Sharon (Xiahan) Zhang
Board Certified Behavior Analyst (BCBA)
Sharon’s passion for working with children with disabilities was ignited in 2019 when she volunteered at an autism rehabilitation center in China, which was part of the Red Cross. After a year of working closely with individuals with autism and other disabilities, she decided to return to the U.S. to pursue advanced education at the University of Washington. Sharon began her professional career providing early intervention services at Seattle Children’s Autism Center, working with families in a clinical setting. She then transitioned to working with reputable ABA companies, focusing primarily on in-home services. Sharon continued her education by graduating from the University of Washington’s Special Education – Applied Behavior Analysis program. She subsequently earned her BCBA in 2022 and has thoroughly enjoyed her work since.
Her professional journey has equipped her with extensive experience in both in-home and clinic settings, where she has demonstrated strong expertise in natural environment teaching, discrete trial training, incidental teaching, and other ABA techniques. Her dedication to the field of ABA is reflected in her continuous pursuit of professional development and her active participation in the ABA community. Outside of her professional life, Sharon loves exploring the nature and traveling. In her leisure time, she also enjoys tending to her garden and nurturing the flowers and plants in her yard.
