President, Merrimack Valley Emergency Associates, Inc.

Welcome to Merrimack Valley Emergency Associates!

  We are an independent group of Emergency and Urgent Care Physicians, Physician Assistants and Nurse Practitioners who work in the greater Lowell area of Massachusetts.  We provide Emergency and Urgent Care services at six sites among one hospital system; two emergency departments and four urgent care centers.

We are extremely proud of our highly talented and dedicated physicians and advanced practice providers.  Our goal is to provide exceptional medical care to all that arrive to our emergency departments and urgent care centers.  Our focus is not only on our patients but also on overall health and well-being of our group members as well as supporting individual clinical interests and our member's long-term professional goals.

We are motivated by the challenges of our specialty, the differences that we can make in our community, and the collegial relationships that we enjoy within our group and with other members of the medical staff at Lowell General Hospital.
