She was a member of the Congregational Christian Church in Stillman Valley and was recently attending Roscoe United Methodist close to her home. Dorothy will be remembered for her big heart who wouldn’t even kill a fly. She loved all animals especially cats and horses which she used to show. She was known for personally rescuing any cat in need as well as volunteering with various animal rescues in the area. She enjoyed camping, biking, and hiking; making sure to always stop at waterfalls during her travels. She was proud of her extensive collection of Breyer Horses and anything cat related. Dorothy was independent and persistent especially when playing the claw machine games. She would not stop until she won a stuffed animal. But, most importantly Dorothy loved her family above all else. She was a dedicated wife, sister, aunt, and friend who never missed family game night and would stick her tongue out any time a camera was pointed at her. She leaves a lifetime of memories with anyone who loved her.
