About Me

I grew up in Chattanooga, Tenn., but spent each year looking forward to our family vacations on the First Coast. My husband and I enjoy cooking, outdoor activities, and college football. Our daughter is my No. 1 seashell-collecting and sandcastle construction partner. We have two black labs, Tux and Berkeley, and they are the true superstars of our family.

Breast disease, both benign and malignant, can be very anxiety-provoking for patients and those closest to them. And a breast cancer diagnosis can seem to turn the world upside down. For women, it is important to me to not only ensure the highest level of cancer care, but also to remain mindful of aesthetics and maintaining your femininity. It is my mission to partner with my patients to help them feel informed to make the best care decisions for them, and to make the journey easier and more transparent.
