Meet the Team

Tracy Armstrong, M.A., CCC-A

Director of Audiology

Tracy received her Master’s Degree in Audiology from the University of Texas in 1992. Throughout her career, she has worked extensively in the areas of aural rehabilitation, amplification services, diagnostic testing, vestibular evaluation, tinnitus management, cochlear implants, and bone- anchored auditory prosthetic devices. Tracy has taught hearing loss coping skills classes to the community, she has served as the American Tinnitus Association’s San Antonio representative, and she has been a guest speaker at many SHHH (Self Help for Hard of Hearing) meetings.

Developing a personal relationship with her patients is what Tracy most enjoys about working as an audiologist, and she works hard to understand each individual patient’s communication needs and challenges. Tracy believes that helping people hear is a combination of appropriate technology, guidance, listening, adjusting, and empathy.

Tracy is the proud mother of twins. Her son Jeb is at the University of Texas, studying biology. Her daughter Sadie is at the University of Washington, studying bioeconomics. Tracy dedicates much of her spare time volunteering: she has served on the RRISD Bond Oversight Committee and the RRISD Safety and Security Task Force. She has volunteered as a master naturalist where she spent time recording the habitats of salamanders and has fostered puppies through Austin Pets Alive. Tracy loves to backpack and cook in her spare time.

Sabrina Olivia, Au.D., CCC-A,


Sabrina Olivia received her Master’s Degree in Communication Sciences and Disorders at the University of Texas at Austin and her Doctorate of Audiology at Arizona School of Health Sciences. She has had the pleasure of working both in the private practice setting as well as the ENT office setting. Her first exposure to audiology involved her father’s military service-related hearing loss and the role it played in their relationship. Once he received and began to use hearing aids a new world of communication opened up. The resulting benefits her father enjoyed solidified her desire to help others achieve the same success in their personal and professional lives. When not at work, Dr. Olivia enjoys cooking, reading and spending time with her husband, cats and dogs.
