This was my first time meeting Dr. Griglione. Since my other gastroenterologist moved to a different facility that isn’t in my network, I needed to find another provider who can do my colonoscopy in a few months. The appointment felt a bit rushed since they only allowed a half hour for a new patient appointment and I have extensive health issues. Some of the health issues I shared with her were inaccurate in her notes after my visit. I believe she is knowledgeable about colonoscopy procedures, so hopefully everything goes smoothly when it’s scheduled.

Colonoscopy Scheduling and then rescheduling was easy. Procedure facility was convenient and easy to navigate. Office staff, nurses, and assistants were friendly and knowledgeable. They answered all my questions and concerns. Doctor has a great bedside manner - calming. Doctor took time to explain the procedure and followed up after recovery. I would recommend Dr. Griglione.

Dr. Griglione only talked to me after the procedure when I was still groggy. She did explain the issues and did not take time to hear by medical background. She had her staff contact me to "answer my questions" when she had never talked to me or contacted me.

Dr. G is fantastic. She performed both an EGD and a colonoscopy on 5-21-19. She is incredibly detailed in her report. Her staff is excellent as well.
