Hi, I’m Ngozi Kalu, PMHNP-BC, AGNP-C, a board-certified psychiatric nurse practitioner serving clients across Texas. I provide compassionate, evidence-based mental health care for adults and teens, helping them regain balance and confidence in their daily lives.
I specialize in treating anxiety, depression, ADHD, trauma, and sleep disorders, and other mental health disorders. I also work closely with patients and their families to create treatment plans that fit their unique goals. My approach combines thorough psychiatric evaluations, medication management, and supportive counseling to help you feel better, think clearly, and live with purpose.
Many of my patients come to me when life feels overwhelming, relationships are strained, or focus and motivation seem out of reach. Together, we identify what’s getting in the way and build a clear, personalized path forward.
I believe healing happens when care is collaborative, respectful, and accessible. That’s why I offer flexible scheduling and accept insurance through Headway so you can get started without delay.
If you’re ready to take the next step, I’d be honored to partner with you in your journey toward wellness.
Margarita Rice is a double-board-certified psychiatric-mental health and family nurse practitioner.

As a special needs dad, a former Spanish teacher, former school counselor (MEdSC), and nurse (MSN), I bring a broad range of experiences to my clients. As a nurse, I have worked PACU, ER, and geriatrics. My goal is to work with the client to reach their goals through the use of counseling, supplements, and medication as needed. I enjoy using belief systems as part of my counseling if desired.
Like many providers, I have worked with many clients with depression, mania, and anxiety. As a previous teacher/school counselor, I understand the impact of ADHD on the student, the classroom, the teacher, and the family.
I think it is important for prospective clients to know that I want to help both now and in the future. For this reason, there are drugs that I don't prescribe (stimulants and benzos) because of the long-lasting side effects.
My hobbies include playing the piano, singing, gardening and family.
My clinical style is warm, structured, and collaborative. I emphasize clear communication and shared decision-making with my patients. I strive to create a safe and non-judgmental environment where people feel heard and respected.
I have an AGACNP background, which supports my ability to assess medical comorbidity and understand complex medical/psychiatric overlap. I am also DOT-certified, which reflects my knowledge of safety-sensitive considerations and careful medication risk assessment.
