(written from a Production point of view)
John Dodge Vancitters (born 23 October 1964; age 55), going through life by the name "John Van Citters", was the developer of the Starfleet Operations Manual supplement to the Star Trek Roleplaying Game, which was published in 2003 by Decipher in conjunction with Paramount Pictures Product Development, his first recorded involvement with the Star Trek franchise.
Van Citters became from 2006 onward Vice President, Product Development at CBS Consumer Products, managing licensed publications, which included the plethora of Star Trek merchandise, and frequently seen promoting these at Comic-cons and Star Trek conventions, causing him to become de facto recognized as the official face of the Star Trek franchise. Perceived by many Star Trek affiliated staffers as a very Star Trek friendly studio executive, Van Citters has been frequently acknowledged by authors in licensed reference books, such as the 2010 USS Enterprise Owners' Workshop Manual (p. 160). He is particularly valued by Ben Robinson, project manager of the British Star Trek: The Official Starships Collection and Star Trek: Discovery The Official Starships Collection, for his unwavering support for his partwork publications.  As if to underscore the Star Trek friendly reputation he has gained, it was Van Citters who became the driving force behind the decision to commission an updated fourth edition print version of the Star Trek Encyclopedia, released in 2016 as part of Star Trek's 50th anniversary, pleasantly surprising fans and authors alike, who never expected to see an updated Encyclopedia print version again in the digital age.
