Office staff is AMAZING and probably the most professional out of all the medical offices I have ever been to! Their passion for patient care and willingness to help others is top notch. They are very accommodating to my busy schedule and are always running on time for my appointments. Great establishment all around, I highly recommend Foothill Dermatology!!!
