I don't come up with anything really. I do see 2 "Nyberg's" in Fortuna, Ca.
1. Phil Nyberg....a lot of 4H and animal competition in Newspapers.
Later works in Animal Medical Center

2. Laurie Nyberg...listed as a secretary

Might take a look in Montana/Colorado......Montana and Colorado came up in some of the searches.

SORRY ☹️
