When we met Allina, we correctly guessed that she subscribed to Popular Mechanics when she was growing up (we missed Popular Science but that’s true too). Allina received her BS in Mechanical Engineering from Cornell University and her MS in Aerospace Engineering from University of Southern California. After working as a mechanical engineer for a large mechanical contractor and then a data center developer, Allina received her MBA from Boston University's Public and Nonprofit Management program, with a Concentration in Energy and Environmental Sustainability, in order to better align her career with her values. At Re:Vision, Allina meshes her engineering background with her passion for more sustainable buildings and communities.
