Cambridge, Mass. (February 27, 2023) – Vinfen, a leading provider of community-based services for people with mental health conditions, intellectual and developmental disabilities, brain injuries, and behavioral health challenges announced today that Peggy Johnson, MD, will join the organization as Chief Medical Officer (CMO) effective April 3rd. In this role, Dr Johnson will lead the organization’s clinical strategy development and execution, ensuring that Vinfen’s community-based mental health and disability programs are positioned to deliver high-quality, clinically-focused, and person-centered services. Johnson succeeds Dr. Don Condie who will remain with the organization as a regional medical director supporting the growing needs of our Northeast Adult Community Clinical Services (ACCS) programs.

“For most of my career, I have been focused on ensuring access to essential mental health services for vulnerable populations. The work Vinfen and its talented leadership team, skilled providers, and committed direct care workers do to support people with mental health conditions, disabilities, and life challenges is critical to those we serve and the region at large,” said Johnson. “I am particularly excited to continue to build partnerships with public and private entities, foster innovation, and assure that our workforce has the resources it needs to succeed.” 

Johnson has an extensive background in caring for individuals with chronic mental health conditions, in both clinical and operational settings. For the past nine years, Johnson has served as Vice President and Chief of Psychiatry for Commonwealth Care Alliance (CCA), where she was instrumental in driving strategic initiatives to better support individuals with mental health conditions. Prior to her work at Commonwealth Care Alliance, the majority of her career was as Vice President of Psychiatric Services at Boston Medical Center, the largest safety net institution in New England. Johnson began her career as a public sector psychiatrist with a focus on those with chronic and persistent mental health conditions.

“Peggy has dedicated her career to supporting individuals with mental health conditions and intellectual and developmental disabilities. Her background and expertise will blend seamlessly with Vinfen’s mission of supporting the people we serve in living full and meaningful lives in their communities,” said Jean Yang, President and CEO of Vinfen. “We are grateful to Don for over a decade of service to Vinfen as Chief Medical Officer, where his guidance enabled countless people to access the care and support that best served their needs. We look forward to continuing this unwavering commitment to transforming lives through Peggy’s leadership.”

Johnson trained in general adult psychiatry at Harvard Medical School’s Cambridge Hospital Psychiatry Residency Program. She holds a BS from University of Houston and an MD from Baylor College of Medicine. She has received numerous awards and honors – including the Marie Feltin Award, the NAMI Exemplary Psychiatrist Award, and the Massachusetts Psychiatrist Society’s Outstanding Psychiatrist Award – and has served as a lecturer at a number of institutions.
