Katia Avelar

Patient Care Coordinator- Medical Assistant/Front Desk

Hello! My name is Katia, and I was born and raised in El Salvador until the age of ten and then immigrated to the United States. My mother taught me to be a hard worker, honest, humble, confident, and fearless. After I finished high school, she pushed me to get my MA certificate, even though I was reluctant. Through dedication and her wise words, I pushed and discovered a new part of myself. I learned how much I truly loved to help and care for my patients. Kindness is one of the traits I carry with the most pride. However, when I’m not working, I love to travel and try new foods. Change is certainly something I am open too. I’m also an outdoor fanatic and anything involving water is an obvious yes.​​​​​​​
