Open Doors Organization (ODO) first came to national attention for its groundbreaking studies of travel and hospitality among American adults with disabilities. Until the first ODO study in 2002, there had never been a major, statistically reliable survey on the US disability travel market. A second study in 2005, using the same methodology and conducted again by Harris Interactive, confirmed the market size and travel patterns found in 2002. It also extended the research into new areas including overseas travel and how adults with disabilities research and book their trips.

Reports from both studies are available for purchase. These remain the only such studies focusing exclusively on long-distance travel and the barriers still facing Americans with disabilities in airports, airlines, hotels and restaurants. The next nationwide ODO Market Study is planned for 2012 and sponsorship opportunities are available.

In addition to its Market Studies, Open Doors Organization regularly conducts focus group research, both for its own knowledge base as well as for clients. ODO can also provide mystery shopping to help companies test their customer service for clients with disabilities.
