Theresa M. O’Brien-Messer

Theresa was known best in the community for her work at the Knox Veterinary Clinic and as a Substitute Teacher for the local schools. She had a supreme love for horses and dogs, and shined brightest doing that work.

She was preceded in death by her father, Patrick O’Brien of Palos Hills, Illinois, her mother and step-father, Joan and John Themascus of Knox, her sister Kathleen Keenan (Larry) Atlanta, Michigan, and her brother, Timothy O’Brien of Knox.

Theresa’s final request was that she be cremated and there will be no viewing or services. Memorials may be made to the family or to the Starke County Humane Society in North Judson, Indiana. M.C. Smith Funeral Home in Knox in handling arrangements.
