About Us

Pattison Engineering, LLC was founded in Tucson in 1993 to provide local designers and builders with alternatives to the traditional way that soils engineering was practiced locally by the larger, corporate geotechnical engineering firms.

Partners Ralph M. Pattison, P.E., Francisco J. Jacinto, P.E., and Guillermo M. Marquez, P.E., believe that there is more than one way to approach a building project. Ralph M. Pattison founded the firm in order to provide designers, builders, and owners with solid, reliable, proven engineering advice, without advising typically overbuilt foundations which cost owners more to build, while providing no engineering value.

We are the largest locally-owned Geotechnical Firm in Tucson. We would love to work with you on your next project!
