# Partner Clinician

## Karla Matheu Sosa, M.A., BCBA, LBA, IBA

## Biography

“With two decades of dedicated experience in Applied Behavior Analysis (ABA), Karla brings a wealth of clinical expertise and a compassionate, holistic approach to behavioral autism interventions. Beginning her career as a behavior technician in 2006, she has since navigated every facet of the field—from direct intervention to leadership oversight. Karla holds BCBA and IBA certifications along with state licensure, but her clinical heart lies in the Early Start Denver Model (ESDM). As a certified ESDM therapist, Karla integrates the ESDM with traditional ABA methodologies to focus on a play and strengths-based, naturalistic approach that prioritizes social engagement and developmental milestones across all domains. Having worked in home, school, community, and center-based settings; Karla is uniquely equipped to support families and help improve their quality of life. Currently, Karla is finalizing her Ph.D. in ABA, focusing her dissertation on advancing the field she has served for 20 years.”
