Jerry Vlasak (born c. 1958) is an American animal rights activist and former trauma surgeon. He is a press officer for the North American Animal Liberation Press Office, a former director of the Animal Defense League of Los Angeles, and an advisor to SPEAK, the Voice for the Animals.
Vlasak came to public attention in 2003, and 2004 and again in 2008, when he made statements that appeared to justify the use of violence against animal researchers. He responded that he had been quoted out of context and strongly denied having said anything to encourage violent action. Nevertheless, as a result of his statements, he and his wife were banned from entering the United Kingdom in 2004, on the grounds that their presence, according to the Home Secretary, "would not be conducive to the public good."
Born in Austin, Texas, Vlasak graduated with an M.D. from the University of Texas Medical School at Houston in 1983. He is board certified in General Surgery and is licensed as a medical doctor in California.
He was an animal researcher himself, and saw no problem with it at the time. According to the Los Angeles Times, he conducted research on dogs' arteries in a laboratory at the Harbor-UCLA Medical Center, during or after which the dogs were killed.
As of September 2013, Vlasak is affiliated with the Riverside Community Hospital in Riverside, California and St. Francis Medical Center in Lynwood, California.
