APD transitioned from a cottage hospital to a modern hospital with a new building in 1964.

Philanthropic support made a major renovation possible in 2012 to the hospital’s medical-surgical inpatient wing. It included 15 private and two semi-private patient rooms, each with a spacious family area, private bathrooms, showers, a palliative care family suite, a four-patient observation unit, and an inpatient rehabilitation gym.

In 2021, the hospital’s east wing was renovated into a 10-bed short stay surgical unit. It is designed to meet the unique needs of patients requiring surgical procedures with hospital stays of less than 24 hours.
