Through collaboration, Mercy Health Partners (MHP) of Southwest Ohio, Cincinnati, and Catholic Social Services (CSS) of the Diocese of Scranton, PA, built a housing complex for low-income seniors and developed a variety of supportive services for residents. St. Catherine's Manor aims to meet elder adults' social and medical needs through offerings such as on-site health assessments, meal services, and transportation help. In order for the collaboration to be a success, MHP, CSS, and their partners had to trust one another. They also had to be clear and deliberate about their roles and responsibilities, thereby establishing expectations well in advance of the project. Their partnership was enhanced because they shared a common culture.
