KarriAnn’s always insatiable interest in dermatology and science only grew when she started her internship with Ava MD in 2008 while finishing up her studies. A member of Sigma Theta Tau, the International Honor Society of Nursing, she became a permanent part of the AVA MD team in 2010. In 2016, KarriAnn and Christine Nell formed their company, Skin Sisters, teaming up with Dr. Shamban to launch SkinFive. So she couldn’t be happier to deliver the most transformative skin services to patients at AVA MD and SkinFive.
