Louis Charles died in 1919 at 67 after being hit by a streetcar, and his wife took over the business while continuing to raise their two sons, Wilmer and Paul. It was at this time that she sought to expand the business, growing the size of the McMillan Street location and opening a second location on Walnut Street in downtown Cincinnati, followed by a third at 2704 Erie Ave. in the Hyde Park neighborhood. By 1929, the shop had locations in Norwood, Madisonville, Avondale and Pleasant Ridge as well. In order to support the volume of ice cream being produced, the business in 1937 opened an ice cream and chocolate production plant in a former printing press facility on Reading Road in Mount Auburn.
