Who is the pastor on the right?

I found two confirmation class photos that both say 1977. It is unclear what the exact year is but appears to be a year or so earlier.

• Rev. Frank Nickel (left, 1976-1993)
• Rev. Larry Leister (?)(right, 1972-1975)
• Rev. Paul Shumate (?)(right, 1975-1977)

Bounds intersection appears to be 1976.
