Our Mission

The iTrust Wellness Group strives to provide the highest quality mental health care to our clients in Greenville, SC. Our treatment model is based on wellness. Instead of only focusing on specific symptom relief, iTrust Wellness Group's psychiatric nurse practitioners and mental health specialists seek to improve intellectual, spiritual, emotional, occupational, physical, and social facets of our client's life. Our clinical staff specializes in psychiatry and integrates medication management within our appointments. We treat people from all facets of life, including commercially insured clientele, Medicaid insured, and uninsured. We desire to bring psychiatric and mental health care to everyone, not just a few who can afford it.


Our goal is to help our clients become aware of, and make choices toward, this more successful existence. The team at iTrust Wellness Group thanks you for being a part of this journey with us. We look forward to working with you.

Her goal is to partner with and empower her patients to take control of their lives and achieve their own version of optimal emotional well-being.
