Biography

Matthew A. T. Lehman, ILSC, BCEA, LBA, BCBA

Matthew A. T. Lehman, LBA (Nevada #0145), BCBA, BCEA-F, BCPA is the Director of the ABA Group in Las Vegas, Nevada. His work focuses on delivering modern, naturalistic, evidence-aligned behavioral healthcare across home, school, court, and foster systems.

Since 2014, Matthew has exclusively utilized Naturalistic Developmental Behavioral Intervention ABA (ESDM-, PRT-, and JASPER-informed) and does not provide discrete trial training. He received model-specific training, including with a certified ESDM trainer, and has led staff development in these approaches since that time.

His clinical work spans early childhood through adulthood and focuses on complex and system-involved cases, including:

  • Autism and social communication
  • ADHD and executive functioning challenges
  • Anxiety and trauma-related presentations
  • FASD and prenatal substance exposure
  • Severe behavior dysregulation
  • Placement stabilization and family preservation

Matthew integrates ABA with SPACE-informed parent interventions, RULER-informed emotional literacy coaching, and Satter-based feeding dynamics approaches with a focus on preventing unnecessary escalation to higher levels of care.

He has volunteered with the Detention Alternative for Autistic Youth (DAAY) Court since late 2018 and has supported NEAT Court since the program's early formation. He also serves as an Advanced Foster Care (AFC) foster parent in Clark County, Nevada, providing trauma-informed in-home support for youth with high behavioral and emotional needs.

Matthew has presented at the Council of Parent Attorneys and Advocates (COPAA) and Applied Behavior Analysis International (ABAI) conferences and previously served as Director of ABA Services Program / ABA Case Review Manager at Psychiatric Centers at San Diego and later led ABA Behavior Therapies & Testing in San Diego. He has also participated in COPAA advocacy efforts on Capitol Hill and has been featured in the Las Vegas Review-Journal and regional media, including as a guest on David Beinke's "Advocate Late Night," discussing behavioral health, educational advocacy, family stabilization, and foster care.

In addition to clinical practice, Matthew has trained and supervised well over 100 clinicians. Many former trainees now operate independent practices or serve in regional and senior clinical leadership roles.

Primary practice location: Las Vegas, Nevada. Consultation available across select states.
