"I consider myself very fortunate to be part of a profession that enables me to give back so much not only to my community but also to the world community. This is what I enjoy doing when I'm not seeing patients in our office. Doing this type of work makes it possible for me to be so enthusiastic about what we have here at Brookside Optometric Group," he says.
Dr. Demshar has been married to his wife, Debbie, for over 30 years and they have 3 grown children.
