The worst choice we ever made. Choosing this doctor. He dropped the ball. Delay after delay - 1 year of uncaring and miss diagnosis caused the cancer to leave the prostrate. Now 5 yrs later still fighting the cancer. Always get many opinions and make sure your doctor stresses the repercussions of radiation instead of selling you their surgical specialty. Moffitt interviewing was like buying a car...I had to hit a 'star' to get this posted...fyi

We were able to discuss options in a realistic way, give my circumstances. I think he is good. [...]

Dr Johnstone is candid but kind; to the point but gentle; no-nonsense but very empathetic. He can take something complicated and explain It In a way that's easily understood by someone who Is non-medical. He's an amazing, caring and competent doctor. I recommend him without reservation.
