I Was Very Impressed With Him
After my previous Doctor of 5 years left the practice I was left with finding another Urologist. My fiancée recommended Dr King knowing him from a prior experience. Of course I was apprehensive having had four prior surgeries for bladder cancer. Upon meeting Dr King and having my first cyscoptopy I was very impressed with him and the procedure. Dr King took the time to explained my prior medical history and recommend an ongoing program to keep me cancer free. No guarantees, but much hope.
