How likely are you to recommend Dr. Long?

(Select your rating)
Dr Long is a very, very excellent doctor. He found out things other doctors never took the time to look into, but when he found out. He got to the problem and got it under control. The problem I have was very rear and a lot of doctors couldn't find out, what was going on. But when Dr Long came a long, he knew just what to do. I was experiencing spams in my heart. It's hard to explain, because the symptoms comes and goes. He did all types of tests and found the problem. I truly missed him.
