He settled in New Albany, Indiana, where he had a studio on East Market Street and was a member of the Wonderland Way Art Club. In 1915, he had a studio on Third Street in Louisville. Krementz was a contemporary of Carl Brenner and Harvey Joiner. He, like Brenner, participated in the vibrant cultural life of the German immigrant community in the Louisville area.
