Jash Design & Build Company
Founded in 2009 by Ash Moeini, Jash Design & Build has grown from small renovations into a full-service design-build firm serving residential and commercial clients. Our foundation comes from Ash’s lifelong experience in construction, from learning on job sites in Iran to working on residential, commercial, restoration, and government projects in New York. Over the years, we expanded into restaurant renovations, building 22 Wild Wing locations, followed by law offices, dental and medical spaces, additions, custom homes, and full ground-up builds. Today, we bring that history into every project with strong management, experienced trades, and a do-it-right mindset.
