Why I Work at Wilson Ihrig

“I admired Wilson Ihrig’s work from a technical and professional standpoint for over a decade before I was fortunate enough to join the firm in 2015. I’ve always appreciated their technical knowledge and innovative approaches to acoustical projects, and find it exciting to now have the opportunity to learn directly from all of my colleagues at Wilson Ihrig. I look forward to many, many years to come supporting our clients as a contributing member of this firm.”
