The Voice of Prophecy, founded by H.M.S. Richards, Sr., is a Seventh-day Adventist religious radio ministry headquartered in Loveland, Colorado. Initially airing in 1929 on a single radio station in Los Angeles the Voice of Prophecy has since grown to numerous stations throughout the United States and Canada. It was one of the first religious programs in the United States to broadcast nationally. Under the leadership of Shawn and Jean Boonstra, the ministry has now expanded into additional forms of media, including the weekly Disclosure broadcast.
