History and Mission

Company History

The clinic was established in 1952 by Mr. Elwood Mark. Being a hearing impaired person himself, he wanted to help others to hear. His son, Ian Mark, joined him later in his practice.

In 1987, Céline Lachance finished her hearing care professional course and found with Mr. Mark the same passion and desire to help that she always had. She therefore joined Mr. Mark's team and continued to serve people with devotion and generosity. Her mission is to improve the quality of life of all the people around us.
