Under the leadership of founding partners John Longman, Stephen Lindsey, Patricia Scanlon and Ken Shook, our growing firm of engineers is one of the largest and most prominent acoustical consulting groups in the United States. The partners have worked with each other for several decades and have a combined experience of more than 100 years. Each partner has a broad portfolio of project types, providing acoustical design for corporate, education, retail, hospitality, entertainment, healthcare, residential, and cultural spaces, as well as museums, libraries, studios, and environmental noise control. We take pride in offering concise, cost-effective recommendations to every acoustical design. Decades of successful projects— from complex, iconic buildings to unique troubleshooting endeavors—are a testimony to our experience, which is without equal.
