Risser Mill Hill was founded by owner Sylance (Sy) Spence.  Sy is from Mount Joy, Pennsylvania and is a graduate of Donegal High School.  She has more than 30 years of experience of working in horticulture.  She has worked in a garden center for at least 30 years, designing wreaths, flower pots, and so much more. She also has a degree from Delaware Valley University in ornamental horticulture.  From all of these experiences she realized there was a need for winterberry growers.  So when she purchased her current home she had a goal in mind to grow and maintain a winterberry farm.  The farm is maintained by Sy, Bert, and the rest of the Spence family.
