Our Team

Our combination of training, breadth of experience, and leadership is unmatched by any other firm in our primary service area. Senior Principal Consultant Dr. Noral D. Stewart, FASA, FASTM founded the firm and is now offering limited services in semi-retirement. He is an internationally recognized leader involved in the study and practice of acoustics since 1967, consulting full time since 1981 and a past President of the National Council of Acoustical Consultants (NCAC). Principal Consultant Joe Bridger has been with the firm since 1993 and now manages operations. He has for many years led our work in architectural acoustics (room acoustics, HVAC noise control, and sound isolation), including performance spaces, worship spaces, and schools and is currently serving as a vice-president of the NCAC. Senior Consultant Dr. John Gagliardi has over 25 years of experience in acoustics. John Gagliardi leads our environmental investigation efforts, and provides critical support for architectural acoustics and field investigations from his office near Charlotte.  Consultants Ezra Blackwell and Siddharth Mahajan provide strong support with field investigations and computer modeling.  Fred Schafer of F. C. Schafer Consulting is located in our office. He started working with us on audio and other technical systems over 30 years ago and also assists with room acoustics. Others frequently assisting under contract include former employee Mathew George (MMG Acoustical Consultants), Dr. Richard Honeycutt, Dr. Howard Quinn and Dr. John Stewart who specializes in industrial workplace and machinery noise and vibration control.

We have built a close network of acoustical consultants around the country that we can bring on board for specific project demands or skills.  We deliberately recruit highly skilled independent consultants who share our vision to join our team on projects so that we can always bring the best quality to every project and meet client needs. Our active participation in technical, professional, and standards organizations provides contacts and current technical knowledge of developments in our field.
