Duluth isn't simply a great place to spend your vacation, it's a great place to spend your life. Nationally ranked as one of the best and most affordable places to live in America, our wonderful little city is also one of the top places to work. We're home to Soft Center, a European-based business concept that unites technology businesses, educational institutions and government agencies, helping them grow together. We're also home to flourishing aviation companies like Cirrus Aviation, plus manufacturing and health care industries, not to mention some of the hardest working people in the world. Beyond that, our schools, cultural opportunities, laid-back way of life and tremendous natural surroundings make Duluth too much for just one trip - you'll just have to come back and stay a while.
