He has also served Kahuku as Testing Coordinator, Registrar, and COVID Response Handler, and rocked out as the bassist for the faculty band "Keep Your Day Job." (Photo to the left)

Married with a teenage son, Mr. Holtzmann embraces family and community. His favorite quotes are, "Whether you think you can or think you can’t, you’re right" and "None of us is as good as all of us," reflecting his positive, collaborative spirit.
