  • She enjoys being outdoors by the water and taking in hill country views, and her favorite place in Austin is Mozart’s Coffee.
  • She loves desserts and can’t live without her KitchenAid, which she regularly uses to make cupcakes and cakes.
  • When not in surgery, she and her husband love hanging out on beaches and seeking out foods from other cultures. Her favorite place they've traveled to is Koh Chang Island because of the beautiful beaches and brightly flavored food.
  • Because of her cautious and soft-spoken nature, many are surprised to learn that she has been skydiving and gets really into video games like Guitar Hero.
  • When you meet her at the office, take a peek at her socks! They’ll likely be mismatched.
  • Why Mohs Surgery? She was drawn to dermatology because she knows things on the skin can affect both self-image and quality of life. She became a Mohs surgeon because she enjoys the delicate nature of the process and paying attention to tiny details. With Mohs surgery, she can also see for herself through a microscope that skin cancer is gone, and she finds it rewarding to provide the treatment with the highest cure rate for most skin cancers.
