Meet Christy: Impact drives everything I do.

I am a “real idealist". That shows up for me idealistically in that I believe everyone wants to do better and take steps to do so. The realist in me understands that the path to make positive change takes work, time, and people can be resistant to that progress for various reasons.

Those two views, idealism and realism, are often said to be opposing forces. However, I like to think of them as guardrails for the work that people in organizations want to do. 

My role is to understand the real opportunities and struggles organizations face on the path to drive greater impact and I design programs to eliminate or reduce those issues so progress can happen. 

Approaching complex environmental, social, and governance (ESG) issues with that lens builds trust that often makes businesses more sustainable over time and their actions more impactful.

I joined the 4xi team to expand my impact and simplify sustainability for greater adoption. There are no boundaries with this talented team working together. You might have a simple program that needs developing or a complex ESG Strategy. No matter the task, our strength is in the collective. 

Welcome to the 4xi team:

Our Strength is in the Power of Our Collective.
