Della was born in Neapoli, Kozani and grew up in Veria, Northern Greece (near the birthplace of Alexander the Great). It was in high school that she developed her passion and talent for painting. After school, Della lived in Toulouse, France, where she studied French literature and philosophy. As a young woman, she also worked as a model in Johannesburg, in New York and Athens.
After her marriage to Herbert Rounick in New York, Della lived in the condominium of the museum of modern art for twenty years, and it was her frequent visits to the museum, that inspired her to take painting courses at the Art Students League, under the teaching of Bruce Dorfman, and the famous artist Richard Pousette Dart from 1989 to 1992.
The sudden death of her husband in 1993, put Della’s painting career on hold. She became the CEO and a chairman of his fashion company, the HE-RO Group (which was publicly listed in the NY stock exchange) for four years. While she was deeply involved in the designing of various lines (Pret-A-Porter of Black Tie by Oleg Cassini, Oscar De La Renta, Bill Blass, Fabrice), she also created her own line “Niteline” by Della Roufogali. In the winter of 1993 and 1994 Della took Faux Finishes lessons, at the Isabel O’ Neil Foundation in Palm Beach. In parallel, she worked at her own studio in Palm Beach, developing her painting series “The Hermafrodites”. In 1997 Della donated all her paintings to AMFAR for an art exhibition at the New World Art Center in Soho, New York.
In 2004 Della moved to Athens, Greece, where she still lives, and spents the summer months in Mykonos where she has started sculpting many of the themes present in her early paintings. At the same time Della continues to take sculpture classes at her school, the Art Students League.
Her first series Andromeda and Pleiades are cast in bronze, black and white colors, and occasionally in vivid colors as red, deep blue, light blue and dark brown. Della had her first exhibition this August in Mykonos, which was very well received, most notably from the reapected critic Iris Kritikou who gave the exhibition an outstanding review.
