John DeAngelis

John DeAngelis is the newest addition to the Ultrasound Faculty.

He trained in Rochester but only recently returned after completing a Fellowship In Buffalo, NY, and a stint in Boston, MA. He is part of both the ultrasound and research divisions which allows his role to include clinical ultrasound research. He is currently involved in several ultrasound projects with his focus in pre-hospital ultrasound use. He also remains active in resident education.

He is a dedicated nocturnist, but when you see him during daylight hours he is always willing to grab a beer or lunch at one of the local spots. A dedicated hobbyist, he has an ever growing menagerie of outside interests.

I fell in love with ultrasound because it makes me a better doctor, and has gotten me out of some tough spots.”
