Lou Andreadisis returning for his ninth season at Grand Valley as a full-time assistant for both men's and women's track and field. Andreadis' experience is a valuable resource to the Laker program and will also reunite Andreadis with head coach Jerry Baltes as they coached together at Butler University in Indiana. Lou's main responsibilities are to work with the Laker pole vaulters and handle all Multi-Event scheduling for the Combined Events.

At Grand Valley State, Andreadis has developed a solid vault program which has seen 23 all-americans in seven years and set both men's and women's school records . His vaulters average a fifteen inch improvement over the last seven years. Three vaulters have seen over three feet added to their high school PR's. Under Lou's coaching, Bryant Wilson went from a 14'6" high school vaulter to clearing 18'0.5" (5.50m) in 2009 and competing at the USATF National Championship. The same year Dianna Noonan, a 12'0" high school vaulter, cleared 13'9.25" (4.20m) and also qualified for the USATF Championship.

Coach Lou has also put together one of the largest pole selections in the entire country. Over $50,000 has been spent in poles alone to fill out complete series of poles from 12'6-16'1. He also helped design the lay-out for the two raised runways used at GVSU's indoor facility.

Andreadis graduated from Butler in 1996 with a degree in Secondary Education. Lou stayed at Butler and worked for four years as assistant coach for track and field and football as well as a part-time teacher at an Indianapolis grade school, IHM. In 2001 he was the head girls track and assistant football coach at his alma mater, Anderson High School in Cincinnati, Ohio.
