How Jim is building a better working world

“By supporting EY clients to mitigate cyber threats to critical infrastructure assets, I’m helping build a better working world — one where organizations can bring their goods and services to market in a safe and sustainable manner.  

I’m also a strong believer that the best way to build a better working world is by investing in youth and helping them achieve higher education. I’m honored that my wife and I are able to do this through scholarship donations to the Houston Livestock Show and Rodeo and philanthropic commitments to The University of Houston.”
