At home

Beyond his thirst for learning and passion for helping people bring more trust into their lives (the confidence for self-trust, the courage to trust others, and the combined competence and character to earn others’ trust), David is a keen fisherman, home cook and wine enthusiast, and former singer and guitarist in The Black Knights who still enjoys bashing out some chords and a singalong with family and friends.
