Functional Psychiatry for Londonderry, NH

A traditional psychiatric work-up starts and often ends with symptoms: what you feel, how often, and for how long. Functional psychiatry takes a wider view, using targeted testing to look for underlying deficiencies and physiological concerns that may be driving how you think and feel, alongside the standard evaluation. For a lot of Londonderry households, that whole-person approach fits how they already think about their own health. Many families here cross into Massachusetts for work every day and are used to coordinating care between states. No state income tax has drawn a lot of professional, health-conscious families to this part of New Hampshire, and they tend to want a mental health provider who looks at the full picture, not just a diagnosis code.

Functional Psychiatry for people in Londonderry, NH

If you live in Londonderry and have felt like standard mental health care only addresses part of the problem, functional psychiatry is built for that frustration. It does not replace a careful psychiatric evaluation. It adds to it. Your clinician considers thyroid function, nutrient levels, sleep, inflammation markers, and other physiological factors that can influence mood, focus, and energy, alongside your history and symptoms.

This matters for people juggling demanding jobs, long commutes across the Massachusetts border, and family responsibilities, because fatigue, low mood, or anxiety can have more than one contributing cause. A functional approach is designed to look for those causes rather than assume there is only one explanation.

How telehealth care actually works

Harborside Psychiatrics is based in Yarmouth Port, Massachusetts, and delivers care by video to patients across New Hampshire, including Londonderry. You do not travel anywhere for an appointment. You need a private space, a stable internet connection, and a computer, tablet, or smartphone with a camera.

An initial evaluation typically runs longer than a follow-up, giving your clinician time to go through your history, current symptoms, and any prior testing. If lab work is appropriate, your clinician orders it through a local lab near you in Londonderry, so you are not shipping samples anywhere. Once results come back, you discuss them together on a follow-up video visit, and your clinician builds a plan from there.

Follow-up appointments are usually shorter and scheduled at an interval your clinician recommends based on your situation, often every few weeks at first and spaced out over time. If medication is part of your plan, prescriptions are sent electronically to a pharmacy of your choosing in Londonderry or nearby.

What we treat

Functional psychiatry at Harborside is used alongside care for concerns like persistent low mood, anxiety, chronic fatigue that affects daily functioning, and other conditions where physical health and mental health are closely connected. It is one part of a broader evaluation, not a standalone treatment for every condition. Your clinician will talk with you about whether targeted testing makes sense for your specific symptoms before ordering anything.

What the first appointment involves

Your first video visit is mostly conversation. Your clinician asks about your current symptoms, medical history, sleep, diet, stress level, and any medications or supplements you already take. Based on that conversation, they may recommend specific lab testing to check for physiological factors that could be contributing to how you feel. You will understand why each test is being recommended before you agree to it. Nothing is ordered automatically.
