ā€œI was drawn to medicine for the opportunity to connect with people from all walks of life and offer comfort and healing when they need it most.ā€
ā€œI’m a pediatric cardiologist with University Health, dedicated to providing thoughtful, empowering care to children and their families through every stage of their heart health journey."
"What first inspired me to pursue medicine was the ability to build meaningful relationships while offering guidance and relief during difficult times."
Philosophy of Care
My approach centers on compassion and education. I believe in helping patients and parents understand the physiology and pathology behind symptoms so they feel empowered to make confident, informed choices about their health.
Favorite Parts of Medicine
  • Meeting new patients and reconnecting with longtime families
  • Collaborating with colleagues who share a deep commitment to care
Clinical Interests:
I care for babies, children, teens and young adults across the full spectrum of cardiac conditions. I have a particular interest in exercise physiology and performing cardiopulmonary exercise testing for University Health and other pediatric cardiology practices throughout the city.
Interests & Hobbies
I enjoy reading, watching movies and exploring, both internationally and discovering new corners of the Texas Hill Country.
