I'm excited to have the privilege of working with Dr. Arif Usmani at Benchmark Diagnostics. I attended Oregon Health and Science University for medical school and did my dermatology residency in Milwaukee, Wisconsin.  I subsequently moved to Dallas, Texas, to do a fellowship in Dermatopathology at The University of Texas Southwestern.  Since the fellowship, I've been able to combine working in both clinical dermatology and dermatopathology. I enjoy and am challenged by getting to experience both direct patient care and getting to the underlying cause from the pathology sample.  

I have a deep understanding of skin conditions and a passion for finding the underlying cause of skin disorders.  I believe in a collaborative approach to patient care and individualizing a care plan for each patient.  

My two daughters keep me happily busy when I'm not at work. I enjoy hiking, playing soccer, and reading in my spare time.
