Sarita Nori, MD (Dermatology)

Dr. Sarita Nori was drawn to dermatology because of the intersection of science and medicine that is at the heart of dermatology. She feels this is what really allows her to help her patients. “There is a lot of problem-solving in dermatology and I like that,” she explains. “It’s also a profession where you can help people quickly and really make a difference in their lives.” | Some of the typical skin problems that Dr. Nori treats include skin cancers, psoriasis, acne, eczema, rashes, and contact dermatitis. Dr Nori believes in using all possible avenues of treatment, such as biologics, especially in patients with chronic diseases such as eczema and psoriasis. “These medications can work superbly, and they are really life-changing for many patients.” | Dr. Nori feels it’s important for patients to have a good understanding of the disease or condition that is affecting them. “I like to educate my patients on their problem and have them really understand it so they can take the best course of action. Patients always do better when they understand their skin condition, and how to treat it.”
