Dr. John Hayes concentrates his cardiology
practice on diagnosing and treating patients
with heart rhythm disturbances. “It’s a
pleasure to provide people with quality
care and improve their health,” he said.
He came to Marshfield Clinic in 1991,
attracted by its high-quality practice, the
community’s family-oriented environment
and positive feedback from patients who
had been referred to Mayo Clinic during
his residency there.
Dr. Hayes earned his medical degree at
Rush University Medical Center-Rush Medical
College, Chicago. He completed his residency
in internal medicine at the Mayo School of
Graduate Medical Education, Rochester,
Minnesota; and a fellowship in cardiology and electrophysiology at the University
of Washington, Seattle.
Dr. Hayes is board-certified in internal medicine, cardiovascular disease and clinical cardiac electrophysiology, and is a
Fellow of the American College of Cardiology
and the Heart Rhythm Society.
He and his wife have three children.
He enjoys fitness activities such as
running, bicycling and basketball.
