Jonathan E. Sisk,

Jonathan is an author, trainer, editor, publisher, speaker and consultant specializing in the Pick-Nelson data model, now commercially known as D3, whose on-line help and documentation is still based upon his work. 

Jon pioneered the Pick training and documentation industry in the early 1980's, with classes nationwide and in over a dozen countries. JES Affiliates and Associates comprised an incomparable roster of talent who brought industry experience and communication skills to countless students.

JES still teaches aspiring D3 technicians remotely. This allows for a personalized experience, using the client's actual data and code, addressing their specific needs, in a fraction of the time it used to take in a classroom. We started doing this long before it became the Pandemic standard.
