I graduated with my bachelor degree in animal science with a minor in business from Texas Tech University in 2013. I went to Texas A&M for vet school and graduated in 2017. After graduation I completed a year long rotating internship at Nashville Veterinary Specialist in Nashville TN. After then internship, I practiced for 1 year at a general practice in Nashville before moving back to work here in July 2019. My interests are in neurology, but I love all aspects of veterinary medicine. This is why I did not choose to specialize after my internship.
I was born while my parents were still in vet school so it was only destined that I follow in their footstep. Now I am literally getting follow in their footsteps everyday. I have basically grown up in this clinic and now getting to be associate and working along side them is amazing. I currently live in Frisco and have one dog who is a black lab/pit mix named Bentley. I pretty enjoy all outdoor activities but really enjoy playing golf any chance I get. My dad and I are just a little competitive against each other.
