My Approach to Helping

Have you wondered if your child or young adult would benefit from therapy? I offer a phone consultation to discuss any questions you may have and will be by your side to navigate the process. I am a licensed clinician who works well with parents, children, and young adults struggling with anxiety, depression, ADHD, school related, and social issues. My approach is to empower parents. I draw on your child’s strength while building new skills to work through their challenges and learn to become their own therapist. I also provide home-based services and collaborate with schools to support your child\'s success.

I am a Licensed Marriage and Family Therapist with specialized training in Trauma Adolescent Focused Cognitive Behavior Therapy, Multi-Dimensional Family Therapy, and Adolescents with high-risk behaviors. My specialized training in family therapy and working with children in individual, school, and home settings give me a deeper understanding of your child.

Zackson Psychology Group serves high functioning clients of all ages from children, adolescents, adults, parents to executives. Most services are reimbursed by insurance companies. Our clients have challenging schedules, therefore, in addition to business hours, we also offer evening and weekend appointments.
