Rosalie fought many health battles throughout her life. She was stricken with polio when she was 12 and spent six months in the hospital. She had cancer more than 20 years ago. She was given a 5% chance of survival and had one of her lungs removed. Then, later she suffered three heart attacks. In 2023, she was in the hospital 7 times. During her last 2023 hospital stay her appendix had to be removed. Education was of the utmost importance to her. She was also an avid reader and thought books to be treasures. She loved doing crossword puzzles and playing games with her grandchildren. She was a regular at local trivia, and spent lots of time watching the Game Show Network. She was also a frequent attendee of her son Mark's concerts with his bands platinum recording artist KIX and Sun Dogs a Tribute to RUSH. She would sit there in her wheelchair enjoying every musical moment while cultivating a vibrant social network of fellow concert goers. She loved living on a lake and watching beautiful sunsets. Always wanting to entertain for family and friends, her annual Memorial Day picnics created lots of memories for everyone in attendance.
