Catherine Williams, PMHNP-BC. Psychiatric Nurse Practitioner (Texas telehealth). As a Psychiatric Mental Health Nurse Practitioner (PMHNP-BC), I am committed to providing compassionate, evidence-based mental health care that supports each individual’s journey toward stability, healing, and lasting wellness. I integrate both medical and therapeutic perspectives to address the whole person—mind, body, and spirit—with clinical expertise and genuine empathy.
I strive to create a safe, respectful, and judgment-free environment where clients feel heard, understood, and supported. Whether you are navigating anxiety, depression, trauma, mood disorders, or major life transitions, I work collaboratively with you to develop an individualized treatment plan that empowers growth and promotes meaningful, sustained emotional well-being.

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.
