We help hospitals provide quality emergency surgical care 24/7/365

A pioneer and leader in the surgicalist movement, SAMGI (Surgical Affiliates Management Group, Inc.)  is setting the standard for surgicalist performance. Founded by surgeons in 1996, SAMGI builds and manages full acute care teams across the nation. We are the only surgicalist organization with published, peer-reviewed results demonstrating long-term excellence in patient care and the ability to improve overall hospital performance. Published in the Journal of the American College of Surgeons, this study demonstrated that SAMGI’s evidence-based, care-standardized programs deliver long-term excellence in patient care and optimize overall hospital performance by improving hospital workflow, efficiency, and patient outcomes.

Today, SAMGI is the leader in providing board-certified surgeons, healthcare providers and medical directors for in-house trauma, acute care, orthopedic, neurosurgery, urology, GI, vascular, and general surgery services for communities and hospital systems. In addition, we also help hospitals implement the emergency services and protocols required to earn designation as an ACS -Verified Trauma Center.


Leadership team

SAMGI’s leadership team is comprised of experts in acute care surgery, trauma and surgical critical care, healthcare management, and legal/regulatory compliance.

This deep experience and visionary leadership foster a highly valued surgeon culture that allows us to establish trusted, meaningful partnerships with surgeons, hospitals, and the communities we serve.
