Toyin Ajayi, MD, MPhil, is Chief Medical Officer at Commonwealth Care Alliance (CCA), a Massachusetts nonprofit health plan and integrated care delivery system created to provide high quality care to people with complex health needs. CCA manages over 800 million dollars annually to care for more than 17,500 individuals who, by virtue of being over 65 and low income or disabled and low income, are dually eligible for Medicare and Medicaid benefits.


As Chief Medical Officer, Dr. Ajayi directs clinical programs and oversees clinical care delivery, care management, and clinical operations. CCA’s portfolio of innovative programs includes integrated home-based primary care and enhancement services; community respite facilities providing acute psychiatric crisis services; a nationally-recognized end-of-life program; a comprehensive care transitions and post-acute care program; and a groundbreaking community medicine pilot program in partnership with the Massachusetts Department of Public Health and EasCare Ambulance Company that deploys specially trained paramedics to members’ homes to evaluate and provide appropriate treatment for acute complaints as an alternative to emergency room or hospital visits.


Dr. Ajayi is a board-certified family physician and maintains an active clinical practice, serving as primary care physician to forty women over 65 years of age who are homeless or marginally housed. She also serves as a Boston Medical Center (BMC) hospitalist, caring for acutely sick patients admitted to CCA’s shared inpatient service unit at BMC.


Dr. Ajayi received her undergraduate degree from Stanford University; an MPhil from the University of Cambridge; and her medical degree, with Distinction in Clinical Practice, from King’s College London School of Medicine.
