Teresa Omwenga, PMHNP-BC — Maplewood, NJ

Teresa earned her Master of Science in Nursing with a Psychiatric Mental Health Nurse Practitioner concentration from Walden University in 2021. The MSN-PMHNP program built on her prior years of bedside nursing — a foundation in direct patient care that continues to shape how she approaches clinical encounters today. Before graduate school, she worked at the bedside in acute care settings where she saw firsthand how undertreated psychiatric illness intersects with physical health, and how much difference a clinician who listens carefully can make.

Following graduation, Teresa sat for the PMHNP-BC examination administered by the American Nurses Credentialing Center. Board certification means an independent national body has verified her clinical knowledge, tested her against standardized benchmarks in psychiatric assessment and pharmacology, and confirmed that her practice meets established competency standards. In New Jersey, Teresa holds License #26NJ01370900 and practices under a collaborative practice arrangement with a licensed physician — the structure New Jersey requires for advanced-practice nurses who prescribe. She has been in clinical practice for 5 years.

Teresa's primary clinical focus is psychiatric medication management for the mood and attention spectrum. ADHD evaluation and treatment follows DSM-5-TR criteria and validated screening instruments; bipolar disorder management includes both acute stabilization and long-term maintenance planning. Depression and anxiety disorders — including panic disorder and generalized anxiety — are treated with first-line medication approaches aligned with current APA guidelines, combined with supportive therapeutic work in each visit.

For trauma-related conditions, PTSD is managed with evidence-based pharmacotherapy alongside coordination with trauma therapists when appropriate. For OCD, medication management is most effective when paired with Exposure and Response Prevention (ERP) therapy; Teresa coordinates with ERP-trained therapists and manages the medication component of a combined treatment plan. This kind of coordinated split-care approach — where Teresa handles prescribing and the therapist handles structured behavioral work — often produces better outcomes than either alone.

Teresa's geriatric mental health experience includes working with older adults across the aging spectrum, including patients with dementia for whom psychiatric medication management requires particular attention to drug interactions, cognitive side effects, and quality of life. She also provides autism-spectrum medication support for adolescents and adults — addressing co-occurring psychiatric conditions such as anxiety, depression, and sleep disorders that frequently accompany autism. All of these populations are served for patients ages 12 and older.

Psychiatry depends on precision in language — the difference between “I feel sad sometimes” and “I feel nothing most of the time” carries real diagnostic weight. When a patient describes their inner life in a second language, that precision often gets compressed. Words for emotional states don't always translate cleanly, and the vocabulary of distress is frequently culture-specific. Providing care in a patient's first language removes that compression and gives the clinical picture a chance to be accurate.

Teresa provides full psychiatric sessions in Kiswahili for patients from the East African diaspora and any other patient who communicates most naturally in that language. This is particularly meaningful for patients managing stigma around mental health within cultural communities where help-seeking has historically been framed as weakness or private family matter. Having a clinician who shares both the language and some of the cultural context can make a real difference in a patient's willingness to describe what is actually happening and engage fully with care. When you call to schedule, simply mention that you'd prefer Kiswahili — no explanation needed.
