Andrew was born in Louisiana but grew up for most of his life in the Hattiesburg, Mississippi area. After looking at several different careers, Andrew decided to pursue medicine. He stayed home in Hattiesburg and studied at William Carey University for both undergraduate and medical school. After undergoing his clinical rotation time both in Hattiesburg and at the Mississippi Gulf Coast, it became apparent that he had a passion for children's healthcare. He completed his residency training in Jackson, Mississippi at the University of Mississippi Medical Center. During training, he became interested in Pediatric Nephrology due to the underserved nature of the population and the continuity working with the families. 

In his free time, Andrew can be found cheering on the LSU Tigers and exploring the outdoors. He looks forward to visiting the many parks and green spaces throughout Central Tennessee.

Layana is a Palestinian-Jordanian who grew up in Amman, Jordan. She obtained her medicine degree from the University of Jordan in 2019. Layana first came to Vanderbilt during an away rotation in medical school and is thrilled to be back in Nashville to work at Monroe Carell as a pediatric pulmonology fellow after finishing her pediatrics residency at the University of Massachusetts. As she continues to explore her career and research goals with the team at Vanderbilt, she will be working on asthma research during her second and third years of fellowship.

Outside of work, Layana enjoys hiking, snuggling with her cat, and - in true Music City fashion - she is learning the piano and polishing her ukulele skills.
