About Chef Callie Renner
Can dinner run on autopilot—even when work runs late and kids run wilder? I believed the answer was “yes,” but I refused to guess. So I logged 4,380 kitchen hours, partnered with 200 families, and turned restaurant discipline into home-kitchen freedom. This page shows you the data, the credentials, and the story behind every Prepistry technique—so you can trust the system long before you trust the timer.

From Restaurant Rush to Real-World Rhythms
I started as a line-cook who could fillet a salmon in 48 seconds but still ate take-out at 10 p.m. Back-to-back services taught me speed, but parenthood and a shoestring budget taught me systems. When my own kitchen chaos mirrored my customers’ pain points—time shortages, picky eaters, rising food prices—I converted my chef’s notebook into field research: Could restaurant mise-en-place principles shrink weekday dinner to 30 minutes without sacrificing nutrition or flavor?
The answer became Prepistry: a data-backed framework of batch sauces, freezer mapping, and “Sunday Reset” prep sessions that real households can keep even when life isn’t Instagram-tidy.
