Concierge Medicine
in Massachusetts

Lutanen Health offers private, membership-based concierge medicine in Massachusetts for individuals and families who value time, trust, and a long-term relationship with their physician. Based in Boston, our care model is designed around depth, discretion, and continuity rather than volume-driven visits.

We’ve intentionally built a small, highly collaborative team to ensure every patient receives thoughtful, individualized attention. From our physicians to our health coaches and operational staff, every person at Lutanen plays a vital role in supporting your health journey. Today and for the long run.

We keep our patient panels intentionally small so every member receives unhurried attention and continuous guidance. This allows us to combine modern diagnostics with attentive care, ensuring your health strategy evolves alongside your life.
