Registered nurse, Siomara Segovia, sees her patients at Mary's Center's site on Flower Avenue in Silver Spring, Maryland. She received her degree from the Catholic University of Maryland and has been a member of the Mary's Center team since April 2013. Ms. Segovia speaks both Spanish and English. In her spare time, she likes to satisfy her "travel bug" through travel and enjoys activities related to the outdoors. Ms. Segovia says: "I chose Mary's Center because of the holistic approach to health. I love to work with communities and build their health and knowledge."
Begoña Cortina was born in Bilbao, Spain, and speaks English and Spanish. She is also fluent in Basque. She joined Mary’s Center in August 2016 and works as a bilingual School Based Mental Health Therapist at Cesar Chavez Prep. Ms. Cortina feels grateful to be able to work cross culturally in a diverse environment. She is a firm believer in team work and greatly appreciates the supportive environment at Mary’s Center. In addition, she feels lucky to work in a setting inspired by César Chávez, and will not hesitate to paraphrase one her favorite quotes from the civil rights activist and community organizer: “From the depth of need and despair, people can work together, can organize themselves to solve their own problems and fill their own needs with dignity and strength”.
