Bigy Thomas, MSN, PMHNP-BC

Board-Certified Psychiatric-Mental Health Nurse Practitioner

You deserve a care plan that sees the whole person—not just a 15-minute prescription.

Taking the first step toward mental wellness can feel overwhelming, but you do not have to navigate it alone. I believe true healing happens in a trusted partnership. In our sessions, you will find a safe, non-judgmental space where your voice is heard, your story is respected, and your personal goals guide every decision we make together.

How We Will Work Together:

• Care Beyond Medication: While precision medication management can be an effective tool, it is only one part of healing. I actively integrate evidence-based therapy skills (including CBT and Motivational Interviewing) to help you build practical, lasting coping strategies.
• Mind-Body Connection: With more than 25 years of extensive clinical nursing experience, I look closely at how your physical health, sleep, stress, and lifestyle influence how you feel mentally and emotionally.
• Culturally Sensitive & Personalized: Your background, values, and lived experiences matter. We will tailor your care to fit who you are and what you care about most.

Whether you are coping with anxiety, depression, mood changes, or major life transitions, we will work together at your pace to help you regain balance and feel empowered in your daily life.
