Tia Harris

Regional Food Service Manager

Chef Tia began her “Culinary” training early in life, as a child at her Grammy Ethel June’s apron strings. Raised in Central PA, she has always had a passion for good ole home cooking, Pennsylvania Dutch Style.

At the age of 16 she decided her future pursuit by enlisting in the US Army Delayed Entry Program as a Culinary Specialist. Upon graduating from High School, she left for US Army Basic Training to be followed by Advanced Individual Training and finally Airborne School.

Chef Tia’s Honorable Military career spanned 12 years Active Duty, plus 6 years as a DOD Contracted Advanced Culinary Instructor at the Joint Center of Culinary Excellence, Ft. Lee, VA. During her Active-Duty career, she experienced several deployments, and assignments that took her around the globe and back. She credits her amazing Grandmother and the US Army with her success personally and professionally.

Aside from “Foodie” interests, Tia has a passion for American Football (Steeler Nation!!!), and she found herself in the greatest position (MLB) to have played for 4 seasons in the WFL/IWFL Women’s Professional Football Leagues “Cape Fear Thunder” while attending college in NC.

If you don’t find Tia happily creating in her “State of the Art” Linglestown kitchen…. you’re sure to find her online shopping (for eye shadow) lol or relaxing with her awesome cats, TomHardy and Sassyfrass.
