Today is the day! Our longtime manager, Shari (also sometimes known as NOT Alyssa’s mother lol) is retiring! For over 40 years she has been an absolute staple here at Gregg’s, and we cannot express our gratitude for her hard work enough.

There were countless people that have came and went throughout the last 50 years of serving the community our sandwiches. But Shari, along with Cindy and of course Connie, was the final piece of the 3 gals that paved the way for the next generation and helped make this place what it is today.

You can still stop in and see her on Saturdays for a little while yet, but join us today in congratulating her on her day! Congratulations Shari!
