Desiring to see a change, a diverse group of Kansas City professionals joined together to bring theatre back into their community through a new non-profit organization – Summit Theatre Group. In 2018, STG recognized the need in our community for more educational art opportunities and STG Studio was born. After almost 20 years, STG continues to proudly serve our community.. 180 NW Oldham Parkway Lee’s Summit, MO 64081 816.272.5451 Visit Website Get Directions Print PreviousLee's Summit Symphony Next Music in the Park
