Chad Johnson, APRN, PMHNP-BC, is a compassionate Psychiatric Mental Health Nurse Practitioner at Nexa Psychiatry & Wellness in Austin, Texas. With more than six years of experience as a psychiatric provider, Chad offers thoughtful, evidence-based care to individuals navigating a wide range of mental health conditions.
Chad earned his master’s degree from Texas Tech University and began his psychiatry career in a private practice setting, where he managed his own caseload and treated patients experiencing anxiety, depression, mood disorders, trauma-related conditions, and other mental health concerns. His approach focuses on understanding each patient’s unique experience and creating personalized treatment plans that support long-term wellness.
Before becoming a PMHNP, Chad spent 16 years working as an ICU nurse in a surgical trauma unit. That experience shaped the way he practices today, strengthening his clinical judgment and reinforcing the importance of calm, compassionate care during difficult moments. It also deepened his commitment to patient-centered medicine and collaborative treatment.
Chad believes mental health care works best when patients feel heard, supported, and involved in their treatment decisions. His goal is to help each person build resilience, improve daily functioning, and move toward becoming the best version of themselves.
Outside of work, Chad enjoys spending time with his family. He has been married to his wife for 24 years, and together they have two daughters.
