What are Kolkulations

I juggle lots of numbers to squeeze stories out of them that help people understand their world by measuring and quantify things quickly for them. My college training began with part time work at Foremost Insurance. Upon graduation that actuarial internship help me land my first actuarial job at The Hartford. During nine years there an underwriter Margaret got to know me well. Knowing me and my last name, one day she said “Steve you do very nice calculations. You do Kolkulations.” That’s how the name of my business came to be:
