Krista Smith, PA-C

A certified physician assistant with lots of dermatology experience, Krista Smith joined us from Huntington Medical Center. Under the direction of our dermatologists, Krista conducts examinations and treats common skin diseases. Plus, she can handle injections, biopsies, excisions, and suturing as needed. She is well-versed in popular cosmetic procedures including intense pulsed light (IPL), Botox®, Restylane®, and Juvéderm®.

Krista and her husband are raising two energetic boys and she is a volunteer teacher in the children’s ministry at their church. The family enjoys hikes in the San Gabriel Mountains. Being outdoors is a way of life for Krista. As a child, she was a competitive gymnast until she literally outgrew the sport. “At 5.9, I realized it was time to find a new sport, so I took up field hockey. I also love snowboarding and water skiing,” she says. “My all-time favorite vacation is going to Lake Powell on a houseboat.”

Of course, she always wears sunscreen!

Krista Smith, PA-C is in our office on Mondays, Wednesdays, and Fridays.
