(1937-2025)
When the three Adrian Dominican Sisters who founded the Colegio Santo Domingo – Sisters Mary Philip Ryan, Thomas Ann (Eileen) Burke, and Rudolf (Dorothea) Beuttenmuller – arrived in the Dominican Republic in September 1945 to begin the process, one of the first people they met there was Humberto Ruíz Castillo, the architect/builder selected for the project.
Among the four boys and three girls born to Humberto and his wife, Ana (Berges) Castillo, were two girls who would soon become Colegio students and would go on to join the Congregation: Teresita, known as TeTe, and Margarita, called Margot, the youngest of the seven. Their siblings were Fernando, Humberto, Hugo, Felix, and Pura.
Margot was born in Santo Domingo on March 6, 1937. Her earliest schooling came at the Franciscan Colegio Serafin Asis, which she attended through fourth grade. When the Colegio Santo Domingo opened in 1946, she transferred and was a student there until her junior year of high school.
Right from the start of the Adrian Dominican presence in Santo Domingo, the Sisters and the Ruízes had a very close relationship. “I became very fond of the Sisters, who were joyous, prayerful, intelligent, and friendly,” Sister Margot wrote in her autobiography. “When I decided to enter religious life, there was but one choice: the Adrian Dominicans. When I told Sister Mary Philip of my interest in religious life, she immediately helped me to make arrangements to go to Adrian. I think she was afraid some other congregation would get me.”
