Tijdens haar verblijf in Europa organiseerde en dirigeerde zij een serie concerten voor de "United States Information Agency".
Na haar terugkomst in de Verenigde Staten in 1959 doceerde zij een aantal jaren aan het Florida A & M College in Tallahassee en aan de Atlanta Universiteit. In 1971 werd zij ziek met paralytische apoplexie en moest verschillende jaren in het ziekenhuis blijven. In deze tijd leerde zij (autodidactisch) met de linkerhand te schrijven en kon ook weer componeren.
Als componiste schreef zij werken voor verschillende genres zoals werken voor orkest (12 symfonieën), concerten voor instrumenten en orkest, harmonieorkest, kerkmuziek, vier opera's, cantates, koor- en kamermuziek. Haar stijl is vooral neoklassiek.
