OAKLAND -- Lauding their "integrity, work ethic and dedication to community policing," Interim Chief of Police Sean Whent promoted 34 Oakland police officers to new ranks Friday, one of the largest such ceremonies in department history.

Among those promoted at the City Hall ceremony attended by more than 300 people were two captains, seven lieutenants and 25 sergeants. Altogether, they have more than 300 years of Oakland police service.

Some are second generation Oakland officers, some have relatives already in the department and others are from law enforcement families.

The new captains are Kirk Coleman, commander of patrol area five who has been an acting captain, and Oliver Cunningham, whose father, Noel Cunningham, is a retired Los Angeles police captain and former chief of the Los Angeles Port Police Department.

Promoted to lieutenant was Michelle Allison, wife of Oakland Capt. Darren Allison and daughter of retired Oakland Lt. Fred Mestas. The other new lieutenants are Roland Holmgren, Henderson Jordan, Nishant Joshi, whose wife is Oakland Sgt. Holly Joshi, John Lois, Erin Mausz and Sekou Millington.

The new sergeants include Robert Rosin, a homicide investigator whose father, Dave Rosin, is a retired Oakland sergeant and whose brother, Greg, is an Oakland police officer; Christina Land, whose husband Michael Land is an Oakland police officer and Steve Valle, whose brother Mike is an Oakland officer.

The other new sergeants are Brian Alaura, Sean Barre, Curtis Filbert, Sean Hall, Scott Hewitt, Casey Johnson, Kevin Kaney, Douglass Keely, John Koster, Timothy Martin, Joseph McGuinn, Michele Melham, Eric Milina, Richard Niven, Everett Peterson, Aaron Smith, Jeffrey Smoak, Kirk Staggs, Anthony Tedesco, Joseph Turner, Randy White and Rufus White III.

Whent told those being promoted that they are "the next generation of leadership" in the department, who must be "intensely dedicated to organizational excellence, innovative crime fighting and community collaborations. As leaders your primary task is no longer solely focused on performing at a high level, but on inspiring the best performance by others."

Singling out the sergeants, Whent told them they were in "the most integral leadership position in the department," shifting from "being a doer of police work to a supervisor of police work. It is incumbent on you to ensure that officers are doing police work that is constitutional, fair and safe."

Five civilian employees were also promoted. They are Debra Galaviz-Flores to latent print examiner III, Veronica Jones to records supervisor, Susan Molloy to criminalist II, Nancy Parlette to police communications supervisor and Dunnie Tong to administrative analyst II.
