And of course, there’s the Black Diamond Group itself.

PResident and founder

Seth Diamond

As an entrepreneur via the Black Diamond Group LLC, Seth has founded and run many small businesses over the years. By marrying his love of graphic design, music, video (and even culinary!) with cutting edge IT, Seth connects left-brained visual communications and art to right-brained tech.

Many people are taught to build their careers linearly. They go to school, they learn a skill, and attempt to become an expert in a single field or two.

Career-wise, Seth has never been linear. 

And he wouldn’t have it any other way.

Voluntarily defecting from his third-year clerkships in medical school back in the ’90s, Seth realized that his happiness could be found instead in an interdisciplinary career, where he could constantly channel his creative energy. Plus, he was never content to just wear one hat and always wanted to run his own show.

By founding and running various small businesses over the years, Seth continues to express his art through various multimedia ventures, while also contracting with businesses on various IT and multimedia projects that support fellow creatives. 

If all this weren’t enough, in the middle of all this, Seth trained to become a chef at Le Cordon Bleu Boston and passed the Court of Master Sommeliers’ Introductory Exam, which led to the creation and ongoing production of Food Biker. After all, creative in the culinary and beverage worlds both encompass both the senses of taste and smell.

So, yes. There are a lot of experts out there in both creative and IT.

Meanwhile, you’d be hard pressed to find someone who deeply understands creative that truly appeals to all five senses, the IT and tech to showcase it all, and the entrepreneurship required bring it all together.
