Todd Renshaw, the city of Frisco director of public safety, will retire after 20 years of service with the city and 31 years of experience in law enforcement and public safety.

His retirement is effective May 31.

Renshaw served as chief of police from 1994–2012. In October 2012, he was promoted to director of public safety, charged with overseeing the police and fire departments as well as emergency management.

"Probably the most gratifying aspect, of staying in a single location for the bulk of one's career, is seeing people begin as 'students' who later evolve into 'teachers'," Renshaw said. "It's been a pleasure to see those people grow and progress in this [public safety] profession."

During his tenure, Renshaw saw the Frisco population grow from about 11,000 people to more than 100,000 people. The police force grew from 20 officers to more than 150 officers.

Renshaw's law enforcement career began in 1983 in Allen. He left Allen for an appointment as captain of police in Coppell.

Attributed to Renshaw's efforts are community programs including the Citizens Police Academy, Citizens on Patrol and National Night Out.
