The University Of Pennsylvania Department Of Psychiatry through The Center of Excellence and Innovation in Public Psychiatry and the Penn Center for Mental Health offers a one-year post-residency fellowship in Community and Public Psychiatry. The fellowship was created as a cooperative program with community mental health agency partners and the Commonwealth of Pennsylvania and is designed as subspecialty training for psychiatrists who plan leadership careers in the public sector.

The core of the fellowship consists of supervised work at collaborating public sector agencies in Philadelphia. These field placements are complemented by an academic curriculum that teaches clinical, leadership and administrative/management skills that will provide fellows with the tools and expertise to become part of the next generation of leaders in public psychiatry.

A major part of this program is the ongoing support of a community of previous fellows in the mentoring and supervision of the new fellows.  The fellowship is designed to immerse fellows in clinical team leadership experiences and wide exposure to the range of services in the system in Philadelphia. Philadelphia is a particularly rich environment for community psychiatry opportunities with a unique funding structure for behavioral health services.

The active participation of the city Department of Behavioral Health Services provides opportunities for fellows to be involved in a variety of public policy experiences.  Each fellowship experience is individually designed to enhance the skills of the fellow and provides a range of clinical practice sites and academic opportunities. We strive to create a creative learning environment with didactic and experiential learning experiences. Fellows are expected to complete an independent research or organizational project as part of the fellowship.

Fellows receive a minimum annual salary of $95,000 plus full benefits. Additional funding is available for conference and educational activities. Additional funding is available for conference and educational activities. Fellows receive weekly individual supervision from program leadership.
