President's Profile

Dr. John WhelanDr John Whelan, MD FRCPC
Diagnostic Radiologist 
Saint John 

Dr. John Whelan, who practices diagnostic radiology in Saint John, loves the fast-paced, constantly changing nature of his specialty.

“It was a very fast moving specialty that had a lot to offer patient care,” he says of his initial attraction to the field.

Dr. Whelan was born into a health care focused family - his father and his older sister were pharmacists, and his mother was a lab technician. In keeping with the “family business,” he received his medical degree from Memorial University of Newfoundland in 1980. Following one year of general practice in Moncton and three years of emergency medicine at the Moncton City Hospital, he moved to Halifax to complete a four-year residency in Diagnostic Radiology. Since 1989, he has practiced at the Saint John Regional Hospital.

“Radiology was an emerging field when I entered it, and now we’ve evolved even further,” said Dr. Whelan.

MRIs and CT scans feature heavily in many patients’ interactions with the health care system. Dr. Whelan also performs interventional radiology, which includes running stents and other instruments through arteries rather than performing surgery. Stroke patients are among the beneficiaries of these life-changing procedures.

Dr. Whelan holds an appointment as Associate Professor in Diagnostic Radiology at Dalhousie University, and serves as Education and Residency Training Director at his hospital. He has been active with the New Brunswick Medical Society for over 20 years. Over time, he’s served as Section Representative for his specialty, as Treasurer on the Finance Committee, and as a member of the Executive Committee.

Outside of work, Dr. Whelan enjoys golfing and downhill skiing. He’s also an active squash player. He and his wife Dr. Margaret MacCallum live in Rothesay. The couple has three children: Alex (fourth-year medical student), Jennifer (Master’s student in architecture), and Jonathan (fourth-year science student).
