After graduating from Cornell University Medical College, Ford Ballantyne came to the University of Wisconsin for an internship, later receiving the award for Outstanding Medical Intern. He completed his residency and fellowship at the University of Wisconsin. During his fellowship, he received Wisconsin and National Institutes of Health grants for research in single cell electrophysiology, and spent time in Pediatric Cardiology.
Completing his fellowship in 1975, Ballantyne went into private practice until 1981 when he joined the UW Division of Cardiology. Two years later Ballantyne became the director of the Cardiology Fellowship Program and co-director of the second year cardiovascular pathophysiology course. In 1984 he was presented with the Medical Residents' Best Teacher Award, and in 1995 he received the Basic Science Teaching Award. Ballantyne began the Adult Congenital Clinic in 1990, which he currently co-directs.
An Associate Professor of Medicine, Ballantyne has dedicated much of his career to teaching Cardiovascular Medicine to interested students, residents and fellows. His other interests include congenital heart disease in adults, single cell electrophysiology, echocardiography and the integration of cardiology and internal medicine.
