Assisting medical & allied health staff

It is the responsibility of the Medical Staff office to thoroughly review and verify credentialing and privileging information on every applicant. We evaluate the practitioner’s ability, and current competency to provide quality patient care, and minimize risk.  We coordinate activities of the Medical Staff organization, provide support to Medical Staff leadership, committees, and maintain compliance with regulatory agencies.
