As a veterinary cardiologist, Dr. John Rush has a special interest in drug and dietary therapies for the treatment of heart disease in small animals. He also performs many catheter-based procedures (interventional radiology), including the placement of pacemakers, coils and stents. In addition to his clinical duties, Dr. Rush teaches cardiology to second and third-year students and mentors fourth-year students in the Foster Hospital for Small Animals. He is also the associate chair for the Department of Clinical Sciences, the Cummings School's largest department.
Growing up near Cleveland, Dr. Rush had a natural affinity for science and spent a great deal of time at the Lake Erie Nature and Science Center.
I collected insects, and if I had not become a veterinarian I might have been an entomologist, he says. He attended The Ohio State University for his undergraduate and veterinary degrees, then furthered his training in New York and Wisconsin. Drawn to the Cummings School of Veterinary Medicine by a love of teaching, he joined the faculty here more than 20 years ago.
He likes the mix of teaching, clinical research, and caring for dogs and cats with heart disease, as well as the motivated and gifted students of the Cummings School. He has served as the primary mentor for two dozen veterinary residents in emergency and critical care and cardiology and has published on topics ranging from heart failure and respiratory distress to quality-of-life issues for pets.
Off-campus, Dr. Rush is very involved with both the American College of Veterinary Internal Medicine and the American College of Emergency and Critical Care, and he is a diplomate of both societies. He has three dogs and counts home improvement as his favorite pastime.
