Overview
Autism Diagnosis & Assessment in Sugar Land
Founded by board-certified child neurologist Shaun S. Varghese, M.D., this multi-location pediatric neurology group sees patients from newborn through age 26 at clinics in The Woodlands, Katy, Sugar Land, Houston, and San Antonio. Autism spectrum disorder sits alongside epilepsy, ADHD, developmental delay, and genetic disorders as a core focus, backed by a team of pediatric neurologists, DOs, and certified nurse practitioners. The practice uses EEG, MRI, CT, genetic diagnostics, and cognitive testing to evaluate each child individually. Out-of-state and international families are welcome, and all patients are seen regardless of socioeconomic status.
Best for
Families looking for pediatric neurological evaluation — autism, ADHD, developmental delay, epilepsy — who want a multi-location Houston-area group with significantly shorter waits than academic medical centers.
Their approach
Each child receives a personalized evaluation drawing on neuroimaging, EEG, genetic testing, and tools like ImPACT cognitive assessment; findings feed into a detailed care plan coordinated with the family's existing providers. Telehealth extends coverage across all of Texas.
What to expect
Appointments are often available within seven days — compared to three-to-six months at many Houston-area pediatric neurology practices. Commercial insurance, Tricare, and select Medicaid plans (Molina, Texas Medicaid) are accepted; HMO and Medicaid plans require a referral before the visit.
