COVID-19 Message

We hope you are all staying safe and well. We have paused our in-person services and are operating virtually until further notice.

We are currently accepting new therapy clients (ages 10 and up) and new adult clients (ages 18+) for diagnostic assessments (including adult ADHD and adult ASD evaluations). All services are conducted virtually using our HIPAA compliant and user-friendly telehealth platform. All you need is a smartphone, tablet, or computer with access to the internet – no special equipment or downloading an app required.

Please contact us at for scheduling information and questions.
