Dan Mingle, MD, MS
President and CEO

Dr. Dan Mingle’s personal experience owning and operating a small group family practice in rural Maine gave him first-hand insight into many of the problems that plague our health care system, including bureaucratic inefficiencies and ever-increasing costs.

His quest for a better-functioning medical practice and healthcare system led to join the faculty at Dartmouth Medical School’s Family Practice Residency, where he received advanced training in measuring health care performance and leading change in complex medical organizations. He then served in a leadership role in clinical informatics at MaineGeneral Medical Center and sought additional training and practice in Transact SQL. Along the way he developed a national reputation for quality reporting and in 2008 was named one of nine “Innovators of the Year” by Healthcare Informatics magazine.

In 2012, he founded Mingle Health, eager to devote his passions and skills to creating best-in-class products and services designed to help providers and medical organizations thrive in the business and practice of healthcare.
