Dan Speck and Dan Vermeer founded Alta Southwest, after they were happily retired. The last thing on their minds was starting a business… until they both realized that their contacts in the industry and business management expertise could be the start of something great.

With offices in Tucson, Phoenix, Florence and Sierra Vista, our staff includes 5 registered land surveyors, 26 certified material technicians & inspectors, and 6 professional engineers.

“When we were first starting out, I was thinking bigger picture about our company and soon realized I needed to seek help putting processes and policies in place to ensure the well-being of our employees” – Dan Vermeer

“We’ve worked to attract the best employees in the business: technicians, engineers, inspectors and surveyors…  and we want our employees to feel that they have a meaningful career with our company” – Dan Speck

The Alta Southwest engineering staff has over 100 years of project experience involving residential, commercial, government, and industrial projects.

We look forward to working together!
