Therapist Overview

I am a Licensed Professional Counselor of Mental Health working with Delaware Psychological Services at our Newark, DE location. I’ve been working in the field for 10 years and have experience with both inpatient and outpatient settings as well as school based therapy. I work mostly with individuals and families with experience in couples counseling, co-parenting, reunification therapy, depression, anxiety, trauma and grief along with extensive experience working with students with Special Education and mental health needs. I utilize a holistic approach along with Cognitive Behavior Therapy and Mindfulness to get to know each of my clients as an individual so we can best figure out what will be helpful for you to start feeling better.
