“Dr. Long is a highly experienced professional, you could tell it from his bed side manners and the way he communicates. He easily detected the cause of my skin rash and prescribed a working medication. I am very grateful. The wait time was less than 10 minutes.”

“Dr. Long was excellent! He took care of several skin tags as well as cysts.....painlessly. I was concerned as the tags were around my eyes, but was so pleased afterwards. He was also efficient but never rushed and answered my questions. Highly recommend. ”
