Dr. Channie Duhn

Dr. Channie Duhn - For 20 years, I have enjoyed serving our community and our time together. Now, my family and I have made the decision to begin our next chapter in Australia, which we’re very excited about. I will miss each of you and the amazing team here at Marin Optometry. I take great solace and excitement in being able to pass the baton to Dr. Jean Brennan. Together with Sharon Segal and the whole team, I can, without hesitation, embark on this journey knowing you’re in the best of hands. I have watched many of your children grow up, have benefited from the much-needed advise on raising my young sons and enjoyed years of counsel and conversation, which I’m ever grateful for. With gratitude and love Channie
