Dr. Katherine Ferris completed her undergraduate training at the University of Southern California, after growing up in Dallas and later Arizona. After earning her BA degree in Psychology (with a Spanish minor), Dr. Ferris took time off after her undergraduate training to pursue professional dance in ballet, jazz, hip hop, and aerial arts, during which she performed with various Los Angeles companies as well as well-known artists such as Britney Spears and Will Smith. Her athleticism promoted an appreciation for human physiology, providing a foundation to manifest her profound interest in medicine. Once destined for this profession, she quickly realized her passion for all things skin care. She entered medical school at University of Miami in Miami, FL, where her love for dermatology flourished, even prompting a one year hiatus dedicated to dermatologic research; during this training, she became involved in dermatology interest groups and several dermatologic medical societies. She then completed her internal medicine internship at St. Mary Medical Center of Long Beach, followed by dermatology residency at UC Irvine. There, she served as head coordinator of Lestonnac free medical clinic for two years, as well as director of resident cosmetic training and chief resident for Quality Improvement. Dr. Ferris has interest in broad categories within dermatology: general dermatology including acne, rosacea, pigmentation issues, psoriasis, eczema, contact dermatitis; skin cancer surgery; and cosmetic procedures such as botox and fillers. She has published numerous articles, book chapters, and given many presentations on diverse topics in dermatology. She continues to lead an active lifestyle, enjoying running, hiking, dance, yoga, surfing, traveling, but otherwise enjoys a simple life with her boyfriend and dog, enjoying cooking and spending time with loved ones.
