About Jillian
Trained Where Rigor Is the Baseline
Jillian McNeil is a psychiatric mental health nurse practitioner who earned her Master of Science in Nursing at Regis College and completed her clinical training here at Modern Mentality. That matters more than it might sound: Jillian didn't just train somewhere and arrive. She learned psychiatry inside our testing-first, measurement-based model from day one, with objective diagnostics, validated outcome tracking at every visit, and a collaborative team reviewing complex cases together.
Her practice centers on the three conditions that bring most people through our doors: ADHD, anxiety, and depression. She pairs a warm, unhurried style with genuine clinical discipline, building on comprehensive evaluation rather than assumptions, tracking your progress with real data, and adjusting quickly when the numbers and your experience say something needs to change.
Jillian brings a nursing foundation to psychiatric care, which means she treats the whole person: sleep, stress, physical health, and life context all belong in the conversation. Patients consistently describe her as someone who listens carefully, explains clearly, and makes the plan feel like a partnership rather than a prescription.
"The best treatment plans are built with patients, not for them. My job is to bring the clinical rigor. Yours is to bring your goals. We meet in the middle, and we measure everything."

Areas of Focus
What Jillian Treats
ADHD
Thoughtful stimulant and non-stimulant medication management grounded in Modern Mentality's objective testing, with TOVA and Creyos data informing both diagnosis and treatment response, and check-ins that keep dosing dialed to your real life.
Anxiety
Care for generalized anxiety, social anxiety, and panic that targets the whole picture: precise medication choices when indicated, coordination with our therapy team, and GAD-7 tracking so progress is visible, not vague.
Depression
Evidence-based treatment for depression with PHQ-9 monitoring at every visit, GeneSight pharmacogenetic testing to inform prescribing when helpful, and direct access to NeuroStar TMS through our Duxbury office when medication alone is not enough.
Like every prescriber at Modern Mentality, Jillian works alongside our therapists under one roof, so medication and therapy move in the same direction, informed by the same data.
