Sigma Contracting, Inc. celebrates 35 years of building relationships, iconic projects across the Southwest

SCOTTSDALE, ARIZ.  –  Sigma Contracting, Inc., which has constructed more than 800 turnkey projects across the Southwest, is celebrating 35 years this fall of building relationships and giving back to the community.

Sigma Contracting was founded in 1983 and forged a reputation of honesty and integrity. Today it is a leading commercial general contractor that consistently exceeds the expectations of its clients. Under the collaborative direction of Dan Hinkson and Jerry Patterson, Sigma continues to flourish in a competitive market.

“We got into this business because we love what we do (in construction) and partner with good people to make exciting things happen,” Hinkson said.  “We are unique in that we chose our company size and project size to ensure that there is ownership involvement in every phase of a project, from business development and relationship building through to construction completion.

“We can make quick decisions and provide effective problem solving with solutions that are in the best interests of our clients. We have a vested interest in client satisfaction. After 35 years we are proud of our accomplishments on behalf of the clients we’ve served.”

Hinkson and Patterson were raised in “construction families” and at an early age gained valuable insight into the technical, managerial, and social aspects of the industry. They focus on treating people fairly, both personally and professionally. This is evident by the successful and long-term relationships they have forged with clients, subcontractors, and employees alike.

Hinkson founded a successful business and together with Patterson shepherded it through tough times during the Great Recession. While others downsized and shuttered their doors, they continued to provide a way for their employees to make a living and continue their families’ livelihoods. Sigma’s core employees have been partners with the company for more than 20 years, with many more than 30 years.

Stemming from a long-term relationship of building for and serving on boards with The Salvation Army, they created a legacy by being integral in bringing The Salvation Army Ray and Joan Kroc Corps Community Center to the community in South Phoenix that will help thousands of families improve their lives for years to come. From helping to write the grant letter and raising matching funds, to collaborating and assisting in the design and build of the center, it was an 8-year journey in partnership with The Salvation Army.

The center won AZRE’s 2012 RED Award for Best Public Project.

“I always told him (Dan) I would never work with him, but it’s been the greatest challenge and pleasure of my life,” said Melinda Hinkson, Director of Business Development / Marketing and Owner with Dan Hinkson, married for 41 years. “He is a good man with a kind heart and it has been my honor to work with the exceptional team of people he has assembled to help create community, camaraderie, and a sense of purpose, through good times and bad.

“Sigma is a great collaboration, and our reputation shows that we care about our people, our associates, and our clients as family. We work best with people of similar ilk,” Melinda Hinkson said.

Sigma continues to give back to the community. Dan Hinkson currently sits on boards for both Horses Help and The Beatitudes. Horses Help is an organization that provides the special needs community a therapeutic and recreational equine environment. The Beatitudes is a non-profit senior care facility in Central Phoenix.

Sigma builds in both the public and private sectors. In addition to “ground up” new construction projects, Sigma’s work consists of renovation, remodeling, and tenant improvements. Sigma provides pre-construction, design/build, general contracting, as well as project management and contracting services.
