After the Monday 5 p.m. filing deadline, the Longmont City Council election field has now expanded to eight candidates, with three of the four open seats contested.

Sarah Levison, whose at-large council seat is up for grabs as she reaches the end of her eight-year term limit, is competing with incumbent Mayor Dennis Coombs and former councilman Ron Gallegos.

Levison was elected to council in 2007 and re-elected in 2011. Levison could not be reached for comment about her mayoral run.

Coombs is co-owner of the Pumphouse Brewery, 540 Main St., and worked 31 years as an electrical engineer in the aerospace industry. Gallegos is a financial consultant and artist who also owns the Conejos Fine Art Gallery. He was a Ward 3 councilman from 1995 to 1999 and also ran unsuccessfully for at-large council seats in 2011 and 2013.

Gallegos said he entered the race Monday because he believes there should be some competition for the Mayor’s seat.

“Some people are addicted to golf and some people are addicted to petunias and gardening and I’m addicted to improving the community and whatnot,” Gallegos said about his fourth council run.

To file for candidacy, each prospective mayor had to provide 50 signatures by registered Longmont voters by 5 p.m. Monday. Longmont City Clerk Valeria Skitt said her office was able to verify the address of 49 voters on Gallegos’ petition and would contact Boulder County Tuesday to verify some of the remaining addresses, which may have slight variations.

As Levison runs for mayor, two candidates are vying for her at-large seat. Scott Dunn is a partner with the Flanders, Elsberg, Herber & Dunn LLC law firm and has been on the city’s planning and zoning commission for the last 10 years, chairing it for the last three.

Dunn’s competition is Joan Peck, who organized and co-led a successful petition effort in 2012 to get a city-wide hydraulic fracking ban on that year’s ballot. This year, Peck teamed up with former City Councilwoman Karen Benker to found Citizens for Finishing FasTracks.

Paul Rennix had previously filed for the at-large seat up for grabs, but switched his candidacy to the previously uncontested Ward 3 seat Monday.

Rennix, who works for Twitter in Boulder and has organized Americana concerts and potlucks along the Front Range, said he was on the fence between the two seats but switched to avoid a three-way race. Instead he will run against incumbent Councilwoman Bonnie Finley for the seat.

Finley works as manager of member involvement at the Colorado Association of Commerce and Industry and has previously worked as a mortgage loan officer.

Brian Bagley, the council’s mayor pro tem, is running unopposed for re-election for his Ward 1 seat. Bagley founded the Bagley Law Firm and has taught as a senior lecturer at the University of Colorado’s Leeds School of Business.
