About Us
At Dr. He's Primary Care for Adults, we are dedicated to providing compassionate and comprehensive adult primary care to the residents of Marlborough and its surrounding towns. Established by Dr. Shunian He over a decade ago with a passion for personalized care, we began as a small practice with just one provider and two full-time staff.
Our unique team-based approach involves close collaboration between our providers and patients, ensuring comprehensive and effective care. We are also committed to continuous learning and staying abreast of the latest advances in medical and pharmaceutical fields, which ensures that our providers' clinical skills are always improving.
Thanks to the trust and support of our patients, we have experienced significant growth—nearly a tenfold increase in patient numbers—and have expanded our provider team threefold. Recently, we moved to our new, spacious office at 28 Lord Road, designed to better serve our growing community.

On behalf of our entire team and the patients she served, we wish her all the best in her future endeavors. Thank you, Chelsea Shafranek, for everything!
