Growing up as a young man, Ross farmed for many years. He then worked at the Mayo Clinic for 25 years. After retirement Ross and Delores moved to Osage, MN where his family helped build the family cabin. During winter months, Ross and Delores spent time in Yuma, AZ. Ross looked forward to family coming to visit. Ross enjoyed playing softball, bowling, hunting, fishing from his pontoon boat, and traveling the United States in their RV. He was an avid Minnesota sports fan and made sure he never missed a Twins game. Ross will be remembered as a quiet man with a huge heart, a warm smile, and always willing to listen to what you had to say.
