About JSA Company

When John Sullins founded JSA Company over 40 years ago, he could not have imagined how the company would prosper. The same values that were established then are the basis on which this small company would become a leader in its industry in Southwestern Arizona. Those values of honesty, integrity, and hard work have maintained JSA as they were carried on by John’s brother Larry, and now his nephew Doug. The company not only has generations of passionate owners maintaining a genuine family atmosphere that has attracted long serving employees including sons that have followed in their father’s footsteps to be amongst some of the best staff in Arizona with JSA Company. These are some of the reasons JSA holds such a strong reputation with our many established, satisfied customers, and the respect of our competitors.
JSA works to uphold its reputation by the advancement of skills and knowledge through continued training and education supported and encouraged for all team-members.
