The new year has brought several changes to the command staff of the Montgomery County Sheriff’s Office, including a new chief deputy.

Rob Streck, formerly a captain, was elevated to chief deputy on Jan. 1. The prior chief deputy, Scott Landis, will be the major in charge of the county jail.

Sheriff Phil Plummer said that he still had complete confidence in Landis, who is “still on the leadership team.” The change was part of an overall effort to move people around so that new ideas emerge and the office continues “building a well-rounded command staff,” he said.

Other changes effective Tuesday include:

— Maj. Daryl Wilson, who has been in charge of the jail, will take over operations.

— Maj. Dave Hale, who had been over operations, will take over personnel.

— Capt. Jeremy Roy, who had been in the jail, will run the office’s Harrison Twp. substation.

— Capt. Jeff Papanek, who had been in Harrison Twp., will run the Washington Twp. substation.

In addition, there were two promotions, as both Matt Haines and Tom Flanders were promoted from the rank of sergeant to captain. Flanders will be in the jail and Haines will run the Regional Dispatch Center.

Two of the position changes were due the retirements of captains Dee Osterfeld and Glen McIntosh, Plummer said.

Streck, who had been running the dispatch center, is a “good technical guy,” which will be important as the office develops new ways to use technology to fight crime, Plummer said.

Wilson had been over the jail for a long time and Plummer wanted him in operations. But because of the the unique challenges of the jail, Plummer wanted an experienced hand in charge there so he selected Landis, he said.

“I have confidence he can run the jail,” Plummer said. “The jail is tough.”
