2024-2025 Board Members
Elsa Harder
President
Elsa joined the Oregon Chapter in the spring of 2018 after graduating from Oregon State University with a Bachelor of Science in Mechanical Engineering. The ACE Mentor Program of Portland planted the seed for working in the building industry, and during her final years of college, she found herself in OSU’s ASHRAE Student Branch and searching for jobs in mechanical contracting firms. Elsa now works as a mechanical designer for Southland Industries’ NW Division. Paying it forward, Elsa hopes to guide more young people to pursue careers related to the built environment by her involvement as a lead mentor for the ACE Mentor Program and the Student Activities Committee Chair for the Oregon ASHRAE Chapter. In her free time, Elsa enjoys listening to podcasts and light adventuring.
