Sarah is the Owner and CEO of SGB Acoustics LLC. She has been working with the Swiss company Topakustik and their products for fifteen years. She received her Master of Arts in Audio Sciences with a concentration in Acoustics from The Johns Hopkins University. She also received her Bachelor of Music Education from the University of Georgia. Sarah began her experience in the acoustics industry with an internship at Kirkegaard Associates where she was introduced to the field and sparked her love for the marriage of acoustics and design. She has been working in the construction industry with acoustics for the past fifteen years and has had the pleasure of working on projects from nearly every market in construction and countless design firms. She still has a passion for educating the architectural community about sound and how sound can improve the function and experience of a space.


Bill is the design coordinator for SGB Acoustics LLC. He logged five years of experience with Topakustik’s products before a two year hiatus designing rigging elements for touring productions in the live entertainment industry. He earned his Bachelor of Science in Architecture from the University of Maryland, which bolsters his ability to work with architects to achieve their visions. Bill believes that our sense of place is as much influenced by our ear as by our eye and that these two areas need equal weight in the design phase. Working closely with project managers, Bill helps clients achieve spaces that are both beautiful and comfortable.
