Meet Our Founder - Dr. Gia Koehne

Dr. Gia is a Clinical Psychologist licensed in the state of Texas and a Board Certified Behavior Analyst.  Her clinical experience dates back to 2002 when she became a behavior therapist for children with autism soon after receiving her bachelor’s degree in Psychology.  In 2003, she opened and directed a non-profit organization in Puerto Rico that provided applied behavior analysis (ABA) home-based therapy for children with developmental disorders.  She received her formal ABA training from Penn State University in 2005 and an autism certification from Penn State in 2007.  

Concurrently, as she directed her ABA program, Dr. Gia received her doctoral degree in Clinical Psychology from Ponce School of Medicine in Ponce, Puerto Rico in 2008.   Most of her training was focused on psychological and neuropsychological assessments, bilingual psychotherapy, and evidence-based individual therapy for children and adolescents for a variety of difficulties including ADHD, behavior disorders, depression, anxiety, and family conflict.  

Since 2009, Dr. Gia has dedicated her clinical work to the assessment and treatment of developmental disorde​rs through her collaboration with various agencies in San Antonio and through her post-doctoral training with the Center for Autism and Related Disorders.  Her current interests include Pivotal Response Training (PRT) for children with autism spectrum disorders, evidence-based practices for children and adolescents, psychological assessments, naturalistic and peer-mediated interventions, parent training, quality supervision, and bilingual applications of behavioral practices.
