Meet Lina
“A good primary care relationship is supposed to feel boring — you call, I answer, we have a real conversation, and the rest of the system stops being a maze. I read your labs the day they land, I walk every specialist referral end to end, and I tell you what I would do if you were my own family.”

A Physician Who Reads the Note Before You Ask
Before opening Halverson Direct Primary Care, Lina spent five years in primary care at Mass General after internal medicine residency. That experience shows up in how she reads a discharge summary, how she insists on a closed-loop referral, and the way she writes a care plan that the next clinician can actually act on.
Member Stories
“Lina caught a thyroid issue I’d been ignoring for eighteen months in our first intake visit. By the third call she was coordinating with my endocrinologist as if they’d been working together for years. The portal honestly removed about four ongoing tabs from my brain.”David & Hannah C. · Cambridge
