Our Passion and Purpose

I have always been fascinated with the tension between what the numbers say and what humans feel. The numbers have less variability yet it’s incomplete to say that we should only look to numbers for answers. In high-stakes decisions, this duality matters. Systems and structure are needed but love and care for people matters just as much.

This is why I do this work; because in the end, the purpose of the systems and structure is to facilitate our love and care for people. And in high-stakes situations, getting it right is all the more important.
