Tina Tarver, Director of Bayside ABA.A Message from the Director of Bayside ABA

Tina Tarver, Director
Board Certified Behavior Analyst
Speech Language Pathologist

Tina was fortunate enough to collaborate with a behavior analyst and CBT while providing speech and language services for a child diagnosed with autism spectrum disorder (ASD). The results were life changing for this child and Tina. This drew her to the University of Washington Autism/BCBA program where she connected with Dr. Nancy Rosenberg, BCBA-D. Through their conversations, it became apparent that speech and ABA fit together extremely well and Tina furthered her credentials to become a BCBA in order to train and supervise Behavior/ABA specialists.

Following this experience and working in the field with many children and families affected by ASD in the Seattle area, she had the desire and experience to expand services to the autism community in her own practice in both Bellingham and Seattle locations. Tina enjoys providing a fun and supportive environment for her employees and clients to work, learn, and grow.
