I grew up in Southern California and left the sunshine in 2017 to move to the Pacific Northwest. I started my career in ABA as a behavior technician in 2013. I decided to pursue a career in ABA when I saw how beneficial it was to the clients and families I served. I received my Bachelors in Child and Adolescent Studies from California State University, Fullerton and my Masters in Applied Behavior Analysis from Ball State University. I became Board certified in 2017. I have experience providing in-home services to children and teens, as well as residential behavior support for adults with various needs. I also enjoy providing parent consultation and staff training. My spare time is mostly spent exploring Washington or spent with my family and friends. I have a dog, Maverick, who gets into everything... despite sharing a home with a BCBA. I am loving all Washington has to offer and am so thankful for my experiences here.

I was born and raised in Washington state. I attended Western Washington University where I received my Bachelors of Arts degree with a focus in Developmental Psychology, Sociology, and Education. While attending WWU, I mentored elementary aged students and tutored students at alternative schools in the community. I have since worked with children and adults with physical and developmental disabilities in schools and in home. Through these experiences, I have developed a unique perspective and skillset that have allowed me to bring about positive change in people’s lives. 

I am excited to bring my insight and skills to my position as a Lead Certified Behavior Technician at The Madrone School. 

In my spare time, I enjoy conquering the great outdoors, spending time with my dog and cat, and reading.
