Doris Altúzar was born and raised in different places of Chiapas, Mexico. She studied medicine at the Universidad Autónoma de Chiapas in Tuxtla Gutiérrez. Since she was a medical student, she developed interest in working in rural communities of her state, which is why she did her year of social service with Compañeros en Salud in El Matasano, a community in the Sierra Madre of Chiapas. During that year, she realized that what she wanted to do with the rest of her life was dedicate herself to serving vulnerable populations. At the end of her year of social service in 2020, she returned as a COVID-19 response volunteer to Compañeros en Salud and then she worked providing care to patients with COVID-19 at the center for respiratory diseases that Compañeros en Salud set up in Jaltenango de la Paz. She recently began working supervising the clinical teams that provide care at the clinics of three communities where CES serves. She is excited to meet other HEAL fellows and learn more about Global Health.
