About
Dr. Sharon Marchand is a board-certified dermatologist and Fellow of the American Academy of Dermatology with over 20 years of experience in medical and surgical dermatology. She grew up in New Orleans, where she attended the Academy of the Sacred Heart before earning her undergraduate degree at Tulane University in the Sophie Newcomb School. She then completed both medical school and her dermatology residency at LSU, training within the LSU Department of Dermatology.
Dr. Marchand practiced privately in Beaumont, TX for more than two decades before relocating to Dallas in Fall 2023. She still travels to Beaumont one week each month to see her established patients there. She treats skin, hair, and nail disorders across the full range of medical and surgical dermatology. Her clinical interests include acne, alopecia, autoimmune skin conditions, skin cancer, and complex inflammatory disorders. She approaches every visit with a commitment to thorough, unhurried evaluation. She prioritizes listening carefully, building individualized treatment plans, and making sure patients leave with a clear understanding of their diagnosis. Outside the office, she loves gardening, playing Rummikub, and watching Dateline. She describes herself as chatty and often blunt, and she means both as compliments.
