Doctors & Staff
Meet our friendly and knowledgeable doctors and staff who make Deer Park Vision Source the leading provider of vision care in Deer Park.
Michael De Rosier O.D.
Dr. DeRosier is an active member of VOSH. VOSH stands for Volunteer Optometric Services to Humanity. This is an international organization that is striving to eliminate avoidable blindness in our world today. VOSH/International signed a declaration with the World Council of Optometry and the World Health Organization in 2001 to achieve this by 2020. Each year, VOSH chapters average between 80 and 90 missions serving in excess of 100,000 people.
Dr. DeRosier began serving with VOSH in 1986. He previously sat on the VOSH NW Board and was president of the chapter. Today he sits on the International Board and chairs the Technology Transfer Program (TTP). TTP accepts optometric equipment donations. They take this equipment, ensure that it works well, refurbish it, and then send it to clinics and schools in developing countries. Their goal is to educate future optometrists in developing countries and to give them the tools necessary to establish a good practice. This program was founded in 2006.
As a member of VOSH, Dr. DeRosier has had the opportunity to travel on several eye missions over the years. He has been to Honduras, Nicaragua, Guatemala, and Samoa. For each mission, a team of 16-22 people travel to a developing country and do eye exams. If a patient needs glasses, the doctors give them donated glasses that are similar to their prescription. Our practice is always accepting gently used prescription glasses for these missions.
