I showed up for the walk-in clinic, thinking it was directly affiliated with the dermatology facility. Once I went thru the appt and realized I actually needed to see my dermatologist, they got me back in same day, which I really appreciated. They always run on time, and are extremely efficient. This dermatology office is amazing and I drive a fair distance to receive this type of care. Well done!
