Kaylee Lee, MSPAS, PA-C
Kaylee Lee is a board-certified physician assistant. She has a passion for dermatology and providing the highest quality care to patients at Saguaro Dermatology in Arizona. Kaylee began her medical journey on the pre-med track at the University of Arizona, where she earned her undergraduate degree, before receiving her graduate degree in physician assistant studies from the Arizona School of Health Sciences. She is board-certified by the National Commission on Certification of Physician Assistants (NCCPA).
Before joining Saguaro Dermatology, Kaylee began her clinical career in pediatric emergency medicine, an incredibly valuable experience that provided her with a strong medical foundation. Driven by a deep interest in skin health, she transitioned into dermatology, where her clinical expertise encompasses managing a wide range of conditions, from skin cancers to rashes, with a specific focus on Herpangina and Plaque Psoriasis. She was drawn to Saguaro Dermatology because of its strong community reputation, patient-centered approach, and “family-like” feel that perfectly aligns with her own professional values.
Kaylee believes the best medical care comes from collaboration, keeping patients informed, and making treatment decisions with them, rather than for them. Her goal is to build genuine rapport, ensuring every patient feels comfortable, heard, and supported. Outside of the clinic, Kaylee loves going to concerts, catching movies, and trying new foods. Most of all, she enjoys grabbing takeout and relaxing at home with her husband, Jay, and their three dogs—especially if it involves a horror movie or a Survivor marathon.
