Her devotion was evidenced through her praying of the rosary with her group, prior to mass and at home.  Theresa will be remembered for her joyful spirit, outgoing personality, and her genuine kindness towards others. She was a lover of all animals, especially her late Labradoodle Chloe who she enjoyed taking on walks and to the park. Her love of sports started at an early age.  She enjoyed playing softball and even considered playing it professionally.  When her grandchildren were younger, she enjoyed watching and cheering them on in their various sports; she was such a proud grandmother.  She loved her weekly bowling and fellow bowlers and was always excited to share her score with us even if she thought she did not bowl well.
