Zakkary Zander

Air Quality Technician

Hello, I’m Zakkary Zander. I was the Wetlands Specialist for Mashkiiziibii Natural Resource Department for 2 years; I have now switched positions to the Radon Program Manager/Air Quality Technician. I’ve been in the area for the last 10 years; I moved here to attend Northland where I earned a BS in Biology. My goal as the Air Quality Technician position is the same as it was in the Wetlands Specialist position – to help the community to the best of my ability. I will be conducting radon monitoring and performing indoor air quality inspections. In addition, I’m able to provide recommendations for homes and buildings on the Bad River Reservation and can provide educational outreach on indoor air quality topics.
