Mitch comes from a traditional Jewish family in New York City. He attended Orthodox Hebrew school and was bar mitzvah at age 13. In his first year of college, Mitch hitchhiked across the country to California, where he met some Christians who told him Jesus was the Jewish Messiah. Mitch accepted Jesus in November of 1970, attended Bible school and seminary, and has been serving in Jewish missions since then.
Almost immediately after becoming a believer, Dr. Glaser became involved with what was then known as the West Coast branch of Chosen People Ministries (formerly known as the American Board of Missions to the Jews). This was the beginning of a forty-year ministry that has included working with Jews for Jesus and Ariel Ministries. Since 1997, Dr. Glaser has served as president of Chosen People Ministries—one of the oldest and largest Messianic missions in the United States.
