Diagnostics & Behavioral Health

Firefly Autism offers complete diagnostic testing for individuals 18 months to 99+. Firefly Diagnostics & Behavioral Health Services, led by Dr. Rebecca McVey, specializes in the comprehensive psychological testing and evaluation for toddlers, children, and adolescents experiencing a variety of developmental, behavioral, and learning differences. This includes challenges associated with developmental delays, intellectual functioning, learning difficulties, and other developmental disabilities, such as autism spectrum disorders.


Aligning with the latest methods of diagnosis and treatment, Firefly Diagnostics & Behavioral Services recognizes that each individual presents with his or her own unique difference, which is why it has been integrated into our mission statement to ensure each evaluation, diagnosis, and recommendation is specifically tailored to meet the individualized needs of every client.

To ensure the most inclusive assessment of an individual's current functioning, Firefly Diagnostics & Behavioral Health Services employs a multidimensional modality when completing evaluations.

Utilizing data from standardized diagnostic tools along with collateral information from relevant stakeholders (ie parents, educators, doctors, and therapists), Firefly Diagnostics & Behavioral Health Services offers the ability to assess a variety of cognitive, behavioral, and social-emotional domains to best understand the individual's strengths and weaknesses pertaining to the following aspects of functioning:

  • Attention and concentration

  • Verbal and visual memory

  • Auditory and visual processing

  • Visual spatial functioning

  • Language and reading skills

  • Sensory development and sensory integration

  • Gross and fine motor development

  • Social skill development

  • Executive functioning

  • Emotional and personality development

  • Adaptive skills development

The conclusions drawn from the comprehensive psychological testing at Firefly Diagnostics & Behavioral Health Services will guide future clinical professionals, treatment programs, and educational institutions in their ability to develop treatment planning and ensure treatment is effective and efficient.


The dedicated team helps our families navigate the entire scope of care expenses - from obtaining authorizations, if applicable, to scheduling - we strive to make our services as accessible as possible.
