Dear PGUSD Families,

Since the arrest of Mr. Andrew Chyo yesterday by the Pacific Grove Police Department, we have had the oppurtunity to research his volunteering and employment history at PGUSD. We feel that it is importamt to share the various roles that Mr. Chyo played in our school district so that you may be more informed regarding his contact with our students, families and staff.

Mr. Chyo was employed by the District in roles that included high school tutor, instructional assistant at both Pacific Grove Middle School and Pacific Grove High School, assistant Pacific Grove High School athletic coach, and short term hourly work supporting school staff at high school functions. He was employed durign specific periods between 2015-2021 school year.

As we said in our communication yesterday, any person wanting to volunteer for, or seek employment with, the Pacific Grove Unified School District is fingerprinted and cleared through the Department of Justice. We review those reults to ensure that employees and volunteers do not have any sort of conviction that would disqualify them to work with children in a school district.

Student and staff safety are always our greatest priority. We strive to improve our practices every year so that we may create as safe an environment as possible for our students and staff. We appreciate any input that you might have to assist us in this effort.

We encourage you to take the time to speak with your students regarding these details, as appropriate, especially if they have had contact with Mr. Chyo. If you are a vicitm, or have any additional information regarding this on-going investigation, please contact the PG Police Department at (831) 648-3143, the Anymous Tip Line at (831)-648-3159, or
