Dr Mills is a board certified internist and palliative care specialist with over 35 years of medical experience and practice. He practiced for many years both clinically and with administrative positions at the former Fallon Clinic/Fallon Community Health System. It was here that he built a strong interest in and knowledge of the impact of health care systems and economics on the delivery of care. In these various rolls, he became a strong advocate for physician education to assist the evolution of the care models necessary for success in the developing health care market.

Dr Mills's extensive work in geriatrics in his clinical practice led to his growth in palliative and hospice medicine. Taking on a medical directorship at a local hospice, he gained practical knowledge of this field and went on to complete additional study in this area leading to his successful completion of board certification in 2008. 

He is a zealous proponent of interactive learning processes and enjoys leading/mentoring invigorated medical education forums. He has lectured and taught broadly at both a community/ lay level, medical school level , residency/fellow level and at attending level of audience
