Applied Behavioral Analysis Therapy via Early Start Denver Model (ABA Therapy via ESDM)

What is ESDM?
The Early Start Denver Model (ESDM) is an evidence-based comprehensive therapeutic intervention approach for children with or at risk for Autism Spectrum Disorder from 12 to 60 months of age. The ESDM focuses on social interaction skills, in addition to receptive and expressive language, fine motor and gross motor development, imitation, cognition, play skills, and personal independence. Time Magazine has listed ESDM as a Top Ten Health Breakthrough and research has shown that the ESDM changes brain functioning for children with at risk for autism to become more normalized.

It is a child-lead approach that stems from a developmental, holistic approach to treatment. Parental involvement and training are focal points of the treatment and the goal of the program is to encourage social learning during natural, everyday fun activities with the most important people in a child’s life.

Who is eligible for ESDM?
Children between the ages of 12 to 60 months of age who either have a diagnosis of Autism Spectrum Disorder or who show at risk signs of autism are eligible to receive ESDM services.

At risk signs of autism include but are not limited to difficulty with social interactions, including poor eye contact, inability to engage in reciprocal and sustained social interactions with others (including peers), a preference for solitary or parallel play, repetitive behaviors, and/or difficulty organizing behaviors in a variety of settings.

How many hours of ESDM therapy are provided per week?
Therapy is provided at a minimum of 15-hours per week and up to 30-hours per week. In the event that a child is unable to participate in the program at a minimum of 15 hours a week, exceptions can be made based on the scheduling needs of the child and family.

Where is the ESDM treatment provided?
Therapy services may be provided in home, community, preschool, school, and daycare settings based on client need and company availability.

Who funds ESDM?
ESDM therapy is funded by the Frank D. Lanterman Regional Center (FDLRC) for eligible children between the ages of 12 months to 4 years, 11 months of age.

Private insurance companies may also fun the ESDM. At this time, Smile is not a provider of the ESDM through private insurance; however, we plan to become a provider of the program via insurance this upcoming year.

How do I get the ESDM services started?
If your client is between 12 months to 4 years, 6 moths of age and meets the eligibility criteria, a company ESDM representative will call you to discuss further details regarding next steps.

Speech-Language Therapy

The Speech-Language Therapy program at Smile focuses on providing high quality treatment services through natural, everyday learning opportunities. Children in our program are taught the foundational skills of relating (engagement), understanding (receptive language), communicating (expressive language), and speaking (speech production).

Speech- language therapy services may target any or all of the following areas related to effective communication:

  • Receptive Language
  • Expressive Language
  • Fluency Voice
  • Speech Production
  • Motor Speech Disorders
  • Pragmatic/Social Communication Skills
  • Augmentative and Alternative Communication (ACC)

We work hand in hand with parents to help each child master the ever-changing human skill of speech and language. Individualized treatment goals are created and caregivers are taught how to foster their child’s speech and language development during fun-filled, everyday life experiences. The result is lasting communicative success for all treatment participants.

For more information regarding our Speech-Language Therapy program, please contact us at 323.644.9380 or at

Occupational Therapy & Sensory Integration

Smile’s Occupational Therapy & Sensory Integration Program focuses primarily on a child’s motor development, including both fine motor and gross motor skills. Additionally, sensory processing, self-regulation abilities, and self-help skills are supported. Impairments in any of the above developmental areas may be independent of one another but are often interrelated.

  • Motor Development: Motor skill delay is one of the primary reasons that a child may receive Occupational Therapy services. Delays in motor skills can impact a child’s ability to play, interact with others, and/or adequately explore his or her environment. Because of the nature of muscle strength, early intervention has yielded the most successful results when dealing with impairments in motor development. Treatment objectives may include the use of positioning techniques to teach the child how to move horizontally, how to lie on his or her side, to sit, crawl, stand, walk, reach, pull, draw, write, jump, run, and more.
  • Sensory Integration: Sensory processing is a dynamic neurological process of give and take (input and output) between the sensory system, motor system, and behavioral responses that helps us to organize and understand what is going on inside our own bodies and in the world around us.

Each individual has a unique sensory understanding and presents with different styles of interpreting and responding to these sensations. Intake and organization of these various inputs from the surrounding environment help us to initiate motor and behavioral responses that enhance our ability to stay calm, alert, and attentive for continued participation, engagement, and learning within the environmental context (this is also known as self-regulation). Difficulty taking in or interpreting this input can lead to impairments in self-regulation or delays in motor functioning, behavioral challenges, difficulty with social relationships, maintaining mood, regulating emotions, self-esteem, and overall learning.

Motor skill development and sensory experiences are fostered in Smile’s Occupational Therapy & Sensory Integration treatment program through free-play and exploration, as well as in carefully planned and structured learning opportunities. Our occupational therapists focus on providing a child with “just-right challenges” that will help organize his or her motor and/or sensory system and thus helping the child to become more independent in their everyday routines.

Feeding Therapy

Feeding Therapy is a comprehensive feeding therapy treatment offered at Smile for infants and toddlers from birth to school age that experience concerns or delays in feeding. The program provides efficacious treatment of feeding concerns or disorders where a supportive multidisciplinary team assesses the child’s needs, assigns appropriate research driven intervention programs, and supports caregiver education in order to improve the child’s overall feeding skills, behavior, and nutritional intake.

Feeding Therapy at Smile offers individual treatment via a team of licensed specialists including: occupational therapists, speech-language pathologists, pediatric dietitians, child development specialists, and community pediatricians. Caregivers are also considered an integral part of the multidisciplinary feeding team and actively participate in the program, thereby promoting a positive feeding environment for all participants and the generalization of skills.
