I have been a psychiatrist in private practice for 23 years. I believe everyone deserves to be understood. I seek to understand each patient as an individual human being to be able to accurately diagnose mental illness, and deliver the most effective care.
Hi, I’m Sabina Onwonga, DNP, a dual-certified Family Nurse Practitioner (FNP) and Psychiatric Mental Health Nurse Practitioner (PMHNP). I earned my Doctor of Nursing Practice (DNP) from UMass Global University and my Master of Science in Nursing (MSN) from the University of Texas at Arlington.
I provide compassionate, evidence-based psychiatric care and specialize in treating ADHD, anxiety, depression, bipolar disorder, PTSD, and counseling support, helping clients feel heard, supported, and empowered to reach lasting stability and wellness.
Meet Dr. Kwame Frimpong, MD
Psychiatrist | Addiction Specialist | Physician Leader
With over a decade of medical experience, I bring a uniquely broad and deep understanding of both mental and physical health.
I work at the frontlines of psychiatry and addiction care—treating complex cases daily, teaching physicians, and delivering results-driven, compassionate care.
Patients describe me as calm, thoughtful, and genuinely invested in their success.
I am a board-certified Psychiatric Mental Health Nurse Practitioner (PMHNP-BC) providing compassionate, holistic mental health care for individuals across the lifespan. I work with clients experiencing anxiety, depression, ADHD, bipolar disorder, PTSD, insomnia, schizophrenia, and substance use challenges, helping them regain balance and confidence in their lives.
My approach to care is warm, empowering, and collaborative. I believe every person deserves to feel heard, understood, and supported while navigating their mental health journey. I work closely with each client to develop a personalized treatment plan that supports emotional well-being, symptom management, and long-term stability.
With experience in both inpatient and outpatient psychiatric settings, I have supported individuals facing complex mental health challenges and life stressors. I provide comprehensive psychiatric evaluations, medication management, and supportive therapy, while incorporating lifestyle and coping strategies that promote lasting wellness.
I am passionate about helping people develop the tools and understanding they need to take control of their mental health. My goal is to create a safe, judgment-free environment where clients feel comfortable sharing their experiences and working toward meaningful change.
If you’ve been feeling overwhelmed, anxious, or emotionally drained—and nothing seems to be helping the way you hoped—you’re not alone. Many of my clients come to me feeling stuck, exhausted, or unsure of what they need next.
I work with children, teens, and adults who are navigating anxiety, depression, mood changes, and life stressors, and who are ready for a thoughtful, personalized approach to care. I am a Board-Certified Psychiatric Mental Health Nurse Practitioner with over a decade of experience in healthcare as both a Registered Nurse and Nurse Practitioner.
I bring nine years of experience working in the mental health field, supporting individuals through a wide range of challenges with compassion and care. My approach is warm, welcoming, and rooted in creating a safe space where people feel heard and respected. I believe in meeting people where they are and helping them build on their strengths. I strive to help others feel supported, empowered, and hopeful as they move forward.
