Grand Slam Signs started off as a small sign business with the goal of achieving growth by word of mouth and award winning smiles. 

Grand Slam Signs uses a massive, popular, and established manufacturing company to produce the signs and marketing material for their customers.  Because Grand Slam Signs doesn't have a store front, equipment, or overhead, they are able to get you the best quality signs and marketing material at wholesale prices.

In 2016, Heidi James joined C.J. in building his business.  Heidi's degree is in education. Turning away from the Common Core train wreck, she was in search of a new path. Having previous sales and manager experience, she jumped at the opportunity to use her teaching grit and people skills to start a new chapter in her life.  Heidi sat down with C.J. as he taught her the ropes so that she could own her very own Grand Slam Signs.  Although they have different kinds of customers, both offer the same products, quality, and desire to make their customers shine.  Heidi currently resides in Arizona but also travels often to see her customers in Texas and Connecticut.  Heidi also owns and operates Buttercup Designs.  Buttercup Designs is a graphic design business.  From website design, to logo design, Heidi does it all.
