She was born to be a grandma, affectionately known as Grandma Dragon. Her eight grandkids were her 'little diamonds'. She had an amazing ability to interact and be a kid with them. Deb loved having her family together for holidays and birthdays. She enjoyed creating ice cream birthday cakes for these special occasions. Her yard was also her pride and joy and it showed. Deb loved making things beautiful for others to enjoy. She lived for the summer when she could be outside working on making it perfect. Deb will be remembered for her quick wit, jokes and pranks, and making people laugh. Her spirit and love will never be forgotten. She was preceded in death by her parents; brothers, Gary and Lynn Peters; sister, Beverly Behr; and nephew, Steve Peters.
