Leadership Development Program

EMA is proud to offer a Leadership Development Program to our board-certified physicians. Each year, EMA selects several qualified individuals from within our organization who have shown interest and ability in becoming a part of our physician leadership team. Our program allows for participants to be guided through the fundamental concepts in ED management including metrics and analytics, collaborative change, and becoming a thought leader. Participants will also learn to help drive organizational change through site-based projects, participation in organization-wide initiatives, and representing as an active administrative ED leader. Additionally, participants will gain a more broad-based education by attending the ACEP Director’s Academy, a program comprised of relevant topics, break out sessions and focus on case studies of every day ED challenges and operations. Our Leadership Development Program can help focus and foster promising leaders from within our diverse organization to help lead EMA into the future.

These goals are the focus of an EMA provider.

Since 1991, EMA has experienced tremendous growth in our geographic footprint. We are proud that we have continued to recruit, develop and retain a talented group of emergency physicians who help us staff and run high-quality, patient-centered emergency departments.

We now have over 20 active Directors and Assistant Directors managing and leading the clinical and administrative directives of each site. Some of this talent was cultivated from the front lines while others have naturally progressed into leadership roles within our organization.

Our Leadership Development Program aims to provide multiple layers of opportunities for physicians to develop the tools and skills necessary to become part of our leadership team.
