David Sorokowsky,
Paph Paradise, CA

After receiving his degree in biochemistry from the University of Toronto, Dave opted to step outside his chosen field and operated a tropical fish import business for eight years. Upon returning to school, Dave received a degree in enology and viticulture from Brock University in St. Catharines, Ontario. While attending Brock, Dave began acquiring orchids one 2” pot at a time and before he graduated, Dave had over 100 orchids. Winemaking and a passion for orchids prompted Dave to seek a warmer climate in California about one year later. Dave has been growing paphiopedilums for about 20 years and seriously hybridizing for over 10 years. He is an accredited AOS judge and his paphiopedilums have received over 100 awards to date from the AOS and CSA. Many of those awarded plants playing important roles in his breeding program. In 2018 Dave left winemaking in order to focus all of his time running Paph Paradise Orchids.

David's topics will be "Don't Fear The Slippers" and "Compact Multiflorals for the Crowded Collection".
