O-A-K partnered with Bloomingdale Public Schools to deliver $17 million in bond improvements across the district’s three campuses: Bloomingdale Middle/High School, Bloomingdale Elementary, and Pullman Elementary.

Rather than build new, the district focused on preserving its existing buildings for future generations. That meant investing in roofs, windows, and mechanical systems that improve energy efficiency and lower operating costs.

Work was completed in two series over the summers of 2025 and 2026. Every campus received a new secure entry with a safety vestibule leading into the main office.

At Bloomingdale Middle School, some of the oldest sections in the district received a new roof, energy-efficient windows, renovated restrooms, and security doors at the gym lobby, so the rest of the building can be closed off during events.

Across the district, redesigned parking lots, bus loops, and sidewalks make drop-off and pick-up safer for students and families.

The project scope included:

• Secure entry vestibules and office renovations at all three campuses
• New boilers at all three campuses
• Roofing improvements, including a new roof at the middle school
• Energy-efficient window replacements
• Electrical upgrades at the middle/high school
• Security doors at the middle school gymnasium lobby
• Restroom renovations at the middle school and Bloomingdale Elementary
• Gym painting at Bloomingdale Elementary
• Exterior wall and flooring improvements at Pullman Elementary
• Parking lot, bus drop-off, drive, and sidewalk replacements
• New wayfinding signage
