Brian Miller
Founder, President & CEO
Brian is a builder at heart, both in business and in life. As the leader of NNI Construction, he’s had the privilege of helping brands scale nationwide, completing more than 400 fitness facilities across the country and 200 more retail and commercial projects. His philosophy has always been simple: combine national vision with local precision. That balance allows him and his team to deliver projects that not only meet brand standards but also make a positive impact in the communities we serve.
But beyond the hard hats and job sites, Brian’s greatest pride is his family. He’s a father or 3 and everything he does in business is rooted in the values he carries at home — commitment, trust, and building a foundation for the future. Brian’s family keeps him grounded, gives him perspective, and reminds him why it matters to do things the right way.
Today, Brian is not just focused on construction. He’s also passionate about innovation — creating digital tools to make project management smarter, more efficient, and more connected. It’s about scaling together, whether with his team, his clients, or his family, and building something that lasts.
