Roberta Roberts Shank
Chief Executive Officer

“I love Chas Roberts!  It is wonderful to be a part of a family business, in particular with our team that works so well together – we are like a big family.  Everyone is focused on doing all we can to be the best, and we are energized by the future, and making great things happen.”

Roberta Roberts Shank, CEO of Chas Roberts, began working part-time at the company her grandparents founded when she was in junior high.  She became the company’s full-time computer programmer in 1987, and over the years has taken on many different roles.

Roberta was fortunate to work with her father for more than fifteen years, learning every aspect of the family business from him.  Today, she leads the company’s vision and growth plans, maintaining the same principles that her father emphasized: “being the best.” It is critical to Roberta and her team that Chas Roberts deliver the best service possible, and stand behind the products and services provided by the company.

Roberta is supported in this endeavor by an extensive team at Chas Roberts, including her management team and hundreds of others, many of whom have been with Chas Roberts for more than 15 years! These people have each been instrumental in growing the company and earning recognition in the industry, namely as Arizona’s Most Admired Company in 1997, Arizona Corporate Achievement Award, and Ranking Arizona Top Ten.

Outside of the office, Roberta and her daughter have been members of the National Charity League since 2005.  And, recently Roberta and her dog were certified as a Delta Pet Partner Team, through which they are able to provide comfort to patients and elderly residents at area hospitals and nursing homes. Roberta graduated from Arizona State University.
