About Us

As founders and owners of Parkside Orchid Nursery, Tom Purviance and John Salventi have spanned a period of dynamic growth and change in the international orchid industry. They began as hobbyists in 1986 and entered the commercial orchid world as owners of Delaware River Orchids in 1987. In 1992 they created Parkside Orchid Nursery Inc. in Ottsville, PA and operated it as owners/managers for 20 years.  Parkside became one of the most respected orchid nurseries in the United States for the orchid hobbyists offering a diversity of orchid genera from five greenhouses. They also provided wholesale orchid services to the northeastern region of the US.

 In June of 2012, following the sale of the nursery, they created Salventi-Purviance Enterprises, LLC in order to continue to provide orchid consultation, lecturing and teaching, and sales of greenhouses.  Their services are available to orchid hobbyists and professionals alike.
