Received Doctor of Veterinary Medicine from St. George’s University in 2022. Clinical rotations were completed at the University of Illinois Urbana-Champaign. Special interest in animal behavior. Fear-free certified and committed to continuing education regarding the latest advancements in animal behavior. I enjoy meeting new people every day, and helping them and their pets live their healthiest, happiest lives together.

Before vet school I was a nursing assistant, and a vet tech for several years before deciding to pursue my Doctor of Veterinary Medicine. During my time in vet school, I had the opportunity to volunteer doing sea turtle conservation work in Grenada, specifically with Leatherback turtles!
I was born and raised in the Southwest Chicago suburbs, wanting to be a pediatrician! I always wanted to help the helpless, and I’m very grateful I got to combine that passion with my love for animals as a veterinarian. I currently live near Tinley Park with my husband, stepdaughter, 2 chihuahuas, 2 ferrets and a leopard gecko. I enjoy all things outdoors in my free time such as hiking, camping, and swimming.
