A traditional psychiatric work-up asks what symptoms you have and which medication might address them. Functional psychiatry asks a different question first: what in your body might be driving those symptoms in the first place. Harborside uses targeted lab testing to look for nutritional deficiencies, thyroid and hormone irregularities, and other physiological factors that can show up as anxiety, low mood, or brain fog before any prescription pad comes out.
Marstons Mills runs on a different clock than the beach towns around it. It is a year-round village of retirees, families with kids in the Barnstable schools, and people who work the seasonal-business rhythm of the Cape without living the postcard version of it. Harborside is based year-round in Yarmouth Port, on the Cape, and works with people in Marstons Mills who want a mental health approach that accounts for the whole picture, not just the half that fits in a fifteen-minute med check.
Every appointment happens by secure video. You need a smartphone, tablet, or computer with a camera, a stable internet connection, and a private place to talk. There is no waiting room and no drive to Yarmouth Port or anywhere else, which matters if you are coming off a shift, managing a household, or just do not want to sit in a parking lot beforehand.
An initial functional psychiatry appointment runs longer than a standard follow-up, because it covers your history, current symptoms, and a discussion of which labs make sense for your situation. Bloodwork is typically drawn at a local lab near you in Marstons Mills or a nearby town, and results come back to your Harborside clinician for review. Follow-up appointments are shorter and scheduled based on where you are in treatment, often every few weeks at the start and spacing out from there. If medication is part of your plan, prescriptions are sent electronically to the pharmacy of your choice, the same pharmacy you would use for anything else.
Harborside is based in Yarmouth Port, Massachusetts, and delivers this care by video across the state, which is what makes it workable for a village like Marstons Mills that is not exactly on top of a specialty clinic.
Functional psychiatry at Harborside is used alongside, or sometimes instead of, a purely symptom-based approach for concerns like persistent anxiety, depressive symptoms that have not responded the way you expected, chronic fatigue with a mental health component, difficulty concentrating, and mood changes tied to hormonal shifts such as perimenopause or thyroid dysfunction. It can also be part of a broader plan for people already managing attention-related concerns or sleep disruption who want a fuller look at what might be contributing. This is not a replacement for emergency care, and it is not a claim that a lab panel explains everything. It is one more piece of information used to build a plan that fits your body along with your history.
Your first visit is a conversation, not a form. Your clinician will ask about your symptoms, your medical and family history, current medications or supplements, sleep, diet, and stress load. From there, they will talk through which labs, if any, make sense to order and why. You will leave with a clear next step, whether that is a lab requisition, a follow-up date, or a referral within the practice to a therapist on the team if talk therapy would help alongside the medical piece.
Medication management and functional psychiatry at Harborside are performed by psychiatric nurse practitioners: Rachel Egan, RN PMHNP-BC, who is also Harborside’s clinical director, Emily Pardue, RN PMHNP-BC, and Kirstin Ritchie, RN PMHNP-BC. Each is qualified to evaluate, diagnose, and prescribe for mental health conditions, and each brings that training to the functional approach described above, reading lab results alongside your symptoms rather than treating either in isolation. Full bios and credentials for each clinician are on the team page.
Therapy is delivered by Harborside’s licensed therapy team: Hannah Legesse, LICSW, Tori Mahoney, LMHC, Jacquelyn Duford, LCMHC ATR, and Lexie Carchedi, LCSW. If your plan includes both medication management and talk therapy, these two parts of the team coordinate directly on your care.
Harborside is a private-pay practice and does not bill insurance directly for appointments. Current fees for an initial and a follow-up appointment are listed on the pricing page, and questions about cost can be answered before anything is booked.
You can request an appointment online. A member of the team will confirm scheduling, walk you through what to expect, and get you set up with the video platform before your first visit. If you are not sure whether functional psychiatry is the right starting point for you, that is a fair question to bring to the intake call rather than something you need to figure out on your own beforehand.
If you are in immediate danger, call 911. For mental health crisis support, call or text 988. Harborside does not provide emergency or after-hours care.
