Letter from the Founder / CEO:

I never thought I’d get into the underwear industry – but somehow, I got involved in an underwear start-up called Freshpair back in 2001 which became my passion for the next 10 years. Other than wearing it (and previously boxers I’m ashamed to admit), I knew nothing about this category. I just had an interest in technology and marketing, and knew how to solve problems and have fun doing it. Over the next 10 years, I built an underwear empire and a reputation, thus opening up my eyes to an exciting industry. I’ve created women’s and men’s underwear runway shows in Times Square, advised the most well-known underwear companies, made numerous TV appearances, and influenced an industry that I have come to love. Since men’s underwear is where my passion lies – after deciding to build something new, I started The Underwear Expert, to solely focus on the men’s side of the underwear business and share my underwear passion with the world. The Underwear Expert Club is one of a kind, using the expertise of a incredible team, my history in the industry, and a custom technology solution designed by me, specifically for a curated underwear business.

And yes, I’ve graduated from boxers to briefs.
