Carlisle was hired as Chief of the Vienna Police Department in February 2001. He joined the Fairfax County Police Department in 1978 and held several positions throughout his tenure, retiring in 1999 as Commander of the Criminal Investigations Bureau. Prior to his appointment with the Town of Vienna, Carlisle served as Assistant Chief with the Falls Church Police Department from 1999 to 2001.
â€œIt has been an honor and privilege to serve in this position and something that I remain thankful for every day,” Carlisle said in a letter to the town manage.”I came here to a department that was under difficult circumstances and the initial challenges were many, but from challenges we created opportunities and we have made the most of every one of them. In almost every way, this department bears little resemblance to that which I took over; a credit to every employee who works here.â€
