BALTIMORE (WJZ) — Johns Hopkins Hospital is making history Thursday after naming their first female president since the hospital was founded in 1889.

Dr. Redonda Miller, who first came to Hopkins as a medical student, will assume the role starting on July 1.

Miller will replace Ronald R. Peterson, who has held the title of president of the Johns Hopkins Hospital for 19 years.

“Redonda’s extraordinary combination of exceptional medical prowess, years of progressive administrative experience, and the well-earned respect of senior clinical and administrative leadership will serve us all well,” Peterson wrote. “Her deep understanding and appreciation of The Johns Hopkins Hospital’s culture and her working knowledge of the Maryland financial rate-setting system make her extremely well suited to lead at this time in our history.”

With more than 20 years of service at Johns Hopkins, Miller most recently served as the senior vice president of medical affairs for the Johns Hopkins Health System and vice president of medical affairs for The Johns Hopkins Hospital.

Miller co-chairs Johns Hopkins Medicine’s United Way Committee and the Maryland Hospital Association’s Council on Clinical and Quality Issues. She has served on dozens of administrative, medical education, system innovation and quality improvement councils and committees at Johns Hopkins and is a member of several professional boards.

Miller, 49, is married to physician Albert Polito, a pulmonologist who directs the Lung Center at Mercy Medical Center. They have two daughters: Francesca, 11, a fifth grade student; and Bianca, 7, a first grade student.
