Dr. Harper Johnston

I am a child psychologist with over 30 years of experience treating neurodiverse individuals across clinical settings. I have training in Applied Behavior Analysis, Cognitive Behavior Therapy, Trauma-focused CBT, Play therapy, Art Therapy, Drama Therapy, Family Systems Therapy, Floor-time, Collaborative and Proactive Solutions to Challenging behaviors, Parent-Child Interaction Therapy, Universal Protocol, Mindfulness therapy, and Program for the Education and Enrichment of Relationship Skills (PEERS).

Special Experience:

1. Doctoral research (8 years) studying how children with autism learn language

2. Founded an ABA early intervention preschool for immigrants with autism in NYC

3. Consultant within 25+ schools for ADHD/Autism accessibility

4. Adapted a clinical weight management curriculum for neurodiverse teens

5. Qualified as an expert witness for Reactive Attachment Disorder and Autism

6. Coordinating the Autism Spectrum Center at MWPH

7. Created “stoplight” trainings for non-physical de-escalation methods

8. Consult with hospitals and schools on Autism rights/accessibility

I offer a spectrum of treatments that prioritize self-advocacy, consent, and neurodiversity. My goal as your therapist is to minimize the disabling aspects of symptoms so your strengths can flourish. I believe children act out because they are missing skills (which can be taught) or supports (which can be provided). I teach children the foundational skills needed to participate in therapy to bridge the gap between Behavior Therapy and Cognitive Behavior Therapy. My goal is to optimize children’s agency in their mental health goals, across all abilities and needs. If you and your family are ready to commit to your goals, I can help.

How many Psychologists does it take to change a lightbulb?

One...but the lightbulb must WANT to change!

I can teach you mental health strategies, it is up to you to PRACTICE. Families will leave my sessions with handouts and “practice work” so they can use what they learned WHEN they are ready, at their pace. Together, we will make a personalized binder of constructive user-friendly lessons and resources. Children will create their own characters, memes, and social stories based on their individual treatment needs and interests.
