Been using Dr. Day since around 2005. His office staff is awesome and he is the best Dermatoligist around! He has done several Mohs surgeries on my husband…not even as much as a scar! His bedside manner is also great! Highly recommend!

I credit Dr. Day with "saving my face"! I had cancer on the side of my nose and then directly under my eye. He did Mohs surgery on both. No scars and no more cancer. I would never use another dermatologist!

Dr. Day has been taking care of me and my family for over 20 years. He is one of the most experienced and skilled dermatologists practicing Mohs dermatologic surgery anywhere. I trust his judgment and care absolutely. Harold Gaskill, MD
