Everything About Orchids
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.

Lectures and Workshops
Tom Purviance and John Salventi have been in demand as speakers and workshop leaders throughout their orchid careers. One of our most notable recommendations comes from the Coordinator of Continuing Education at Longwood Gardens.
"John Salventi and Tom Purviance have been teaching at Longwood Gardens since 2002. After more than 34 workshops we continue to receive glowing comments from our students. The comments speak for themselves?" John McClintock, Director of Continuing Education
"Orchids for Beginners met all my expectations. The instructors were very well prepared to cover topics that beginning orchid growers want to know, and they explained everything clearly and with wit. With 25 years of experience, owning orchids and a nursery, they were the ideal instructors. You can't beat examples of orchids, which they had brought and the re-potting demonstration was perfect. I have been checking books and the internet, but what will stay in my mind is seeing someone re-pot an orchid and his anticipating our questions with regard to that, as well. To me, there is nothing I would change about the class. Having the handouts already prepared and in an envelope was first class."
"The Orchid Re-potting Course was my first with Longwood, but will certainly not be my last. The course was a perfect combination of informative lecture, demonstration, then hands on do it yourself. The course leasders were highly competant, experienced professionals who generously sheared their knowledge, with a good sense of humor. I loved the class and learned a wealth of information. I would highly recommend this class and will take other classes also.
