About Bull City ELC

We started Bull City Early Learning Center when we recognized the limited availability of early intervention (birth to 5-years) programs in the Triangle area, especially in Durham.  Specifically, we believed our local children need a place with inclusive social skills, school readiness programs, peer models, while utilizing ABA strategies for these young learners. 

Bull City ELC was created to fill the need for high quality, personalized programs for families within the Triangle.


Who We Are:


Tara Vellella

M.A. Applied Behavior Analysis

Board Certified Behavior Analyst BCBA

Certificate in Autism

Tara is a Board Certified Behavior Analyst. She moved to Durham from Los Angeles in 2016 and soon recognized the lack of services in the area for children with special needs.  She has various experiences working with children from 18 months to 18 years old on the autism spectrum, and with sensory processing disorders and other various developmental disabilities.  Her career started with a BA in child psychology, as a 1:1 ABA technician and fell in love with the moments when a child masters a challenging skill; from following a sequence of events, speaking to peers in a group, playing "Match," trying new foods, etc.  These moments led her to pursue her passion and obtain her Master's degree in ABA with a certificate in autism, and then to become Board Certified.

In her spare time, she enjoys baking, playing with her two young children and exploring new places in beautiful North Carolina.
