who builds it
Brian Perkins builds these.

One person, with his name on it.
Twenty years spent in the lab working with cardiac device patients, where a system that almost works is not acceptable. I build these one business at a time and I answer my own email.

Rigor you can audit, craft you can feel. The name is two grandfathers.
Franz Berlacher was the head: chief of cardiology, Notre Dame football, one of the youngest graduates the University of Chicago’s medical school ever produced. He brought modern cardiology to Northwest Ohio.
Floyd Perkins was the hands: an eighth-grade education, forty years at the Champion Spark Plug factory where he met Margaret, seventy years married to her. He taught himself fine art and painted every day.
They were friends, both men of principle, and their grandson spent twenty years putting cardiac devices into the region Franz built, learning that the best work is both things at once. That’s the standard here, and it’s why the name is theirs.
