Glaser graduated from Yale University Divinity School with a M.Div. degree in 1977. While still a student there in 1974, he formed a support group for gay Christians. In 1976, during an intern at University of Pennsylvania, he founded a peer counseling service for gay and lesbian people.

From 1976-77, he served as the only openly gay man on the Presbyterian Task Force to Study Homosexuality, and the rejection of its gay tolerant conclusions by the Church meant that Glaser himself was refused ordination as clergy by the Presbyterian Church (USA) in 1978.

After leaving Yale without his ordination, he created and served (from 1978-1987) as Director of Lazarus Project, a ministry of reconciliation between the church and the lesbian and gay community in Los Angeles, funded by the Presbyterian Church . He also worked with as a national coordinator and editor for Presbyterians for Lesbian and Gay Concerns (now known as More Light Presbyterians) and their newsletter, More Light Update.

He began serving MCC San Francisco as Interim Pastor on November 1, 2006, having been ordained by this denomination. He has also served as Interim Pastor of Christ Covenant MCC in Decatur, Georgia.

He began serving as Interim Pastor at Virginia-Highland Church in Atlanta, GA, on January 1, 2009, and is leading that church to define its vision for ministry in the Virginia-Highland neighborhood of Atlanta. [1]
