About Us

Metro Anesthesia Services was formed in 2016 by the collaboration of two Certified Registered Nurse Anesthetists; Christopher J. Gross and Polly C. Sipe because they saw the need for safe Office-Based Anesthesia (OBA). Certified Registered Nurse Anesthetists (CRNA’s) provide safe and effective anesthesia for physicians allowing them to focus solely on the surgery itself. The result is an atmosphere of security and relaxation for both the surgeon and the patient. We take the worry out of anesthesia.

Our Mission

Safe Care in a Convenient Setting

Procedures conducted in an office or clinic provide benefits to both the physician and the patient. Our mission is to meet or exceed the safety standards of an accredited hospital or ambulatory surgical center but in the convenience and comfort of an office setting. We offer a simpler solution to what has become an expensive and time consuming process.

About our Staff

We are a small company and employ only Certified Registered Nurse Anesthetists. Our partners have over 30 years of combined anesthesia clinical experience. We offer anesthesia services to both children and adults. Our advanced practice professionals are highly trained and skilled in administering anesthesia autonomously.
