Jonathan Pinto, PAC

-He attended UCONN at Storrs, graduating in 1998 with a Bachelor of Science in Physical Therapy.

-Returned to Quinnipiac University Graduate PA program, graduating in 2004 with a Masters of Health Science in Physician Assistant studies.


-Mr. Pinto started off as a physical therapist in Waterbury, CT as an inpatient/outpatient therapist, with a focus on inpatient orthopaedics and trauma.  During his time spent there, he developed a keen interest in the surgical side of orthopaedics and was advised by some great physician assistants to return to school for an advanced degree.

-Mr. Pinto’s background of physical therapy naturally led him to the field of orthopaedics and started working at St. Vincent’s Medical Center in Bridgeport, CT in September of 2004 and has not looked back since.  Mr. Pinto’s knowledge and skills continued to grow and thrive under the guidance of a great group of orthopaedic surgeons and physician assistants, advancing his skills in the operating suite, the emergency department, as well as at the bedside.

-As a seasoned physician assistant in orthopaedics, he embraces the controlled chaos of the hospital setting and remains most interested in acute trauma, reconstructive surgery, and advances in joint replacement.  Working alongside a group of skilled orthopaedic surgeons, he is now a member of the OSM team as one of the physician assistants for the OSM STAT clinic and has further broadened his skills in this diverse setting.

-During his time as a PA, he has participated in the education of future PA’s by being a preceptor for clinical rotations as well as an adjunct faculty for both the Yale University PA program and University of Bridgeport PA Institute.
