Assessment Process
The assessment process typically takes 4-6 weeks from the intake session to the feedback session.

Intake Session
We will begin with an in-person or virtual intake session to gather background information. We will also discuss the current concerns that you have to ensure an individualized assessment.

In-Person Testing
Next, we will start with two in-person testing sessions. These sessions are scheduled in the morning when you're feeling rested.
​
After testing, I will begin scoring and writing your report.

Feedback Session
Finally, we will end the assessment process with an in-person or virtual feedback session. You will be given a copy of your assessment report and we will review the data from your report together.

Comprehensive assessments can include cognitive, neuropsychological, psychological/emotional functioning evaluations, as well as educational testing, depending on specific needs.
​Psychological assessments provide valuable insights into cognitive functioning, helping people better understand their strengths and areas for improvement. These assessments can identify conditions such as ADHD, learning disabilities, or memory issues, giving people and their families a clearer picture of their mental health. By pinpointing specific cognitive challenges, psychological testing helps inform the development of tailored interventions, therapies, and treatment plans that enhance daily functioning.
Whether you're seeking answers for academic struggles, workplace difficulties, or mental health concerns, engaging in testing can offer crucial guidance, leading to a more informed and supportive path forward.
