Capt. Tim Wallis was named the only finalist for the chief position, which will be officially vacated by Chief Randy Johnson on March 16. Wallis has been a law enforcement officer for nearly 30 years, and a member of the Lawrenceville force for more than 20.

“I am grateful for this leadership opportunity,” said Wallis in a city release. “This department is filled with strong, respectable men and women who put their lives on the line every day and I am humbled to have the privilege of leading them and serving them in that right. I look forward to working closely with the city to support its vision for growth while working to keep our residents and visitors safe and protected in the process.”

Wallis will begin serving as chief on March 16.
