Hi! I am Shea, a Board Certified Nurse Practitioner.
PMHNP-BC, FNP-C with 10+ years of clinical experience delivering evidence-based psychiatric care across outpatient,
IOP/PHP, lifespan and telehealth settings. Skilled in crisis management, behavioral assessment, therapeutic techniques, outcome
measurement, and telehealth strategy, collaborating with multidisciplinary teams to improve patient engagement and treatment
adherence. Focused on mentoring clinicians, implementing quality improvement initiatives, and expanding access to
compassionate, measurable mental health care.
I’m a board-certified Family Nurse Practitioner, Psychiatric Nurse Practitioner, and Nurse Educator with more than 22 years of experience in nursing—including end-of-life care, wellness, and mental health.
My approach is holistic and person-centered. I believe healing happens when we care for the body, mind, and soul together. Whether that includes faith-based principles, mindfulness, or evidence-based clinical care, I meet each client where they are and support their unique path to healing.
While my practice is Christ-centered in philosophy, it is open and inclusive to people of all backgrounds and beliefs. My focus is on helping each individual find peace, clarity, and wholeness by addressing the deeper roots of emotional and physical distress.
I see my role as a partner in your journey—helping you reconnect with yourself, understand your needs, and move toward a healthier, more balanced life from the inside out.
I am Mary Nganga, a PMHNP-BC in state of Texas. I have more than 12 years of experience in mental health.
