SCOTTSDALE, ARIZ. (August 21, 2019) – Sigma Contracting, Inc. continues to grow its staff and presence in the Southwest with the hiring of another superintendent and a new project manager.

Sigma is pleased to announce the hiring of Superintendent Ron Alderman and Project Manager John Russell. They each have spent 23 years in the industry.

Originally from Canandaigua, N.Y., Alderman will oversee the operations of his current construction site, the new Mountainside Fitness at 5320 E. Shea Blvd., Scottsdale. He will be responsible for daily scheduling, supervising all activities and tasks and ensuring the safety and compliance of the project site.

A native of Tucson who grew up in Pinetop, Russell will oversee a variety of projects, ensuring that plan documents are executed properly and that the superintendents and subcontractors have the proper direction and resources to meet deadlines. In overseeing their interests, Russell will collaborate with owners, employees and suppliers to oversee safety, adherence to schedule and budget.

“The demand for Sigma’s longevity of experience and expertise has led to an influx of projects that gave us the opportunity to bring on board this great pair of industry experts,” said Dan Hinkson, President of Sigma Contracting. “Together they bring a combined 46 years of experience and excellent skill sets. Just as we were thrilled to bring back Ben Gorbea, we are equally thrilled to have Ron and John join the team.”

Gorbea, who had previously worked for the Arizona-based general contracting company, was re-hired as a superintendent earlier this year. He is currently supervising a remodel and addition for Knight-Swift Transportation.

Prior to joining Sigma, Alderman worked at GCON Inc., in Phoenix, and Wasson Commercial Contracting in Mesa. He also worked at A.R. Mays. A member of the Army National Guard from 1993 to 1999, Alderman graduated from Hobart College in Geneva, N.Y. He earned a BA in economics.

Russell also joins Sigma from GCON, where, in addition to project management, he implemented, enforced and managed the company’s safety policy and procedures. He was director of construction for Children’s Learning Adventure.  The father of four boys, Russell is a youth basketball coach and enjoys camping, fishing and hiking.
