Teresa Marie Koshurin, 65, passed away on Wednesday, April 22, 2026, in Fort Wayne, Indiana. Born in Fort Wayne, Teresa was a daughter of the late Carroll and Frances (Byers) Runnion.
She graduated from Northrop High School, Class of 1979. Teresa began working at McDonald’s in 1995, where she would go on to dedicate the next 30 years of her life. Through hard work and determination, she became the general manager of the McDonald’s in Churubusco, where she built lasting relationships with coworkers, customers, and the community she served so faithfully.
Those who knew Teresa would describe her as a feisty, straight shooter who always spoke her mind. At the same time, she had a generous heart and was always willing to help others in any way she could. She had a way of leaving a lasting impression on everyone she met.
Outside of work, Teresa found joy in being outdoors. She loved yard work, landscaping, and gardening, taking pride in creating and caring for her surroundings.
She is survived by her children, Elizabeth (Jeremy) Thomas and Eric (Natalia Schuette) Koshurin; grandchildren, Dominick Thomas and Madelyn Grace Koshurin; sister, Pam (Shane) Randol; and nephew, Jason Randol.
Teresa was preceded in death by her husband, Alexander Koshurin, in 2016.
