MEET OUR LEADERSHIP
Bridget Duffy, M.D.
Chief Executive Officer
Bridget Duffy, M.D., is a physician and a former dental hygienist. She was the nation’s first chief experience officer in health care. At the Cleveland Clinic she established the Office of Patient Experience and tied it to measurable results, including patient satisfaction and staff engagement.
She co-founded ExperiaHealth and served as its CEO, then became Chief Medical Officer of Vocera. She was a pioneer in the creation of hospitalist programs and integrative and heart-brain medicine. Throughout her career she has led global conversations on the role human-centered technology can play in protecting the safety and well-being of health care workers, patients, families and communities.
Dr. Duffy became Peak’s CEO in January 2026. Peak is now the first dental services organization in the country to apply a human-centered design framework to the experience of its clinicians and patients. Her premise is that investing in people drives higher quality care and sustainable financial growth. To measure progress, Peak uses the SCORE survey, a peer-reviewed well-being assessment developed at Duke Health and used in more than 30 countries.
Dr. Duffy earned her medical degree at the University of Minnesota and completed her residency in internal medicine at Abbott Northwestern Hospital in Minneapolis. She co-founded the National Taskforce for Humanity in Healthcare and serves on the boards of PathAI, Vital.io and Reel Medicine Media.
“I want dental professionals of all kinds to look at Peak and think, ‘That is a place I’d really like to spend the rest of my career.’”

His ability to align financial strategy with operational goals was a key driver in the firm’s market success.
Prior to that role, Jeff was the CFO at InterDent, a $275 million dental support organization. At InterDent, he led a comprehensive turnaround strategy that overhauled internal workflows and significantly enhanced profitability, ultimately guiding the company through a transaction with H.I.G.
