The Shastid list was founded in 1997 by Jack Shastid, a prominent Bullmastiff breeder and judge.
The object was and remains to provide a place where people could congregate and talk about Bullmastiffs.
Following his death in November, 2001 ownership passed to his wife, Gerry Shastid. Currently the list is owned by Mark Essary.
Scott Peterson started helping administrate the list in 1999 and has been the day-to-day manager since Jacks death.
Administrative help is also provided by Tamara Cady.
