The primary care practice of three well-known Wilmington physicians has joined Hallmark Health Medical Associates, a member of Hallmark Health System, the leading health provider of north suburban Boston.

Doctors Peter Botchan, Madhavi Challagulla and Natalia Yurkovetsky have been practicing primary care in Wilmington together for more than seven years. Their practice was most recently part of Lahey Health. The practice will remain in the same building at 66 Concord Street, but in newly built patient care space just down the hall in Suite L.

The new practice features many amenities and services for convenience of patients:
• Online appointment scheduling
• On-site labs
• Nearby urgent care services
• Patient portal
• Highly coordinated specialty care
• English, Hindi, Telugu and Russian spoken

"We are pleased to welcome these three very talented physicians to our growing multi-specialty physician group," said Hallmark Health Medical Associates President John O'Hara. "They are an important part of the Wilmington community, and share our commitment to providing the highest quality primary care services locally."

He has served as president of the Internal Medicine Group at Winchester Hospital and was most recently director of Lahey Wilmington. He is board certified by the American Board of Internal Medicine. Dr. Botchan will serve as the practice director of the Wilmington practice. His clinical interests include internal medicine.
