anita high


about Anita

Anita High was hired on staff in May 2022 as the receptionist here at GCC. Anita and her husband Tim started attending Grace about 3 years ago after attending special events with their son and daughter-in-law, Justin and Shayla High. They also have a daughter, Rebecca High.

Anita enjoys reading, gardening, and all things art (music, films, and dance to name a few). She has an associate degree in Biblical studies from Lancaster Bible College. She is currently enrolled in the Colson Fellows Program at GCC where she is being challenged by the “renewing of her mind” to engage in cultural issues. Colson Fellows represent Christians from every walk of life who desire to understand the culture and know how to live and act faithfully within their respective spheres of influence.

A slightly unusual life verse was chosen at age 16 while at “training camp” with Teen Missions in the “jungles” of Florida where she faced a literal 12-foot wall. Psalms 18:29 says- “with your help I can advance against a troop; with my God I can scale a wall.” While not involved in sports in her teens, Anita found running in her late 30’s to be of great help in mental health as well as physical health. Although not currently running, she took the challenge of a marathon in 2013 and counts that finishing medal to be proof that we are often capable of more than we think. Acts 20:24 finishes with- “my only aim is to finish the race and complete the task the Lord Jesus has given me- the task of testifying to the good news of God’s grace.”
