Katia Peeters

Obtained her degree as a Speech Therapist and Audiologist in Europe where she worked for many years in the hearing industry and specifically trained as an audiologist and worked with ENT in the fitting of cochlear implants.

Siemens Hearing Instruments invited her to come and live in Australia to train audiologists in the technology and fitting of hearing aids.

After several years of intensive travelling and presenting seminars in Australia, she decided to settle in Brisbane and re-focus again on the clinical side of her work. Falls of Sound in Indooroopilly had been operating very successfully, and Katia and her family moved to the Sunshine Coast where she opened Falls of Sound Maroochydore.

Katia’s priority in the business is to make sure that every client receives an outstanding experience in their “journey to better hearing”. Therefore she is constantly training herself in the latest technology of all brands. She appreciates the client’s feedback, so a further comparison between products can be analysed.
