About Common Practice

Great conversations inspire, connect, and heal. Our mission is to design the practical tools that make these conversations accessible to everyone. Too often, conversations about what matters most to us are avoided – in healthcare, but also in our daily lives. Working with our partners and customers, we make great conversations common practice.

Applying his background in human factors engineering and design, Nick has been creating innovative social interventions for over 20 years.

His work is informed by his ongoing study of Gandhian nonviolent methods and social movements.
