Republicans Jack Fortner and Keith Johns easily won their November elections and now represent commission districts 4 and 5, respectively, which encompass Farmington.
Fortner replaced his successor, James Henderson, in District 4.
Fortner previously represented the district from 1996 to 2004. Henderson, who was president of San Juan College for 27 years, was the commissioner from 2004 to 2012.
County commissioners have a two-term, eight-year limit but they can run again four years after leaving office.
In addition to being elected commissioner three times, Fortner is a Farmington attorney and president of the University of New Mexico Board of Regents.
He has said he will use the positions he holds in New Mexico to try to diversify the local economy as a commissioner.

In addition to the commissioners, County Clerk Debbie Holmes and her chief deputy Tanya Shelby, and County Treasurer Mark Duncan and his chief deputy Carol Taulbee were also sworn in.
About 75 people -- friends, family, county employees and community members -- attended the ceremony. Farmington Municipal Judge Bill Liese swore in the officials.
