Dr. Michael Ciampi took over his father's practice, located in the home on Stevens Avenue in Portland where he and his five siblings were raised, in 1999. Back then, he was one of many independent doctors in Maine. That changed a decade ago when Ciampi moved his practice to a facility run by an offshoot of Mercy Health System of Maine, parent to Mercy Hospital. Ciampi's father recommended the move as a way to relieve Ciampi of the burdens of running a practice, from billing paperwork to nonexistent paid time off.
