“As Quinbrook grows, we have been working to establish a leadership structure that further empowers our people to lead our firm into its second decade and beyond. As Co-Founders, Rory and I are proud of what we’ve built together since establishing the firm in 2015. We believe this new leadership structure equips Quinbrook with exceptionally talented leaders as we continue our journey as a value-add specialist in the energy transition.”
