Sternberg has cultivated and studied trees since 1952 and has assembled one of the largest NAPCC oak genus (Quercus) living reference collections for North America at Starhill Forest, his research arboretum. He and his wife Edie also grow more than 2000 accessioned taxa of woody plants at Starhill Forest. The arboretum is described in the American Association of Museums Directory, the American Horticultural Society's North American Horticulture Reference Guide, and Jacobs' Gardens of North America and Hawaii, and was featured in the 1994 educational film The Greenday Kids Learn About Trees and a 2007 PBS special for Illinois Stories, WSEC TV. It was one of 30 worldwide arboreta featured in the New Trees book compiled in 2009 by John Grimshaw for the International Dendrology Society, and has been dedicated in trust to Illinois College. Guy is one of several experts featured in the upcoming PBS series The Truth About Trees.
He has successfully nominated 51 current or former state champion trees in Illinois, six national champions, and a few more in Texas, Nebraska, and New Mexico, and has worked with the National Famous and Historic Tree Program to promote awareness and appreciation of special and historic trees. He has consulted on tree management for the Illinois Office of the Attorney General, the Illinois Department of Agriculture, the Illinois Department of Military Affairs, the Illinois Capital Development Board, the Illinois Supreme Court, the US Air Force, the National Park Service, and numerous communities. He has traveled widely studying trees and their habitats and participated in educational exchanges with the national dendrology societies of Germany and Belgium, the TEMA Foundation of Turkey, the Kunming Institute of Botany in China, and arboreta throughout North America, Europe, and Latin America.
