Our Story
Escape the City and Thrive.
Becoming a Business for Good.
Square Mile was founded by David Gormer to “escape the city” in which he built his career with Deloitte, Deutsche and Merrill Lynch.
It was David’s ambition and passion for technology that allowed him to unlock the full potential of his clients’ businesses.
We understand that accounting is more than just crunching numbers – it is essentially about relationship building through communication, problem solving, and teamwork. On top of this foundation is our goal to help our clients reach phenomenal levels of success while doing good in the world.
As a company and together with our clients, we wish to redefine how we give back. We Joined the global giving initiative B1G1. Every time Square Mile does business, the team ensures that something great happens in the world as well. Becoming a Business for Good has given us a greater sense of purpose.
