Welcome to Our Practice

Welcome to the pediatric practice of Drs. Mark Gilchrist, Lisa Sevigny, Sheila Galvin, and Anita Shah in Chelmsford, Massachusetts.

In this practice, we have a strong commitment to patient and parent education. We believe that parenting can be more fun and more effective if you are informed and prepared. We believe that an informed patient or parent is a valuable ally in our attempt to provide the best health care. But, no educational material can replace the direct patient care you receive in our office.

Here for you 24/7/365, even evenings!

In addition to extended hours, including evenings, we provide 100% of our own on-call coverage.  That means if you have a question any time, day or night, weekday, weekend or holiday, a member of our clinical staff is always on call to answer your questions!  If you have a medical emergency that cannot wait until we are in the office during regular business hours, the on-call doctor can be reached at 978-988-1888.

Better Communication, Better Care!

• We are a PORTAL based practice.  Lab results and other pertinent information is published to our patient portal for easy access and rapid communication.
• The portal can be used to answer questions and provide additional information, including clearance or excuse notes.
• Often, inquiries generated via telephone will be answered via the portal.  This allows secure and clear communication without impacting busy schedules of parents, patients and staff.
• Patients are encouraged to use the portal for non-urgent questions or to share information in a HIPAA compliant fashion.
• This allows seamless communication that works for both the patients and the staff
• If you are unfamiliar with the portal, or have trouble accessing it, be sure to ask the front desk and they will be happy to get you up to speed!
