About Hollowell Health

Physician-owned.
Patient-focused.

Founded in 1998 by a group of eight primary care physicians in Alpharetta, Hollowell Health has grown into one of North Atlanta's largest independent physician-owned medical groups — with over 120 physicians across 18 specialties and three ambulatory surgery centers.

Unlike health system-employed practices, Hollowell Health physicians are owners. That means clinical decisions are made by physicians, not administrators — with your care as the only priority.

NCQA Patient-Centered Medical Home recognition at all eight clinic locations — the gold standard for coordinated, patient-centered primary care.
All three ASCs are Medicare-certified and accredited by the Accreditation Association for Ambulatory Health Care (AAAHC).
Unified eClinicalWorks EHR across all clinics and ASCs — every Hollowell physician sees your complete medical record.
