Coaches Bio: Coach Alvis Johnson (AJ) is a proud alumna of Life University, where she played collegiate volleyball as a DS/Libero from 2015 to 2018. As a member of Life’s inaugural women’s volleyball team, she helped lay the foundation for the program’s competitive legacy.

After graduation, Coach AJ transitioned into the medical field while continuing to stay connected to the sport she loves. She began her high school coaching career at Dunwoody High School, where she led the Junior Varsity team to a JV Championship.

During the pandemic, she began her Master’s in Teaching for Physical Education and accepted her first teaching position at Couch Middle School in 2021, where she not only taught PE but also developed the Grayson Volleyball Middle School Program and assisted her husband in coaching the boys’ basketball team. Under their leadership, both teams achieved top 3 finishes in Gwinnett County, a testament to her coaching ability across multiple sports and age groups.

Now serving as the Head Coach at Collins Hill High School, Coach AJ has made an immediate impact. After just one season, she was named both Region Coach of the Year and 6A Coach of the Year for Gwinnett County.

She is excited to continue building a culture of excellence for Collins Hill Volleyball — one focused on discipline, development, and love for the game.
