This has been a busy year in the physician medical group sector. Twenty-two deals have been announced through the first week in April. Four of those deals were announced, quite literally, in the first week of April.

Premier Health, a health system based in Dayton, Ohio, made its fifth acquisition of a health care practice in the past six months. Upper Valley ENT, a two-physician practice in Troy, will join Premier HealthNet, the specialty physician group that is part of the health system. The group now has more than 150 physicians in southwest Ohio.

Right in Premier Health’s backyard, TeamHealth Holdings (NYSE: TMH) acquired Children’s Emergency Services, which provides emergency services for Dayton Children’s Hospital.

Sheridan, the physician services division of AmSurg Corp. (NASDAQ: AMSG), took on North Florida Anesthesia Consultants in Jacksonville. The group’s primary practice site is St. Vincent’s Healthcare System, and it also provides anesthesia for many surgery centers and physicians offices in the area.

Out in Colorado, DaVita HealthCare Partners (NYSE: DVA) announced a deal for Mountain View Medical Group, a 50-physician practice that is the second largest independent group in Colorado Springs.  It operates 14 medical office locations, caring for more than 80,000 patients. None of the deals disclosed financial terms, of course.
