Bio

Meet Teresa.

I understand the courage it takes to seek help. If you're feeling overwhelmed by life's challenges, or if you're struggling with symptoms of depression, anxiety, or other mental health concerns, you don't have to navigate it alone. My goal is to meet you where you are and provide a compassionate, non-judgmental space where you can begin your journey to wellness. As a Board-Certified Psychiatric Mental Health Nurse Practitioner (PMHNP-BC), I specialize in psychiatric medication management. I work with individuals of all ages to treat conditions like ADHD, bipolar disorder, and dementia. My approach goes beyond medication; I'm here to support you in improving your coping and functioning skills. Together, we'll create a plan to help you feel more in control and better equipped to handle life's ups and downs. I invite you to reach out and take the next step.

Our philosophy

Evidence-led. Compassion-first.

In my practice, the best outcomes come from decisions made together — not handed down. That means I present what the evidence actually says, explain the tradeoffs honestly, and then ask what matters most to you. The American Psychiatric Association guidelines may recommend one path, but your medical history, your life circumstances, and your values get equal weight in the room. Shared decision-making isn't a courtesy; it's how I prescribe.

Every visit uses validated measurement tools alongside plain conversation. For depression I use the PHQ-9; for anxiety the GAD-7; for ADHD the ASRS — and others as your situation calls for them. Numbers track patterns across time and catch changes before you can articulate them. They never replace the conversation about how you're actually sleeping, working, and connecting with the people you care about. Both matter. Neither is sufficient alone.

Because I'm a PMHNP-BC, every visit integrates what other practices split into two separate appointments: medication management and brief supportive therapy happen in the same session, with the same clinician, on the same day. No referral handoffs, no retelling your history. If you want to understand the full framework behind this approach — the seven principles that shape every visit — read the full philosophy on our approach page.

Who we serve

Ages 10 and up, across New Jersey.

We see patients ages 10 and older — children and teens navigating a diagnosis for the first time, adults managing conditions that have been present for years, and older adults including those with geriatric mental health concerns and dementia. Every age group brings its own context, and I adjust the pace and framing of care accordingly. What I don't do is psychotherapy for children under 10; that requires a different clinical training model, and being honest about scope is part of doing this well.

Conditions I work with most often include ADHD, bipolar disorder, depression, anxiety and panic disorders, PTSD, OCD, autism-spectrum medication support, and geriatric mental health including dementia management. If you're unsure whether your situation fits, the free 15-minute consultation is the right first step — I'll tell you honestly if I'm the right clinician or point you toward someone who is.

Care is available in person at our Maplewood office, with telehealth available for New Jersey patients when clinically appropriate — from Newark and Elizabeth to Livingston, Millburn, Chatham, West Orange, and beyond. Sessions are available in English and Kiswahili. If you or a family member is more comfortable speaking Kiswahili, please mention it when you call.

What's different

What makes this clinic different from most.

You see the same clinician every visit.In a larger clinic or telehealth network, you might see a different provider each time — or a care coordinator who relays messages to someone you've never met. Here, Teresa is your clinician at the first appointment and at every appointment after it. The context from prior visits, medication trials, side effects, and patient preferences stays in one continuous clinical relationship.

Prescribing and therapy in a single visit.A PMHNP-BC can do what a split-care practice separates into two appointments: medication review, adjustment, and brief supportive therapy all happen in the same session. You don't need to coordinate between a psychiatrist for medications and a separate therapist for everything else — unless you want to, in which case we coordinate with your outside therapist seamlessly.

Bilingual care — English and Kiswahili. Describing a mental health symptom precisely is hard in any language. Doing it in your second language can mean the difference between an accurate clinical picture and a missed diagnosis. Teresa provides full clinical sessions in Kiswahili for East African diaspora patients and anyone else who communicates more naturally in that language.

New Jersey only.This is a licensed, locally-rooted practice — not a larger practice where patients may meet different clinicians over time. Under New Jersey's collaborative practice arrangement, Teresa works within a defined scope alongside licensed physicians. That legal structure means accountability, not a workaround.

Transparent fees and sliding-scale access. The initial evaluation is $250; follow-up visits are $150. Sliding-scale reductions of 20–50% are available for self-pay patients who need them — no formal paperwork, just a brief conversation on the free consultation. Superbills are provided for out-of-network reimbursement. Eighteen insurance plans are listed for the practice — verification of your specific plan and benefits happens during the free 15-minute consultation before any paid visit.
