About

My name is Mark Detre. I've spent over 15 years helping businesses protect and strengthen their reputations during the moments that matter most.

My career has taken me from Google and Vodafone to leading communications for high-growth tech companies, working across multiple countries and industries. I've advised boards, managed crises, shaped government policy, and built communications functions from the ground up.

Experience where it counts

I've handled the situations that keep founders awake at night. A warehouse fire destroying hundreds of customers' belongings. 5G conspiracy theories threatening operations during a pandemic. Wage underpayment scandals requiring complete reputation repair. Sensitive leadership transitions under media scrutiny.

Most recently, I led communications for two companies in the telecoms sector, where I positioned both companies as credible industry voices. I've secured Prime Ministerial visits, shaped public policy, and turned potentially damaging situations into opportunities to demonstrate leadership.

Why I started Northbrook Advisory

Through all of this work, I noticed a pattern: growing businesses often face their first major reputational challenge without the right support in place.

That's why I founded Northbrook Advisory. I work with business founders as their crisis PR advisor. I get to know your company before problems emerge, so when they do, you have clear-headed expertise ready to act immediately.
