Dennis was born on November 12, 1943 in Crookston to Frank and Stella (Perreault) Kaiser. He was the youngest of seven children. He attended Crookston Cathedral School. Dennis and his former spouse, Joyce (Amiot) Heidmann, were blessed with two sons, Greg and Brent.

Rocky enjoyed traveling, spending significant time in California, Colorado, Texas and Florida. He enjoyed working on cars, deer hunting, fishing, and conversations with anyone he met while sharing a coffee or beer.
