Roy Braun

Message from our Audiologist

During my four decades working in the field of Audiology, I have come to appreciate the importance of good hearing in maintaining my clients quality of life. I understand that my clinical decisions are extremely important to my clients. When people put their trust in me, I will always try to exceed their expectations.

Roy Braun is a registered Audiologist with over 40 years experience, including 17 years as the head clinical audiologist in a teaching hospital as well as 11 years as Director of Audiology at St Joseph’s Hospital in Peterborough. Since 2002 Roy has had the pleasure of providing audiological testing for patients of all ages at The Medical Centre. Our clinic has registered Audiologist, a Communicative Disorders Assistant and a Hearing Instrument Technician to provide patients with a caring approach to improved hearing for life.

Katherine Braun


Katherine completed an undergraduate degree of Honours English Language and Literature at Wilfrid Laurier University as well as and OTA/PTA diploma program at Sir Sandford Fleming College before following in her father’s (Roy) footsteps into audiology. She completed her clinical Doctorate of Audiology at Syracuse University in 2017 and happily rejoined the Medical Centre where she had worked (in various different departments) between stages in her education.

Why did you get into Audiology?

“I grew up surrounded by the profession with my father the audiologist and my mother a Speech Language Pathologist. Since my dad started this company I have helped out in various roles during summers and other school breaks. Over the years I found myself regularly drawn back to the business even when looking at other avenues of life. Finally I realized that there was a reason I was being drawn back and audiology is where I belong.”
