    Welcome to ParentSquare

    SHSD is introducing ParentSquare for all school communication, primarily with email, text and app notifications. ParentSquare automatically generates an account for each parent, using their preferred email address and phone number. We encourage parents to access their accounts so they can download the mobile app and update their preferences on when and how they are notified.

    Here’s what you can do with ParentSquare:

    • Receive messages from the school via email, text or app notification 
    • Choose to receive information as it comes or all at once at 6pm daily
    • Communicate in your preferred language
    • Comment on school postings to engage in your school community
    • Direct message teachers, staff and other parents
    • Participate in group messages
    • Complete daily health screening before arriving to campus

Mrs. Stephanie Mateus

As I head into my 2nd year at Pioneer, I'm excited to know more of the kids and their families.  I graduated from Lakes High School in 19XX and attended Oregon State.  I currently live in the Kent-DesMoines area, so it's completely worth the commute to come to work in such a wonderful community.  Science is my passion, and I don't claim to be an expert at any one type of science - I love it all and love the challenge of keeping up with the fast paced changes that happen with the integration of technology and innovation.
