ADHD Testing and Therapy by Licensed Psychologists
Are you or your child struggling to focus, stay organized, or manage daily responsibilities? You may be dealing with Attention-Deficit/Hyperactivity Disorder (ADHD) — a common, often misunderstood condition that affects both children and adults.
At Brookside Therapy & Assessments, we offer comprehensive ADHD assessments and evidence-based ADHD treatment for kids, teens, and adults. Whether you’re a parent looking to support your child or an adult seeking clarity and tools for better focus and functioning, we’re here to help.

-
ADHD assessments for adults, teens, and children

Clear diagnostic feedback and personalized reports
-
ADHD therapy and coaching grounded in best practices
-
Expertise in identifying ADHD in gifted, high-performing, and late-diagnosed individuals

-
A neurodiversity-affirming and strengths-based approach

What’s Included in an ADHD Assessment?
Our comprehensive ADHD evaluations include:
-
A detailed clinical interview with the client (and parents, for child cases)
-
Behavioral and developmental history
-
Standardized ADHD rating scales and cognitive screening
- Review of school, work, or medical reports (when available)
-
A clear diagnosis (if criteria are met), with a formal report and tailored recommendations
-
A feedback session to explain results in an accessible and practical way
We assess for both inattentive and hyperactive-impulsive symptoms, as well as executive functioning challenges, and screen for related conditions (e.g., Autism Spectrum Disorder, anxiety).
