From 1930-1932 Eustis was a member of the Philadelphia Grand Opera Company, where she portrayed such roles as Maddalena in Rigoletto, Margret in Wozzeck, Marthe in Faust, the Witch in Hänsel und Gretel, and Floßhilde and Grimgerde in The Ring Cycle among others. She was also a regular soloist with the Philadelphia Orchestra during the 1930s in concerts of operatic works and in works from the standard concert repertoire, a collaboration which resulted in several recordings. She also notably portrayed 'Amelia's friend' in the world premiere of Gian Carlo Menotti's Amelia Goes to the Ball on 1 April 1937 at the Philadelphia Academy of Music.[citation needed]
