About Elephruit

Mike Zehrer

Resident Nerd

I've spent my career walking into ACA and Medicare Advantage businesses that were bleeding tens, and sometimes hundreds, of millions of dollars and helping turn them around. The trick isn't magic. It's letting the data decide what matters instead of doing things because "that's how we've always done it."

Before health insurance, I was a paramedic and nurse, where you learn quickly that bad assumptions have consequences. That mindset never left.

I use AI every day, but not to generate corporate word salad. I use it to tear through massive datasets, spot patterns humans miss, challenge my own assumptions, and find the stories hiding in the data.

I have opinions. I'll back them up. If I'm wrong, I'll say so. If the industry is being ridiculous, I'll probably say that too.
