The Diamond Awards started in 2006 to help raise money for research and education in brain, nerve and muscle disorders for the University of Minnesota; the organization has raised nearly $4 million during that time. The annual banquet has been replaced by a virtual awards ceremony for the past two years because of the pandemic.
