Originally from Bethesda, Maryland, Jenny began her violin studies with her father, Hendrik Essers. She attended the University of Michigan at Ann Arbor, a student of Angel Reyes, and worked part time with the Toledo, Ohio Symphony until graduation.
Two seasons with the Oregon Symphony in Portland, Oregon preceded Jenny's arrival in Vancouver in 1975 as a member of the first violin section of the VSO. She also played two seasons in the viola section of the CBC Radio Orchestra under John Elliot Gardiner, and was inspired to pursue further studies of early music and period instruments. She then attended workshops with Monica Hugget, David Douglas, and Marc Destrube, and played violin and viola with the Pacific Baroque Orchestra for twenty years.
In recent years Jenny has also played chamber music for Early Music Vancouver, the Hycroft Concert Series, the Silk Purse, and Roedde House, frequently as a member of the piano trio, Trio Amalie.
Jenny lives with her husband, John Rubin, and has two grown children.
