“Communication defines who we are and how we relate to others. I want to help enable everyone to communicate and make a difference in the world.”

David Niemeijer

He has a PhD in Agricultural and Environmental Sciences, but turned to developing assistive technology after a friend of his became paralyzed in a car accident and needed an on-screen keyboard for his Mac. He founded AssistiveWare in 2000. David has dedicated his life to the development of universal access and augmentative and alternative communication solutions in close collaboration with the community AssistiveWare serves. He is a frequent presenter at AT and AAC conferences worldwide.
