About Us
Two Exceptional Doctors
One Integrated Approach
Most ABA therapy practices are run by behavioral therapists. That's not us. Autism Centers of Pittsburgh is led by two of the most experienced and respected autism and mental health experts in Western Pennsylvania.
Experience That Speaks For Itself
Unmatched Expertise,
Personally Invested in Your Child
At Autism Centers of Pittsburgh, you're getting two of the most qualified autism and mental health experts in the region, personally invested in your child's success. They don't simply oversee programs from a distance — they're actively involved in your child's care, assessing progress, adjusting treatment plans, training staff, and meeting with families.
Doctors Carosso and Lowenstein provide something not found anywhere else: an interdisciplinary psychological and psychiatric partnership. Both work together to ensure your child receives care that addresses every aspect of their development — behavioral, emotional, medical, and social.
