Moira Lewis Pileggi, MS, CCC-SLP, is a licensed and ASHA-certified speech-language pathologist at Marcus Autism Center. As a part of the assessment and diagnosis team, Moira leads communication assessment procedures in longitudinal research designed to investigate early emergence of autism spectrum disorder (ASD) among infant siblings. Moira is also teaching in the Georgia State University Department of Communication Disorders, providing clinical supervision and training to graduate speech-language pathology students. Moira received her master’s in communication disorders at Miami University and completed her clinical fellowship at the Yale Child Study Center.

Following her clinical fellowship, Moira worked as a speech-language pathologist at the Yale Child Study Center in the Developmental Disabilities Program, leading social skills training programs, conducting intervention through a novel speech treatment clinical trial, and providing speech and language assessment for research participants from infancy through adolescence. Prior to moving to Atlanta, Moira was a senior speech-language pathologist at the YAI Autism Center in New York City, N.Y., providing assessment and intervention for children and adults with autism and related developmental disabilities, while also teaching as an adjunct instructor in the Hunter College Special Education Department.

Outside of research, Moira’s clinical work involves conducting provider training throughout metro Atlanta on topics of early autism detection, communication assessment and early intervention models, as well as leading Marcus Autism Center's toddler workshop, a multidisciplinary training series for families who recently received an autism diagnosis.

Moira maintains a special interest in collaboration among multidisciplinary professionals to further understand the early unfolding of autism in toddlers and provide the essential and most appropriate social communication interventions as early as possible to empower families and impact child outcomes.
