This focus on mission continues to push the importance of oral health to our members and has allowed for the continued growth of our business.
Whether through the growth of our Medicaid partnership, which brought affordable oral health care to more families, team efforts to ensure passage of legislation in Michigan requiring oral health screenings for incoming school children, or the growth of membership in our commercial lines—staying true to our core provided a year of great performance.
Growth, always an important goal, continued in 2023. Across Michigan, Ohio and Indiana, we grew by more than 250,000 subscribers and more than $146 million in new revenue.
We added more than 1,900 groups to our member roster while achieving an exceptional 99 percent retention rate of existing members. DeltaVision®, in its second year of existence, saw steady, appreciable growth as well adding nearly 800 new groups and more than 38,000 subscribers.
We are especially proud of the work we do to bring oral health care to underserved communities and the role we play in administering multiple government programs.
In 2023, Delta Dental retained 100 percent of existing government customers while adding more than 170,000 new Medicaid members.
Delta Dental employees set a new standard for employee giving, with an incredible 67 percent of staff members donating time, money or both to charitable activities.
The Delta Dental Foundation contributed nearly $7.5 million to benefit oral health education in 2023, impacting more than 2 million lives.
In 2023, we brought a new outlet to our provider relations efforts with the launch of Best Practice, a journal focused on dentistry, business and policy. In addition, more than two dozen dentists and dental office staff across Michigan, Ohio, and Indiana were recruited to review, evaluate and contribute to strategies for all Delta Dental provider communications tools.
With a calm, consistent, and confident approach to our business initiatives, we delivered for our customers, partners and stakeholders in 2023.
Delta Dental of Michigan, Ohio, and Indiana spent a significant amount of time and effort in 2023 on the execution of our strategic plan. Every effort, every project, every decision was guided by this plan and the results speak for themselves.
There's always more to numbers than meets the eye and that is the case here. Behind every number was tremendous effort from Delta Dental staff.
