Semler Dermatology is located in a convenient spot on Deerfield Ave Avenue in Leesburg City. The office is well-equipped and has a wheelchair-accessible entrance, parking lot, and restroom. The staff seems to be knowledgeable and friendly.The working hours are a bit limited, with Friday closing early at 12:00 pm. However, it's great that they take NFC mobile payments, debit cards, and credit cards for payment.Unfortunately, the office has a history of frustrating patients with unexpected insurance issues. One patient had to cancel their insurance and switch to paying cash, which is unacceptable.On the other hand, some patients have had excellent experiences with the dermatologist, Dr. Douglas C. Semler, MD. He has performed successful surgeries with minimal scarring and has a reputation for being a great doctor.The office's planning suggests that appointments are recommended, which is a good idea considering the limited working hours. It would be helpful if they could communicate more clearly with patients about their insurance coverage.Overall, Semler Dermatology has some great qualities, but it's essential to be aware of the potential insurance issues that may arise.
