What’s Trending in Peoria Unified? The Peoria Unified Family! As we continue to celebrate Peoria High School’s 100th anniversary, we are excited to share what it means to be a part of the Peoria Unified Family. For many, Peoria Unified is filled with family members that they are related to and that they have met along the way. Today, we are joined by two brother, Mike and Steve Treguboff, as they share what it was like to attend Peoria High School and their time working in Peoria Unified.
