Pediatrician
OSF HealthCare St. Joseph Medical Center

Dr. Samina S. Yousuf always knew she wanted to be a doctor, and a pediatrician in particular. The cliché of “helping people” really is her passion. She believes when you work in pediatrics, you are not only affecting the life of your patient, but their whole family. That potential to improve the lives of families is what pulled her into this inspiring profession.

She is grateful to work at OSF Medical Group with an accomplished group of providers, nurses and staff. It’s evident the well-being of the patients they serve is the top priority for every member of the team.

Having lived on three continents, and in large metropolitan cities like London – where she was born – Chicago and Boston, Dr. Yousuf never imagined she would settle among cornfields. She finds many attributes that make it easy to live here – safety, excellent schools, good basic moral values of caring for your neighbor and welcoming diversity.

Dr. Yousuf is married to a neuroradiologist. They have two sons. As a family, they love traveling and exploring cultures within the U.S. and abroad. She loves learning new languages and speaks fluent Urdu, snippets of Spanish and bits of French.

Her oldest son has special needs, and through him she has a very deep connection to the special needs community, especially to children with autism. Her son has taught her so much, but most importantly, to value every single day, to savor the little joys and treat those who are in need with the utmost respect.
