Early Days Autism Center
The Group-Based Early Start Denver Model
The Group-Based Early Start Denver Model (GESDM) is an adaptation of ESDM designed for group settings, allowing children with Autism Spectrum Disorder (ASD) to receive intervention within community programs.
Implemented and studied at La Trobe University in collaboration with Dr. Sally Rogers’ team—including Dr. Giacomo Vivanti and Dr. Cynthia Zierhut Ursu—GESDM integrates social learning opportunities with individualized support.
Why GESDM?
- Encourages peer interactions and cooperative play.
- Provides natural opportunities for communication development.
- Supports educational and social goals in a structured group setting.
- Enables treatment in existing community centers.
Inclusion in Community Preschools
Through inclusion programs, children with ASD participate in regular preschool classes like any other student.
Each child is supported by an Instructional Assistant (IA) who helps them navigate daily routines, engage with peers, and practice social skills. Teachers and IAs facilitate small playgroups within the classroom, creating structured learning opportunities tailored to each child’s developmental goals.
These inclusive settings provide meaningful, natural opportunities for social growth while ensuring individualized support.
Implementation at Early Days Autism Center
At EDAC, we are committed to expanding GESDM programs in Sacramento and the Bay Area while fostering partnerships with similar initiatives worldwide.
We believe peer models are crucial for social development, just as they are for all children.
Partnering with Every Child, EDAC founded Every Child Bay Preschool in El Cerrito and Every Child Oaks in El Dorado Hills.

Parent Coaching Playgroups
Parent Coaching (P-ESDM) playgroups provide evidence-based coaching on ESDM strategies. The group setting allows parents to share and learn together while establishing community connections. Children enjoy group activities and peer play while parents support their participation.
EDAC groups are currently running through Every Child Oaks and Every Child Bay.
Participation and Belonging
Individualized Support Within the Classroom Community
In this program, children with Autism Spectrum Disorder join regular preschool classes alongside their peers. Each child is supported by an interventionist—an Instructional Assistant, or IA—who facilitates participation in daily routines, encourages play with classmates, and guides the practice of social skills.
Children take part in classroom activities alongside their peers, fostering a sense of belonging and inclusion.
To further support learning in an inclusive environment, the IA or classroom teacher organizes small playgroups. These groups are carefully structured to provide tailored learning opportunities aligned with each child’s individual needs and developmental goals.
This controlled and personalized approach helps every child participate, learn, and build meaningful connections with peers.
