I recommend checking out Give Back Cincinnati. Give Back is a volunteer group of young professionals with more than 5000 members who live or work in Greater Cincinnati and who are typically between ages 18-35. Give Back Cincinnati is a great organization for young professionals who are new to town as it not only gives you an opportunity to give back to your community, but also offers social opportunities as volunteer activities are typically followed by a social after event.
There are also a number of organization-specific young professional volunteer groups, such as Cincinnati Habitat Young Professionals, a volunteer organization working to raise money, awareness, and volunteer for Cincinnati Habitat for Humanity. YPACS, Young Professionals of the American Cancer Society is another group that volunteers, raises money, and awareness for the American Cancer Society, as well as offering social networking opportunities for young professionals ages 21-45.
