## About

Darkmoon Building Design & Engineering was established in 2008. We are a one stop shop for your design and engineering needs. Jonathan Villegas, owner and licensed professional engineer, started his firm after working in the industry since 1995. Jonathan has worked on projects abroad and within the United States. Since the inception of Darkmoon Building Design and Engineering, the firm has worked mainly on local projects.

Our ultimate goal for any project is to work cohesively and cooperatively with owners, design professionals, and contractors. Any project is a team effort; therefore, we encourage input from all stakeholders throughout the design phase. We take a “hands-on” approach and often meet at the site to discuss options or solutions to items that inevitably come up during construction. This is especially true for remodels and additions.

We look forward to working with you on your next engineering project.
