Brad was one of the first users of a program I was working on, which he used for his work at Sandia National Labs. He would send me frequent, detailed feedback - respectful and kind, inquiring about possible solutions he'd thought of. He even invited me to Sandia to give a talk together about these efforts [1]. I've never had a kinder customer. [1] https://www.sandia.gov/xr/4th-annual-xr-conference/agenda/ https://www.sandia.gov/xr/4th-annual-xr-conference/agenda/
