It has been said that you should choose a doctor about your own age so that you get the same illnesses at about the same time, so he/she knows what you are talking about.
Dr. Barry Webb became my personal physician over 25 years ago after being highly recommended by his wife to my wife. :-) Lois and I had two prior bad experiences. Dr. Webb evolved into a caring friend and physician from just being a plain young doctor years ago. What more can I say?
Pros: It is nice when a doctor really cares and takes his time.
Cons: Waiting. Dr. Webb gives extra time to those in need.
