Welcome to Hamilton Arms Center! Hamilton Arms Center is a proud part of the Lancaster Community. Located on the west side, near Franklin and Marshall College and the downtown historic area, our patients and residents represent a cross section of true Lancaster county. Our newly renovated facility has a designated ShortStay Unit for patients that are not quite capable to return home alone after a hospital stay. Our LongTerm residents call the second floor home and enjoy various community activities. The summer weather brings our residents outside on the patio to enjoy visitors as well as our 4-legged furry therapy friends.
