Visit Knoxville is pleased to welcome Randy Tyree to the Sunsphere team. Tyree is an East Tennessee native who served as Mayor of Knoxville during the 1982 World’s Fair. From May through October of that year, the Fair welcomed more than 11 million visitors from around the world. Visit Knoxville is thrilled to have Mayor Tyree at the Sunsphere to welcome visitors once again.
Over the course of 10 years, Tyree worked in law enforcement, including service with the Federal Bureau of Investigation as well as the Knoxville Police Department – also holding the title of Police Commissioner in the City of Knoxville.
Tyree was elected Mayor of Knoxville in 1975 at age 34. He was the city’s youngest candidate ever to hold that office and won re-election to a second four-year term to lead planning and preside over the city during the World’s Fair. The Performance Lawn at World’s Fair Park was named in his honor in September 2019.
You will find Mayor Tyree at the Sunsphere Tuesdays – Fridays from 10am-1:30pm. Make plans to visit with him now.
