Yrenka Sunderlin, MS, BCBA, LBA

Founder & Executive Director

     Yrenka is a Board Certified Behavior Analyst (BCBA) with an extensive background working with individuals with special needs. Her path to a career in Applied Behavior Analysis (ABA) started with working in a residential facility (Level 12) 25 years ago. While there, she learned to identify a myriad of challenging behaviors, but observed that the treatment of choice at the facility was not effective in achieving lasting, positive behavior change. She knew that she wanted to make a difference, and that using evidence-based practices, such as Applied Behavior Analysis (ABA), was most likely going to make this a reality. After receiving a Bachelor’s degree in Psychology from the University of La Verne, she then attended California State University, Los Angeles to complete her Master's Degree in ABA under the mentor-ship of Dr. Randy Campbell, Dr. Michele Wallace, and Dr. Henry D. Schlinger, Jr. During this time, she began receiving extensive formal training by Kari Berquist, Ph.D. BCBA-D in ABA methodologies, including Discrete Trial Training, Picture Exchange Communication System, Pivotal Response Treatment, Verbal Behavior, Positive Behavior Support, Functional Communication Training, Functional Behavior Assessments, completed the Autism Certification Program and UCLA PEERS® certification program.  She is a member of the Association for Behavior Analysis International and the California Association for Applied Behavior Analysis. She subscribes to scholarly journals, participates in continuing education opportunities and maintains close ties with a network of professionals in the field.

In addition to being a respected Behavior Analyst, she is currently an adjunct faculty member at National University (Camarillo), teaching BCBA course sequence. She also serves as an Advisory Board Member for Reid's Gift. 

 

In an effort to reach out to the under-served Spanish speaking community, Yrenka provides parent education workshops (in Spanish) at a local resource center in Ventura County.
