Mayor Steve Bach’s first year was marked by significant turnover at City Hall.

Who’s out?

Patricia Kelly: Retired in September. The former longtime city attorney announced her retirement just weeks after Bach expressed surprise and disappointment about a series of ballot proposals drafted by Kelly that would have stripped some of the mayor’s powers.

Terri Velasquez: Fired in July. The former chief finance officer said the firing came after she reported financial wrongdoings, sparking a months-long investigation that found her allegations to be without merit. Velasquez still has a $1 million claim pending against the city.

Richard Myers: Forced out in October, though the city called the former police chief’s departure a retirement. Myers left after a year of bad press for the department that included the arrest of two officers, including one accused of molesting children, and a botched liquor investigation at Hooters.

Lisa Bigelow: Fired in March, though the city also called her departure a retirement. The former budget manager was let go after she leaked a series of private emails written by the mayor.

Kathryn Young: Retired in July. The former longtime city clerk left on good terms. But she faced criticism during the mayor’s race after creating confusion over the legality of corporate contributions and other campaign reporting requirements.

Sue Skiffington-Blumberg: Resigned at the mayor’s request in May. The former manager of public communications was shown the door after she disclosed that she acted on orders to portray the city’s budget situation as dire following the defeat of a proposed property tax increase.

Nancy Johnson: Resigned unexpectedly in February. Johnson, a former assistant city manager who had been elevated to deputy chief of staff and parks director, was among only a handful of high-level city employees that Bach had kept in his administration.Who’s in?

Laura Neumann: Chief of Staff/Chief Administrative Officer. Before joining the city in January, Neumann was vice president and general manager of Cheyenne Mountain Resort.

Chris Melcher: City Attorney. Melcher left Colorado College, where he been chief legal officer since 2006, when he was tapped to replace Patricia Kelly in September.

Steve Cox: Chief of Economic Vitality and Innovation. The former fire chief and interim city manager was interim chief of staff for the first half of Bach’s first year in office.

Pete Carey: Police Chief. Carey was named interim police chief in October and then given the job on a permanent basis in January. Carey started his law enforcement career with the El Paso County Sheriff’s Office in 1982 and joined the police force in 1984.

Rich Brown: Fire Chief. Brown was appointed fire chief in January after serving in the job on an interim basis since June. Brown joined the Fire Department in 1980.

Kara Skinner: Chief Financial Officer. Skinner, who joined the city in 2006 as a principal analyst, had been interim budget director since February. Bach announced her promotion to CFO on Thursday.

Karen Palus: Director of Parks, Recreation and Cultural Services. Palus, who served most recently as parks and recreation director for the city of Tampa, Fla., will start her new job June 18.

Helen Migchelbrink: Public Works Director/City Engineer. Migchelbrink left her job as city engineer in Fort Collins to work for Bach in May.

Cindy Aubrey: Chief Communications Officer. Aubrey is a former local television news director who went to work for Bach in July.
