The Cigna Group announced that Dr. Amy Flaster has been named Chief Medical Officer of The Cigna Group, effective November 1, 2025. Dr. Flaster, who joined the company last year as Chief Medical Officer of Cigna Healthcare, will now serve in an expanded enterprise role across both Cigna Healthcare and Evernorth. In this capacity, she will spearhead efforts to advance clinical excellence, introduce innovative care models, strengthen and grow clinical teams, and leverage technology to enhance whole-person health.
Since joining Cigna, Dr. Flaster has been a driving force behind several clinical programs that improve health outcomes and affordability for customers and clients. Her leadership has helped shape the organization's approach to integrated care, behavioral health, and digital health innovation. Dr. Flaster will report to Brian Evanko, President and Chief Operating Officer, The Cigna Group.
Prior to joining Cigna Healthcare, Dr. Flaster served as the Chief Medical Officer for ConcertoCare, led the population health team at Health Catalyst, and held hospital leadership roles at Mass General Brigham. She is a practicing primary care physician at Brigham and Women's Hospital in Boston and earned her M.D. and M.B.A. from Harvard University. Katya Andresen, Chief Digital & Analytics Officer, The Cigna Group, is assuming leadership of the organization's Excellence and Transformation (XT) efforts, which are shaping how customers engage with the company, and driving innovation across digital, service, and clinical touchpoints.
The XT initiatives have already driven several actions to improve access to care, including new digital tools to help Cigna Healthcare customers navigate their benefits and medical costs more easily, and implementing protections to lower out-of-pocket costs for Evernorth's pharmacy benefit customers. Under Katya's leadership, the company will continue to advance a more personalized, seamless, and human-centered experience. Dr. Flaster's promotion comes as Dr. David Brailer, who has served as Executive Vice President and Chief Health Officer since 2022, departs the company.
Dr. Brailer is a physician recognized for his pioneering leadership in health care, and he brought that same passion to shaping The Cigna Group's enterprise clinical strategy and advancing better access to care and better value of care for the millions of people served by the company. Chris DeRosa, Head of Business Improvement and Innovation, is retiring after serving more than two decades of impactful leadership at The Cigna Group, including President of U.S. Government for Cigna Healthcare. His work has helped expand access to high-quality, affordable care for millions of Americans.
