He has a solid understanding of what they’re facing and puts himself in their shoes to tackle their problem with the utmost level of care.

A WAY TO DECOMPRESS
Wilhelm has been knitting since he was a kid. He learned from his mother and grandmother and has kept it up to this day. He is an avid runner and walks five miles to and from the office each day. He uses knitting, running, and walking as a time to decompress, work through thorny issues and recharge his mental batteries.
