Hi! I'm a dual-certified Psychiatric Mental Health NP from Johns Hopkins University (2020) & Family NP from UT Austin (2017), a veteran flight nurse, as well as a certified Yoga instructor & Reiki practitioner. I practice Integrative Psychiatry—merging best practices from Eastern & Western Healthcare for a truly holistic approach. I help adults grappling with mental health challenges to reclaim their life, fostering overall health & mental well-being.
I’m Dr. Emem Nkanga, Doctor of Nursing Practice. I believe that everyone deserves a personalized and compassionate approach to mental health care. I bring over 20 years of experience in healthcare, with a focused dedication to psychiatry over the past 4 years. My passion lies in supporting mental health and emotional well-being.
I work with children ages 10 and above, adolescents, and adults from diverse backgrounds who are experiencing challenges such as anxiety, depression, ADHD, PTSD, bipolar disorder, OCD, insomnia, and more.
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.

My clinical decisions are grounded in current research, best practices, and your individual needs.
I believe in a collaborative and transparent treatment process. I value open communication. I want you to feel comfortable discussing your symptoms, concerns, and goals so we can work together to create a plan that truly supports your mental health.
