Services
Psychological Assessment
Our comprehensive psychological assessments identify learning disabilities, ADHD, and emotional challenges through standardized testing. We evaluate cognitive patterns, academic performance, and social-emotional functioning to create personalized intervention strategies. Clients receive detailed reports with actionable recommendations for educational accommodations, workplace adjustments, and mental health support.
ADHD Evaluation
Specialized ADHD assessments combine clinical interviews, behavioral observations, and neuropsychological testing to diagnose attention-deficit/hyperactivity disorder. We assess executive functioning, impulse control, and attention patterns across multiple settings. Results include evidence-based treatment recommendations for medication management, behavioral interventions, and academic accommodations.
Gifted Assessment
Our giftedness assessments measure cognitive abilities, academic achievement, and creative potential to identify exceptional learners. We use standardized intelligence tests alongside observational analysis to determine eligibility for enriched programming. Families receive guidance on educational planning and strategies to support gifted children's unique social-emotional needs.
Autism Spectrum Screening
Comprehensive autism evaluations utilize diagnostic tools like ADOS-2 and clinical observations to assess social communication skills, repetitive behaviors, and sensory processing patterns. Our team provides differential diagnoses and connects families with specialized support services, including speech therapy and social skills training programs.
Executive Functioning Analysis
This assessment focuses on organizational skills, time management, and self-regulation abilities through task-based evaluations and behavioral checklists. We identify specific executive functioning weaknesses affecting academic or workplace performance and develop targeted intervention plans incorporating technology tools and compensatory strategies.

I can only speak for the therapist I had but she was a poor listener. Kept trying to override my views with her own views. Then was frustrated and rude in the very small amount of time I was there. I left after the 2 session....

Report
I highly recommend Cornerstone Psychological Services if your child requires a psycho-educational assessment in order to determine learning exceptionalities etc. Right from the start, my husband and I felt well-informed about the services that were being provided and we were sent information detailing the entire process from start to finish, including a breakdown of scheduled fees. Katrina was readily available to answer any questions or concerns. Dr. Katelyn was very warm and bubbly with our son and he immediately developed a comfortable rapport with her. She was thorough, in depth and was patient

If your child needs a psychological test, the people at Cornerstone are highly trained, detailed and attentive, and professional to a high degree. This is a costly but important service well delivered. My son recommends it because he approved of the prize he received for completing the tests! :-)
