Welcome to My Provider Profile

My name is Geraldine “Geri” Callahan, APRN-BC (Advanced Practice Registered Nurse, Board Certified), and I bring more than three decades of experience in nursing and advanced practice, with a primary focus on adult mental health care informed by a strong medical foundation. I am licensed to practice in both New Hampshire and Massachusetts, and my approach integrates adult and geriatric mental health treatment with medical insight, allowing me to support the whole person with attention to both physical and emotional health.

I work with adults facing a wide range of concerns, including mood and anxiety disorders, chronic pain, hormonal-related mood changes, substance use challenges, and complex medical conditions that impact emotional well-being. I am especially passionate about supporting individuals whose care requires careful listening, thoughtful assessment, and a collaborative approach.

Patients often describe me as compassionate, intuitive, and direct, with a clear, honest approach and a strong commitment to providing the best care possible. I strive to create a calm, respectful environment where patients feel heard, supported, and confident that they have an advocate in their care.

A quote by Leonard Cohen that has long resonated with me reflects how I approach care: “There’s a crack in everything; that’s how the light gets in.” I believe that healing often begins when we take the time to understand the full story behind a person’s struggles. With care, patience, and partnership, change is possible.

If it feels like a good fit, I would be glad to work with you.
