Healing Across the Lifespan: A Partnership in Mental Wellness
Choosing a mental health provider is a deeply personal decision. You aren’t just looking for a prescriber; you are looking for a witness to your story, an expert in the biological complexities of the brain, and a partner in your recovery.
My name is Jessica Stanley, and I am a Board-Certified Psychiatric Mental Health Nurse Practitioner (PMHNP-BC). My journey to this practice has been defined by a unique duality: the macro view of a healthcare executive and the micro focus of a dedicated clinician. Before opening the doors to this practice, I served as the Clinical Director for a large-scale healthcare organization. In that role, I was responsible for the oversight of complex systems, the mentorship of large clinical teams, and the implementation of evidence-based protocols across diverse populations.
While my time in leadership allowed me to impact mental health at a systemic level, my true passion has always remained in the quiet, transformative moments of the exam room. I have returned to full-time clinical practice to bring that high-level expertise back to where it matters most: the individual human experience.
Mental health does not exist in a vacuum, nor does it look the same at age seven as it does at seventy. I specialize in treating patients across the entire lifespan. Whether I am working with a child struggling to navigate their first years of school, an adolescent facing the pressures of identity formation, or an adult managing the heavy mantle of career and family, my approach remains the same: comprehensive, compassionate, and evidence based.
Areas of Specialization
I am trained to treat a broad spectrum of psychiatric conditions including:
ADHD & Neurodivergence
Anxiety Disorders
Depression
PTSD & Trauma Recovery
I am a board-certified Psychiatric Mental Health Nurse Practitioner (PMHNP) with experience in both outpatient and inpatient settings, providing comprehensive mental health care across diverse populations. My background includes extensive work in behavioral health emergency settings, partial hospitalizations, IOP, recovery care, community psychiatric care. I also have experience supporting dually diagnosed patients with co-occurring medical conditions, giving me a broad perspective on the complex interplay between mental and physical health.
I earned my PMHNP degree from Post University and hold PMHNP licensure in both Massachusetts and New Hampshire. Throughout my career, I have remained committed to evidence-based care, while continuously seeking opportunities for professional development and growth in the mental health field.
I am a board-certified Psychiatric Nurse Practitioner with 2 years of advance psychiatric practice and a total of 15 years of experience in healthcare. I specialize in evidence-based care for adults living with anxiety, depression, ADHD, stress, and life transitions, combining thoughtful medication management with practical strategies that help clients build a deeper understanding of their mental health.
In addition to my clinical practice, I am an author and whole-body wellness advocate. My book, BePurBold: A Woman's Journey to Whole Body Wellness, reflects my belief that lasting mental health is rooted in lifestyle, resilience, and whole-person well-being. My goal is to offer a supportive, non-judgmental environment where clients feel heard, valued, and active partners in their own care.
With over 15 years of nursing experience, my passion for psychiatry began early in my nursing career as I witnessed patients transform their lives through healing, self-discovery, and resilience. It is profoundly humbling meeting someone at their lowest point and having the privilege of walking alongside them as they do the work to become their best selves.
I work with adults ages 18 to 60 from all walks of life, with a special focus on individuals who are often overlooked, misunderstood, or silently struggling. Many of the people I work with appear “put together” on the outside—successful, dependable, and strong—while internally feeling overwhelmed, exhausted, or barely holding it together.
I was born and raised in Boston, Massachusetts, to immigrant parents from Haiti, and my cultural background plays an important role in who I am as a provider. Being deeply connected to both Haitian and American cultures has given me a broad perspective and a deep appreciation for cultural identity, family systems, and the shared human experience. At the core, struggle looks very similar across cultures—and everyone deserves care that is respectful, culturally responsive, and compassionate.
Life can look “fine” on the outside while still feeling overwhelming internally. Hi! I'm Mary and I am a Doctorally prepared nurse practitioner, mom and first responder wife. I have over nine years of experience supporting individuals through life’s most vulnerable moments and as a dual board-certified Psychiatric Mental Health and Family Nurse Practitioner, I take a thoughtful, whole-person approach to care.
I work with adults experiencing anxiety, depression, ADHD, mood symptoms, and cognitive changes, often during periods of high stress or hormonal transition. My approach looks at the full picture including mental health, sleep, metabolism, and overall well-being to develop personalized treatment plans. I combine medication management with practical strategies to help you feel more balanced, focused, and in control.











Headway makes it easy to find support for your mental health — from finding the right provider, to understanding costs, to scheduling with ease.
Finding psychiatrists in Plymouth starts with knowing what type of mental health care fits your needs. Psychiatrists and psychiatric mental health nurse practitioners can diagnose mental health conditions, prescribe medication, and manage medication over time. Therapists provide talk therapy and support through approaches like cognitive behavioral therapy, skills-based therapy, and other care models. If you are looking for support with anxiety, depression, ADHD, bipolar disorder, OCD, or medication management, review each psychiatrist’s listed specialties, training, and approach before booking.
Plymouth is a smaller local market, so the right match may not be limited to an office close to home. Virtual psychiatry can expand your options while still giving you access to licensed psychiatrists in Massachusetts. Medication management appointments are often shorter and less frequent than therapy sessions, though some psychiatrists also offer therapy. Some people work with both a therapist and a prescriber. As you compare Plymouth psychiatrists, look at appointment availability, whether they are accepting new patients, and whether their bio gives a clear sense of how they communicate and structure care.
Psychiatric care in Plymouth can be a significant expense without insurance. Using in-network coverage is one of the most reliable ways to reduce session costs and make care easier to plan for. Headway helps you find psychiatrists who accept your insurance, shows estimated out-of-pocket costs before you book, and verifies that listed psychiatrists are accepting new patients with your plan. You can browse profiles, compare specialties and availability, and book directly when you are ready.
If you're already taking psychiatric medication and considering switching providers, talk to your current prescriber before changing or stopping any medication — most psychiatric medications shouldn't be stopped abruptly. Anyone experiencing thoughts of self-harm or in acute crisis should call 988 or go to the nearest emergency department rather than wait for an outpatient appointment.
