“I work with each patient to identify the method of medical treatment that will benefit them the most,” Dr. Hartung says. “Often times that includes ways that we can tap into the body’s own inherent ability to stay or get well.”
A graduate of the University of Iowa, Dr. Hartung completed his family medicine residency at Iowa Lutheran Hospital in Des Moines, Iowa. He is board certified in family medicine.
Dr. Hartung enjoys cooking, performing arts, gardening and traveling. He is married with three grown children.
