I grew up in Clear Lake myself, so I was very excited to become a part of this UTMB Clear Lake family. I attended the University of Houston – Main Campus for my bachelor’s degree, and I completed my medical training (medical school and my pediatric residency) in the large Texas Medical Center in Houston. In 2023, I moved back to Clear Lake so that I could give back to this wonderful community.

I have a wonderful husband, and we are lucky to have both our families and fur-siblings in the area. My hobbies include playing tennis (when it’s not too hot outside), playing the piano, and spending quality time with family and friends.

Pediatrics has been my calling since high school. I am blessed to have the opportunity to be able to educate and comfort patients and their family members in some of their most stressful times. I love that I get to watch these children grow from newborns into wonderful young adults and help them along the way.

Being a growing child (or even raising one) isn’t easy! Every patient brings their own story, challenges, and personality, and each of them has something to teach me. I just strive to be a positive light during their journeys and work to keep my patients safe, healthy, and happy.
