I am a Psychiatric Nurse Practitioner (PMHNP) who believes that true and lasting healing happens when we treat the whole person—mind, body, and spirit—not just symptoms. I approach each patient with compassion, curiosity, and deep respect, ensuring you feel empowered to explore your healing journey in a safe and supportive space.
Healing the mind starts with being truly heard. I’m Dr. Joetta Little, DNP, APRN, PMHNP-BC, a board-certified Psychiatric-Mental Health Nurse Practitioner who helps adults navigate a wide range of mental health challenges—from anxiety, depression, and trauma to mood, thought, and personality disorders. My approach combines evidence-based treatment with empathy and collaboration, creating a safe space where every story matters. Whether you’re seeking stability, clarity, or peace, we’ll work together to uncover what wellness looks like for you.✨ Your healing starts here—with care that sees the whole person, not just the diagnosis.
