Bipolar disorder therapists & psychiatrists in Amarillo, TX

Hello, I’m Henrietta Pieh, MSN, APRN, PMHNP-BC, a Board-Certified Psychiatric Mental Health Nurse Practitioner. I provide compassionate, patient-centered care to individuals across the lifespan through comprehensive psychiatric evaluations, medication management, and supportive collaboration.

My background includes years of nursing experience in inpatient psychiatry, crisis stabilization, addiction recovery, and geriatric mental health. I believe in meeting clients where they are, building trust through empathy, and working together toward meaningful progress and emotional well-being.

Whether you are navigating stress, depression, anxiety, trauma, or other life challenges, my goal is to create a safe and supportive space where you feel heard, respected, and empowered in your healing journey.

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.

Compassionate Care for all patients in a therapeutic and safe manner

I have a very mellow, approachable style, and my main goal is to help my patients reach their goals. Many of the people I work with feel like they haven’t been truly heard before, or that medication was presented as their only option. I take time to listen and make sure you feel comfortable, understood, and involved in your care. I also grew up in an immigrant household, where mental health wasn’t always talked about or seen as an option, and that experience really shaped how I work with my patients today.

Are you feeling stuck, like you are caught in endless patterns and struggling to move forward? Life is too short to live trapped in anxiety/depression, unhealthy relational patterns, overwhelming fear, and/or trauma wounds from the past. I help you to identify the root cause and be free from those burdens that bog you down to live the life you want, discover peace, find joy & live better. I am here to walk with you each step of the way as together we navigate the path forward.
