She worked as a movie theater cashier, making 57 cents an hour, and taught classes at the university, teaching up to twelve credits a semester. At the age of 24, three years after she enrolled, Henney graduated from the University of Miami with a Bachelor of Science degree with a major in physics and a minor in mathematics and chemistry, as well as a Master of Science degree in pure mathematics. It was during her freshman year at the University of Miami, Henney met her future husband, Alan G. Henney, in a nuclear physics class.

The latter made her responsible for coordinating the hiring and managing of off-campus professors and teaching assistants, as well as making her a liaison with the university's numerous international students. It was during this time that Henney wrote her dissertation "The theory of set-valued additive functions defined on base-cones in Banach spaces with values in the collection of compact, convex sets".
