About Us

Dr. Alison Black founded Las Colinas Dermatology over 20 years ago, in 1995, to provide medical, surgical and cosmetic dermatology care to patients in Las Colinas, Irving, Coppell, and the surrounding areas. Our nurse practitioner Brooke Smart joined Las Colinas Dermatology in 2013, after over four years in the field of dermatology. In 2020 our board certified physician assistant, Cheryl Sundlov joined Las Colinas Dermatology, after over 18 years in the field of dermatology. We want to thank our loyal patients and their continuing referrals that have made our practice flourish. Dr. Black, Brooke, and Cheryl focus on meeting the dermatologic needs of the entire family. This can include treating eczema, warts and birthmarks in children, acne in teens and adults, and rashes, skin cancers and signs of aging and sun damage in adults. We believe strongly in educating patients about their conditions, in addition to prevention and treatment. At Las Colinas Dermatology, Dr. Black, Brooke Smart, FNP, and Cheryl Sundlov, PA-C combine years of experience and compassion for their patients to provide the best in personalized medical and cosmetic dermatologic care.
