Our care team is made up of psychiatrists, nurse practitioners, physician assistants and mental health therapists that are trained to provide compassionate psychiatric and behavioral health care services.
We provide a full spectrum of psychiatric services to adults with varying diagnoses, including but not limited to: depression, mood disorders, anxiety disorders, attention deficit hyperactivity disorder (ADHD), psychosis, dual diagnosis, obsessive compulsive disorder (OCD), panic disorder, bipolar disorder and post-traumatic stress disorder (PTSD). Currently St. Luke’s does not offer dedicated substance use treatment, so we may refer you to community resources that specialize in this kind of treatment.
We offer short-term, solution-focused treatment. You can count on our team of experienced psychiatric and behavioral health specialists to support you with compassion, knowledge, and understanding.
Contact us for more information about our individual and family services.

If you are experiencing a crisis or have urgent treatment-related concerns, contact our office to speak to an on-call member of our team.
If you have non-emergency questions or concerns, please contact our office during established business hours.
