The actor, who was previously married to Christina Applegate, proposed to Kramer during a Christmas (09) vacation in his hometown of Edgewood, Maryland.
And they finally exchanged vows on Sunday (04Jul10) in Glen Arbor, Michigan in front of their close friends and family.
A representative for Schaech tells America's OK! magazine, "Jana and Johnathon were married in an intimate outdoor ceremony in Glen Arbor to the witness of 100 close friends and family.
"(Kramer wore) a custom-made Jim Hjelm wedding gown. (Her) bridesmaids wore Jim Hjelm, as well."
Schaech and Applegate divorced in 2007.
