how caring the office was and how important I felt. I did not feel like just another patient walking in the door. The nurse I had in the beginning was great, Alyssa the PA was awesome, the dietician and social worker that came in just to check on my status and how I have been feeling, and this was my first visit with Dr. Regueiro and he is by far the best doctor I have had since I became a patient at UPMC. Thank you guys, as always, for the great care!
