I was treated By Dr. Showalter for throat cancer and have been in remission for the past 4 years. Throughout my treatment and follow-up, I have been extremely impressed with his knowledge, compassion, and professionalism. I am proud to say I highly regard his friendship. I would therefore highly recommend him to anyone needing cancer treatment.
