About the author

Robert Coles

Author of The 28 Day Challenge series

Robert Coles has spent the last 20 years developing a career in marketing, revenue operations, sales, and brand development — and he built the 28 Day Challenge series to put that experience to work for businesses of all sizes and professionals of all levels who want real momentum, not another book on a shelf.

Portrait of Robert Coles
The career

Two decades in the work

Robert Coles has spent the last 20 years developing a career in marketing, revenue operations, sales, and brand development. Spanning over a dozen industries, he's a highly sought-after consultant working with some of the largest brands and hottest products on the market.

That range is the point. Marketing taught him how businesses reach people. Revenue operations taught him how the machine stays honest. Sales taught him what actually closes. Brand development taught him why people choose one thing over another in the first place.

The 28 Day Challenge books are written from that same cross-disciplinary vantage point — which is why every one of them pairs a focused lesson with one small action instead of leaving the idea behind as theory.

The series

Why I wrote the 28 Day Challenge series

Robert developed the 28 Day Challenge series and supporting books to help businesses of all sizes and professionals of all levels expand their reach and learn new skills. The series exists because the gap between knowing and doing is real — and a structured daily framework is the most honest bridge across it.

The method behind every book is the same one behind Robert's own consulting work: one clear objective, one focused lesson, one small action a day — because twenty-eight honest days beat a heroic weekend every time. Read the full philosophy on The 28-Day Methodology page, or browse the challenges to find the discipline your business needs most.

The collection

A lifelong entrepreneur

Robert is a lifelong entrepreneur with over a dozen brands in his collection (and growing). Building and running brands is how the challenges stay honest — every daily action in the series is something that had to work in a real business first.

Off the clock

Nashville, family, and Theodore

Robert is based in Nashville, TN and spends as much time as possible with his family, his partner, and his dog, Theodore. The same rule that powers the series applies at home: one day. Then another.
