Ryan E. Radwanski

About

Dr. Ryan Radwanski is a Family Medicine resident physician at Hunterdon Health and a United States Marine Corps combat veteran who served as a Sergeant in Afghanistan. He earned his Doctor of Medicine from Weill Cornell Medical College, graduating with Honors in Service, after completing a Bachelor of Science magna cum laude at Cornell University. Before family medicine, he spent years in neuroscience and neurosurgical research, authoring more than thirty peer-reviewed publications on traumatic brain injury, stroke, and medical education. He brings that whole-person, research-grounded perspective to comprehensive primary care, with special interests in neurologic injury recovery, chronic pain, and preventive medicine for the whole family.
