She is focused on acquiring established sustainability market leaders and purpose‐led companies across diverse sectors, including energy efficiency, green building, organic/natural foods, and healthy living. Diana also is responsible for working with Cranemere’s portfolio companies across all sectors (including industrials and healthcare services) to bring each company to a leadership position on environmental and social performance to drive impact and unlock business value.
