I have been a patient of Dr. Mastrangelo's for years and love him. He is very very thorough and always has provided the correct treatment for me. The staff is wonderful. I highly recommend Dr. Mastrangelo. He is very easy to talk to. He is very willing to listen. After suffering many many years with severe ulcerative colitis, he has been able to manage my problem very successfully. Thankfully I have been in remission for a long, long time. I continue to get my screenings every year and do exactly what he tells me to. If you are looking for a new doc or a second opinion, Dr. Mastrangelo is the one to see.
