Office: 541-548-6088

I supervise and provide training for the local master gardener program. I work with volunteers to provide community education in home gardening and landscaping. I also provide education to the commercial green industry. 

My main areas of research include educating the community about water-wise gardening including xeriscape techniques, plant selection and plant care.  I also have an emphasis in providing education on fire-resistant plant material and fire-wise landscaping techniques.  A third area of emphasis is regional specific gardening for the Intermountain West including High Desert Gardening and season extension.

I was born and raised in Pittsburgh, Pennsylvania. I have a BS in Biology from Westminster College in Pennsylvania and an MS in Landscape Horticulture from Colorado State University. I have previously worked at the Plant Environmental Research Center and a local nursery in Colorado before moving to Oregon for this position with OSU.  I manage the local master gardener program in central Oregon in Crook, Deschutes, and Jefferson Counties. I provide the training for master gardener volunteers and work with them to provide community education in the areas of gardening, landscaping, and plant problem solving. I also provide education to local green industry professionals including landscape contractors, landscape designers, nursery owners, and growers.
