Our Professionals

Only AudigyCertified™ practices have access to AGX® Hearing technology — always the most advanced and effective technology available.

But great technology is just the beginning for us. Understanding the way you live, your personal hearing needs, and the better-hearing goals you have for yourself helps us craft a more personalized and comprehensive hearing solution than anyone else can offer.

Terry M. Martin


Throughout the years, I have made it my mission to provide the best hearing care services possible to each of my patients. In addition, I have always made an effort to contribute to our community in other ways by participating in various local organizations and supporting the Easter Seals Rehabilitation Center. Outside of work, I enjoy running, photography and traveling with my wife.

Sigourney Brinkmann

Office Manager

I have been in the health care field for several years, working with clients of all ages and disabilities. In 2013, I began working as the client service representative for Hearing and Speech Associates, Inc. This was a perfect fit for me since I have always enjoyed working with patients to help meet their needs.


Front Office Staff

I love the interaction I get to have with our patients. I understand the hardship of being hearing impaired because I myself suffered from hearing loss until I was in the fourth grade. I enjoy learning about the auditory system and different hearing loss treatments.
