Why do I coach?

When I was pivoting out of academia, I did not have many opportunities to meet people who had followed a similar path. This forced me to try and navigate that uncertain road mostly by myself. I coach because I want to be the person I wish I could have met when I was first deciding to pursue a job in industry.
