Mental Health Evaluation & Assessment

At Sandbox Therapy Group, our assessment process is designed to be as adaptable and nurturing as the environment of a sandbox. We offer both brief and comprehensive evaluations to understand an individual’s mental health across various stages of life, from toddlers to adults. Our expertise covers a wide range of areas, including autism spectrum disorders, ADHD, OCD, anxiety, bipolar disorder, depression, and other mental health conditions. We are neurodivergent affirming in all our asssessments.


Discover. Decipher. Develop. Decide.

Our journey begins with gathering background information to pinpoint the specific questions and concerns that bring you to us. This initial step guides the selection of appropriate tests, ensuring that our assessment is tailored to your unique needs.

Following the testing phase, we meticulously analyze the results, compiling a detailed report. This report includes not only our findings but also personalized feedback and recommendations for future steps. We are committed to supporting you beyond the assessment, assisting in the implementation of these steps and ensuring continuity of care, which is a cornerstone of our practice.

Reflecting our mission to provide a person-centered, flexible approach, this entire process, from the first meeting to the final feedback, typically spans 4-8 weeks. Our goal is to create a space where understanding your mental health becomes a collaborative, supportive, and enlightening journey.


Psychological Evaluations

While an evaluation or assessment can seem overwhelming and costly, please know we can help explain what is involved. Our goal is to walk you through your options (expedited, brief, or comprehensive) to help you feel supported as well as be able to make an informed decision that (hopefully) does not feel burdensome. Some of the testing we provide are listed below, this list is not exhaustive; please reach out if you have an evaluation you need but do not see on this list.

Developmental, Learning, & Neurodiversity

This assessment focuses on identifying developmental lagging and/or acceleration skills in children and adults. Recognizing the spectrum of neurodiversity, it evaluates areas where an individual may experience delays in cognitive, social, or emotional development compared to typical developmental milestones. The goal is to understand these variations not as disabilities, but as unique aspects of an individual’s neurodivergent journey, providing insights for tailored support and intervention strategies. Common evaluations under this umbrella include (and are not limited to):

  • Autism
  • ADHD
  • Intellectual Disability (Differences)
  • Gifted (2E, Twice-Exceptionality)
  • Obsessive Compulsive Disorder (OCD)
  • Learning Disability (Dyslexia, Dyscalculia, Dysgraphia)
  • Dual-Diagnosis (co-occurring)
Mental Health

The assessment or evaluation focuses on understanding the unique ways individuals may experience and face everyday demands and expectations. Our assessment takes into consideration the heightened sensitivity and unique emotional experiences often found in neurodivergent individuals. We aim to understand the underlying causes and triggers of these behaviors, offering a compassionate, neuro-affirmative approach to support and intervention that respects the individual’s neurological and emotional context. We seek to provide strategies for effective support and engagement. Common diagnoses we evaluation and assess include (and are not limited to):

  • Pervasive Drive for Autonomy (Pathological Demand Avoidance – PDA)
  • Complex Trauma (C-PTSD)
  • Suicidal Ideation (SI)
  • Self-Injurious Behaviors (SIB)

  • Comborbidity with other diagnoses (medical, chronic pain, genetic)
