TO THE EDITOR:As several of you know, Dr. Ray Troop will be retiring on April 30. He has been taking care of the people in Warren and surrounding counties for almost 50 years.I would especially like to thank him for taking care of me and my wie, Vilas, for almost 40 years.In 1988, he found a knot on my neck and sent me to the hospital for a thyroid scan. The technician said the scan didn’t show anything.
