We’re excited to welcome you to our practice.

Located in the rural heart of New Hampshire, Mid-State Health Center is committed to providing innovative, top-notch primary care with a patient-centered approach. Our aim is to help the residents of our communities lead healthier lives while making the most of their healthcare resources. At Mid-State Health Center, our mission is simple: to offer quality primary healthcare to all members of our community, regardless of their ability to pay.

We believe in treating the whole patient, not just their symptoms. Through our medical home model, we’ve seen improvements in health outcomes, cost reductions, and increased satisfaction among patients, families, physicians, and staff alike.

As a healthcare provider serving everyone, regardless of their ability to pay, Mid-State is deeply rooted in our civic duty. What sets us apart is our unwavering commitment to one guiding principle: doing what’s best for the patient.

Our dedication to our patients extends beyond the clinic walls to our entire community. Our staff is dedicated to the well-being of everyone, not just our patients. We actively involve community leaders in the governance of our practice through our Board of Directors, and we encourage our professional staff and employees to participate in various community activities.

We invite you to come and see our practice, meet our team, and join us in taking charge of your health.
