I am a seasoned clinician and have worked in several outpatient and residential settings with diverse client populations, with a particular interest in geriatric, special needs and LGBTQ+ communities. I attended Earlham College and the University of Pennsylvania, where I earned a Masters in Social Work in 1993. Often, I utilize cognitive behavioral therapy, narrative and humanistic therapy in my work with clients. I believe in the ability of each individual to grow and make lasting changes.
I’m a board-certified psychiatric nurse practitioner specializing in ADHD, mood disorders, and complex or unclear diagnoses. My approach is collaborative but direct - I focus on getting the diagnosis right and creating a treatment plan that truly fits your life.
I have experience across outpatient and residential settings, and I often work with patients who are looking for more clarity or haven’t found answers elsewhere.
My goal is to help you better understand your symptoms, feel more in control, and move forward with confidence.
Hello, I’m Dr. Lisa Merritt, a board-certified Psychiatric Mental Health Nurse Practitioner (PMHNP-BC) and Doctor of Nursing Practice (DNP). I specialize in mental health care for children, adolescents, and adults, and I’m passionate about creating a safe, supportive space where individuals feel heard and respected.
With a background in both clinical leadership and community-based care, I focus on treating the whole person, addressing mental health, substance use, and the social factors that affect well-being. Whether you're seeking support for anxiety, depression, trauma, or life transitions, my goal is to work alongside you to find realistic, compassionate, and evidence-based solutions.
I look forward to supporting you on your path toward healing and growth.

Hi, I’m a licensed clinician committed to creating a warm, supportive, and nonjudgmental space where clients feel comfortable being themselves. I work with individuals navigating anxiety, depression, emotional regulation challenges, trauma, life transitions, and relationship concerns. My approach is collaborative and strengths-based, integrating evidence-based practices including Dialectical Behavior Therapy (DBT), mindfulness-based interventions, solution-focused therapy, and trauma-informed approaches, while also providing clinical and forensic evaluation services. My goal is to help clients feel supported, understood, and empowered in their growth.
You bring your goals and strengths and I’ll bring a fresh perspective and tools that empower. Integrating mindfulness, creative arts, or your spiritual practices enhances my pragmatic, behavioral approach. Bonus: Free weekly women’s virtual group forming.
After 20 years of experience in this field, I utterly believe the mind is a gift, and cultivating it becomes the ultimate task of our lives. Being happy seems to be harder these days and getting to know oneself is not an easy job. Ultimate observation and further inquiry into our minds is the best practice to become closer to who we truly are.
