Argentina Leon, M.D. was born and raised in Latin America. Her hometown is Miami, Florida. She obtained her undergraduate and medical school degree at the University of Miami, Miller School of Medicine. It is no surprise that she completed her Dermatology residency at the University of Miami/Jackson Memorial Hospital. Dr. Leon is also trained in Family Medicine at Brown University/ Memorial Hospital of Rhode Island. With her unique background, her goal is to bridge the gap between dermatology and medicine. To her, skin disease is not “just a skin thing” but has an important aspect of a person’s general health with implications for other major organ systems. Her area of interests includes dermatologic surgery, psoriasis/eczema, phototherapy, cosmetics, and clinical research trials.

She is most grateful for her mentors who have given her endless support and made a phenomenal impact in her career and life in general. She believes life is about making the most positive impact in other people’s lives. She speaks Cantonese and Spanish. Some of her hobbies include gardening, traveling, and spending quality time with friends and families.
