About Us

Gypsum Consulting  

is a sales and marketing firm that works with national companies to grow their businesses in specific markets. We are successful in what we do because we build and maintain relationships with their current and prospective clients through face-to-face communication.

What sets GCI apart from other companies? We are all about our people!  We don’t just want someone to come and do a job for us, we are looking for people who are ready to start careers.

When we interview someone for a position in our company, we are more interested in who they are, what they are looking to learn, and if they have the potential to be cross-trained in all aspects of business in order to move into a management position with us.  If the employee and employer are aligned, then both parties can be successful.  Our people get one on one mentoring from our owner and senior leaders to help them hit their professional goals.
