[4] On November 7, 1935 Pomeranz married Edward N. Allen (1891–1972), who was to take over as president of the family Sage-Allen department store in 1941 after his mother's death.

Mildred played and taught piano as a young woman; she was a student of R. Augustus Lawson, an African-American concert pianist who became a dean at the Hartt College of Music.

Mildred Allen's husband Edward was the mayor of Hartford from 1947 to 1948 and served as Lieutenant Governor of Connecticut from 1951 to 1955.

Mildred, who had been active in civic organizations and Republican women's groups, ran for Secretary of State in 1954 and won by 14,309 votes—the largest margin of any state-level official in that year.

[8] Allen received a distinguished citizen award from the Order Sons of Italy in America in 1958[9] and an honorary doctorate of laws from the University of Hartford in 1960.
