Mercyhealth welcomes clinical psychologist

psychologist, to the staff at Mercyhealth Behavioral Health Clinic, 415-A Congress Pkwy., Crystal

care,” she said. “While I can contribute knowledge on evidence-based practices, patients are the
experts on their own lives. Together, we develop a treatment plan that is individualized and sustainable
so that changes made in therapy can be long-lasting.”

Atlanta.
