    Dr. Linda Chalker-Scott

    I’m an associate professor in the Department of Horticulture at Washington State University. I’m also an Extension Specialist in Urban Horticulture, meaning that I have a global classroom rather than one physically located on a college campus. I’m trained as a woody plant physiologist and I apply this knowledge to understanding how trees and shrubs function in urban environments. This is a fancy way of saying I enjoy diagnosing landscape failures—sort of a Horticultural CSI thing. I’m a native Washingtonian, but I spent my academic life at Oregon State University and then moved to Buffalo in 1989 for my first university position. I moved back to Seattle in 1997 and worked at University of Washington's Center for Urban Horticulture. In 2004 I decided to hang up my college teaching robes and began my Extension position with WSU.

    Dr. Bert Cregg

    I am currently an Associate Professor and Extension Specialist in the Department of Horticulture and Department of Forestry at Michigan State University. I’m originally from the great Pacific Northwest; born and raised in Olympia, Washington. I got my B.S. in Forest Management from Washington State University and then did graduate work in tree physiology at Oklahoma State University (M.S. Forestry) and at the University of Georgia (Ph.D. Forest Resources). I began working on tree nursery and urban forestry-related issues with the USDA Forest Service and continued to research tree nursery issues as a scientist with Union Camp/International Paper. Since 1999 I have been on the faculty here are MSU developing research and extension programs that deal with landscape, nursery, and Christmas tree issues. I am currently involved in production issues related to container-grown trees and issues related to the Emerald Ash Borer outbreak.

    Dr. Jeff Gillman

    I’m an associate professor in the Department of Horticultural Science at the University of Minnesota. Officially I work mostly with trees and shrubs, but I’ve also been known to test things like egg shells for stopping slugs, beer for its qualities as a fertilizer, and milk for its fungicidal qualities. I come from a small town in Pennsylvania, just west of Philadelphia, where I first learned about growing trees in my parents’ small orchard. I attended Franklin and Marshall College in Lancaster, Pennsylvania, then earned a master’s degree in entomology and a Ph.D. in horticulture from the University of Georgia. After Georgia I came north to Minnesota.

    Dr. Holly Scoggins

    I’m an Associate Professor in the Department of Horticulture at Virginia Tech and Director of the Hahn Horticulture Garden, our fabulous 6-acre teaching and display garden on campus. I teach Herbaceous Landscape Plants, Greenhouse Management, Ornamental Plant Production and Marketing, and a Public Gardens course. My research focuses on nursery and greenhouse production of perennials. In both sharing my research and in learning what’s new and improved, I interact extensively with the state and regional green industry - growers, plant breeders, landscapers, and garden centers. My B.S. (Agricultural Economics) and M.S. (Horticulture) are from the University of Georgia, and my Ph.D (Horticulture) is from North Carolina State University. Professional credentials aside, I guess I would describe myself as a card-carrying plant dork.
