DACdb was started in 2003 by the late PDG Mike Thacker. He wanted to give his District the ability during his year as District Governor to manage their membership themselves. At the time, Rotary International offered no such viable option. Very shortly there after Mark Landmann, a Senior Developer came along to help develop the system. The rest is history as they say.

As an official Rotary International Licensee, DACdb takes care of your member management and helps you focus on your goals and service to your community. DACdb also helps districts and clubs around the world improve member communication and community outreach. Less time / less stress is the key to your Rotary success! With support working 7 days a week, we have you covered.
