Andres Hidalgo.jpg

Andres Hidalgo

Officer

Andres Hidalgo was born in Guayaquil, Ecuador and raised in Miami, Florida. On April 14, 2012, his life changed forever when he was diagnosed with acute lymphoblastic leukemia (ALL) at the age of 15. High school classes and extracurricular activities were replaced by doctors’ visits and chemotherapy sessions. He was suddenly immersed in the world of medicine and his doctors and nurses quickly became his role models. After much support from family, friends, and the community, he overcame his diagnosis and decided to be a patient advocate for children suffering from pediatric cancer by sharing his story. As a survivor speaker, Andres has helped Sofia’s Hope raise money and awareness for pediatric cancer since 2016.

 

After graduating from Belen Jesuit, Andres attended the University of Miami to pursue what he thought would be a career in medicine. He quickly realized his strengths lied in reading, writing, and public speaking. He decided that pursuing a career in law would allow him to showcase these skills. Andres is currently fourth year JD/MBA candidate at UM. Upon graduation, he is interested in pursuing a career in litigation. His dream is to be able to advocate on behalf of those who have suffered tremendous losses or tragedies. 

 

“No one could have prepared me for the physical and emotional toll my diagnosis and treatments would have on me and my family. Volunteering for Sofia’s Hope helped me connect with others who have experienced similar struggles. I am proud to work for a local organization that focuses on the specific needs of families in our South Florida community.”
