Rosalind Sinclair, BC-HIS

Hearing Instrument Specialist

Rosalind, “Roz,” has been a hearing instrument specialist since 2001 and is Board Certified in Hearing Instrument Sciences. She serves the hearing impaired community in beautiful Vancouver, Washington. Designing custom, advanced technology hearing systems for thousands of hearing impaired patients is a joy, not a job, to her. Being exposed to the value of hearing aids at a young age due to her grandparents wearing them helped her to understand that hearing loss doesn’t just affect the person wearing aids but also their families, co-workers and friends. She feels so privileged to pair art and science in connecting people to their world of what matters most to them and their loved ones. Her favorite days at the office are when tears of pain and frustration of those in need are turned to tears of joy when they can hear and understand. “It’s a wonderful experience to have hearing healthcare done right.”
