History

Formed in 1970 by Gerald Brennock, M.D., a General Internist, the Mission Internal Medical Group (MIMG) has grown to a 40+ Physician Member Internal Medicine Group that now has 8 sub-specialties of Internal Medicine.

MIMG added the specialties of Gastroenterology in 1972; Cardiology in 1977; and Pulmonary in 1982. By 1987 MIMG had grown to (9) Physicians when it merged with the Viejo Niguel Medical Group, a group of (3) General Internists. Additional candidates were soon recruited in Cardiology, Pulmonary, Critical Care and Gastroenterology. An Endocrinologist joined in 1992 and the medical group had grown to (15) Physicians. At this point MIMG went back on the merger trail and joined with four different small groups offering office-based coverage in the communities of Laguna Hills, San Clemente and Mission Viejo. In addition, MIMG added two additional sub-specialties: Allergy and Geriatrics. By 1995 MIMG had grown to (25) Physicians covering all of South Orange County.

In addition to physician growth, MIMG has also developed diagnostic services to facilitate the efficient usage of time spent by both patients and physicians within the outpatient setting. This was done with the opening of the Clinical Laboratory in 1993; the Nuclear Medicine Department in 1995; and the Endoscopy Center in 1998.

A recent change in healthcare delivery has been the introduction of the Hospitalist. This specialty represents the need to specialize on the unique needs of the patient within the hospital setting. The Hospitalist besides being an experienced Internal Medicine physician also knows the unique internal workings of the hospital environment. This allows him to deliver efficient high quality patient care. In order to cover the patient need MIMG now has (4) Hospitalists on staff.
