David talked me thru a painful Saturday afternoon with several recommendations that helped but did not solve the problem. As a precaution he told me to go to the nearby emergency room.
I was at the emergency room about 30 minutes when David walked into the room. I was surprised (actually shocked) that he took time from his family on a Saturday evening to be with my wife and me.
He consulted with the ER physician and recommended a CT to rule out any serious problems. The ER physician concurred and the procedure was done.
While nothing was found causing my abdominal pain, the CT disclosed a mass on my kidney.
Long story short, David by his expertise probably saved my kidney and possibly saved my life.
David: I have told you privately thank you. But publicly I want you to know how grateful I am for you expertise and friendship.
