Has Anyone Followed John Boultwood’s Work on Complex Project Matters?

I recently came across John Boultwood while reading about construction and commercial project discussions, and it made me wonder what people value most when working with experienced independent professionals in challenging situations. Beyond technical knowledge and years of experience, do you think communication skills and the ability to remain objective make a bigger difference when projects become complicated? I would be interested to hear from anyone who has worked with similar experts and what qualities helped build trust and move difficult conversations in a positive direction.
