Alyce Benson, LCSW, Karen Weigle, PhD, Amy Rutherford, LPC, S, and Jaime Butler provide therapy and mental health counseling for autistic children, teens, and adults. Our clinicians recognize how a world that is centered around neurotypical populations can sometimes contribute mental health issues in neurodivergent people, including anxiety, depression, social skill deficits, decreased motivation, difficulty transitioning, and relationship problems. We seek to help our clients improve self-advocacy skills as we help them improve their mental health and wellness.

ABA Therapy

The Bridges ABA clinic at the Chattanooga Autism Center offers intensive, clinic-based therapy for children ages 2-8 with behavioral difficulties and/or developmental delays. Under the guidance of a Board Certified Behavior Analyst (BCBA), children receive individualized, play-based instruction that is geared towards kindergarten readiness. BCBAs collaborate closely with caregivers and Registered Behavior Technicians to help children improve communication, build pre-academic skills, engage in social interactions with peers, and gain independence, all the while reducing challenging behaviors at home and in the community. Click this link to review a list of questions you should ask ABA Providers before using their services.

What is Applied Behavior Analysis (ABA) Therapy?

  • ABA is an evidence-based intervention that improves functional outcomes for children diagnosed with autism and other developmental disorders.

  • ABA aims to decrease dangerous or harmful behaviors such as aggression and self-injury by increasing skills such as communication, peer interactions, and engagement in learning activities. 

  • ABA works directly with caregivers to set goals, integrate interventions into home and community settings, and measure progress with the aim of creating life-long change for children and families. 

What does ABA at the CAC look like?

  • Lots of play! Play is the foundation of learning in young children.

  • 1:1 instruction time with therapists in and outside of individual classrooms

  • Frequent breaks in our sensory and calm down rooms to move and relax

  • Structured peer play where children practice social goals in a supportive setting

  • Group instruction via circle time where kids build kindergarten readiness skills such as engaging in group learning, sharing materials, and participating in collaborative projects

Who would benefit from ABA at the Chattanooga Autism Center? 

  • Children exhibiting behavior problems that significantly impact family life

  • Children with language and other developmental delays

  • Children who need more support to achieve kindergarten readiness than is typically provided in a traditional preschool setting

Autism Assessments (waitlist full)

Autism assessments are provided by Karen Weigle, PhD. Dr. Weigle uses the Autism Diagnostic Observation Schedule, second edition (ADOS-2) and other diagnostic tools. The ADOS-2 is a standardized observational assessment of an individual’s communication, socialization, and play/creativity along with other behaviors characteristic of Autism Spectrum Disorder. The ADOS-2 has many different modules depending on the client’s verbal ability and age and is appropriate for ages 12 months up to any adult age. The results of the assessment are provided to the client in a detailed report.  

What does an autism assessment look like?

The assessment usually takes place over four visits. The first visit is an intake session where the caregiver/s and/or individual being assessed answer questions, complete informational forms, and are established as a client. The client is then scheduled for two assessment sessions on different days to allow for a broader sample of the client’s behavior. Each assessment session usually lasts between 40 and 50 minutes. The psychologist then scores the assessment and writes a detailed clinical diagnostic report. The parents and/or client attend a final follow-up session where the psychologist delivers the report, explains it in detail, answers questions, and discusses relevant referrals and future plans. 


Do I need an assessment before getting other types of services?

No! Individuals can seek and receive treatment while they are on the waitlist to be assessed. For example, if a child is demonstrating delays in speech or social skills or is experiencing sensory issues, anxiety, or behavior problems, parents should seek specialized therapeutic treatment immediately. Therapists such as counselors, Speech and Language Pathologists, Occupational Therapists, and ABA therapists will provide their own specialized evaluations and begin treatment. You DO NOT have to wait until after an autism assessment to seek therapy. The main purpose of the ADOS-2 assessment is to provide a diagnosis as well as a detailed professional report, but is not a prerequisite for services in most cases.

Individuals seeking an autism assessment should contact the CAC at 423-531-6961, opt 0 AND contact other places on this list of local evaluation providers.
