About ADSO


ADSO member organizations are building a future where dentists have the ability to choose the administrative support services which best allows them to focus on patients, expand access to quality dental care and improve the oral health of their communities.


Support ADSO members through research, education and advocacy; enabling them to foster innovation, collaboration and a vibrant market where DSO-supported dentists can provide quality oral health care.


The Association of Dental Support Organizations (ADSO) is a non-profit organization comprised of more than 40 member companies and more than 100 industry partners.   ADSO represents Dental Support Organizations (DSOs) before the public, policymakers and the media.   Our members enable supported dentists to focus on their patients and expand access for dental care while maintaining the highest standards of business and professional ethics.  Our members operate in 44 states and provide the highest level of non-clinical support to more than 13,000 dentists across the country as well as in Australia, Canada, New Zealand and the United Kingdom.  DSO-supported dentists, on average, have lower startup costs for a new practice, spend more time on clinical care within their practice than their non-DSO supported counterparts, and offer more flexible office hours for their patients.   ADSO is the source of information regarding the role DSOs play in the evolving dental services marketplace.


The Dental Service Organization model traces its roots back to 1975 when  the ADSO’s founding member, Affordable Care, Inc., supported its first dental practice. Since that time dozens of DSOs have opened and expanded throughout the world to take on the important work of supporting dentist in expanding access to quality dental care, improving the oral health of their patients, and reducing the cost of dentistry. The timeline below marks notable moments in ADSO’s development.
