Kent, Ohio – The Davey Tree Expert Company is proud to announce the appointment of Thomas Whitney, Ph.D., to technical advisor within the Davey Institute. 

In his new role, Whitney will work with Davey’s offices in the Pacific Northwest and Western Canada. His work will focus not only on Residential and Commercial (R/C) offices but will also actively address needs of other service lines.

“Thomas has a great deal of knowledge in the green industry and will be more than able to provide science-based solutions for Davey clients and shareholders,” said A.D. Ali, manager of technical services, Davey Institute. “I look forward to seeing the value he creates for our service lines.”

Whitney holds a bachelor’s degree in biology from Gonzaga University, a master’s degree in entomology from the University of Kentucky and a Ph.D. in forestry and natural resources from the University of Georgia.
