Emerson Health Surgery

We have a new name! Walden Surgical Associates is now Emerson Health Surgery. We are a comprehensive general surgery practice located on the Emerson Hospital campus in Concord, Massachusetts. Our skilled general surgeons — Atif Khan, MD, FACS; Elizaveta Ragulin Coyne, MD, FACS; Christopher Schlieve, MD; and Alexandra Columbus, MD, FACS — and our nurse practitioner Suzanne Roberts, MSN, FNP-BC, perform a variety of procedures, including abdominal and intestinal surgery, breast surgery and melanoma surgery.

We are committed to delivering high-quality surgical care. Our staff is here to help you throughout your surgery experience, which begins with communicating clearly as we make every effort to accommodate your schedule and help coordinate any necessary testing. Our surgeons are often called upon to see emergency patients within 24 hours, and are frequently able to do so.
