Throughout his career, Dr. Carr wore many hats.  In addition to his vererinary practice in Montfort from 1956 to 1988, he was President of the Wisconsin Veterinary Medical Association and Chairperson of the American Veterinary Medical Association Executive Board.  In 1979 he was the recipient of the W.V.M.A. Meritorious Service Award and in 1983 he was the Stange Award Recipient - Outstanding Veterinary Alumnus Award from Iowa State University.  In 1988, Dr. Carr was appointed the State Veterinarian for Wisconsin and remained in this role until his retirement in 1993.

   He was a longtime member of the Montfort Village Board and also a 4-H leader where he helped his children show award-winning angus and crossbred steers including a Wisconsin State Champion Hereford.  Dr. Carr was also President of Carr Farms Inc. and was a 23-year member of the Livingston State Bank Board.  In retirement, Dennis enjoyed selling granite monuments to friends as well as fishing, hunting and playing his fair share of card games.

   Marilyn was a big part of her husband's large animal veterinary practice and also was very involved with church activities.  All her grandchildren had much fun teasing her, asking if they were her "favorite" and she always denied so, saying she loved everyone equally the same.
