First and foremost - I AM A REAL PERSON. I get this question all of the time from people who confuse me with a big brand or company or from people who don't believe children they know have had me as their teacher.
I am a sixth grade U.S. history teacher in Northern Virginia, who happens to double as the founder of this site. Because I love doing both so much, I never could choose one over the other and as such I have two very fulfilling, yet very demanding full-time jobs. As far as MrNussbaum and MrN 365 go, I am a one-person show who dreams up all that you see on the site. That said, I was never particularly effective as a coder or artist, so after I dream up the ideas for games or complex activities I have a team of talented designers and programmers whom I pay to bring my ideas into digital reality.
I currently teach in a gifted and talented center, but have taught second, third, fourth, fifth, and sixth grades. Most of my time not spent in the classroom is spent building or editing this site, hanging with my two boys, or, playing sports, getting outside, or visiting historical sites.
I sometimes hire my former students (now in college or beyond) to help me in creating content for MrNussbaum.com and MrN365.com
Yes, this is my real last name. It's much more common than you might think, actually. It means "nut tree" in German, which fits me really well. My students call "Mr. N". If I could start mrnussbaum.com from scratch, I'd definitely called it mrnuttree.com
