Austin Eminhizer - Gary Bale Redi-Mix, Inc.

My name is Austin Eminhizer and I handle Sales & Operations at Gary Bale Redi-Mix, Inc. in Orange County. I am twenty-eight years old and have a bachelor’s degree in Entrepreneurship. I have been working in the concrete industry since 2012, and have loved every second of it (just about). At Gary Bale, my customer base is predominantly high end custom residential foundations and hardscape, but we cover a wide range of projects from backyard patios to massive stormwater channels. I learned in a hurry that comprehensive knowledge of the science and chemistry of concrete is vital to producing the best product possible, and to avoid a lot of headaches down the road. Much of my education in ready mix concrete is credited to both in-person training as well as online research with ACI professionals and resources.

My family has a history of involvement with ACI and I would love to be the next Eminhizer to carry the torch in the SoCal chapter. I believe this organization is fundamental to keeping our industry standards elevated as well as attracting upcoming generations to the concrete and building materials industry as a whole. Given the opportunity, I will make every effort possible to continue to advance the importance, quality, and popularity of this organization.
