Our providers, Dr. Sarah Bortz, DNP, PMHNP-BC, and Dr. Michaela Beaver, DNP, PMHNP-BC, are board-certified psychiatric nurse practitioners who specialize in holistic psychiatry and integrative mental health care.

What Is Holistic Psychiatry?

Holistic psychiatry combines the best of evidence-based medicine with natural and integrative approaches to mental health. Instead of focusing only on symptoms, holistic care looks at the root causes that affect mood, behavior, and well-being—such as nutrition, hormones, sleep, stress, and the gut-brain connection.

At Core Self, our integrative approach may include:

  • Medication management tailored to your unique needs

  • Functional lab testing to uncover underlying imbalances

  • Nutritional and lifestyle guidance for sustainable mental wellness

  • Supplements and natural therapies to support brain and body health

  • Mind-body techniques that enhance resilience and emotional balance
