In 2020, Volman was diagnosed with Lewy body dementia (LBD), a progressive brain disorder that affects thinking, memory and movement.

“I got hit by the knowledge that this was going to create a whole new part of my life. And I said, ‘OK, whatever’s going to happen will happen, but I’ll go as far as I can,’” he told People magazine.

‘The challenges of this world affect everybody, and it’s been kind of fun being on the other side of a challenge like this and saying, ‘I feel good.’ My friends are here. I’m still here. And I want people to connect with me.”

Volman is survived by partner Emily Volman, his ex-wife Pat Volman, their daughters Hallie Volman and Sarina Miller and his brother Phil Volman.
