I survived skin cancer today thanks to Dr. Betty Davis and Dr. Jason Mussman and their wonderful staff. Drs Davis and Mussman are both very kind and made sure I was informed about the entire procedure and their medical assistants and staff made sure I was completely comfortable the entire time. Thank you so much to Dr. Davis and Dr. Jason Mussman for the wonderful care.

Such a great doctor! I got attacked by a dog and needed stitches on my upper lip! and he was very generous and nice. They all made me feel very comfortable! I really appreciate him getting me in on such short notice!
