We are Dennis & Mary Lou Green.
We founded Big Idea School to help you learn more about how to create and sell simple products.
Experience is a great teacher. We encourage you to use ours. That’s why we are taking you on a tour showing you some of our customers and a few of the 50 simple products we created that achieved more than $120 million total retail sales--and growing. Our experience demonstrates that you don’t have to be rich or have any special business connections to turn an idea into a product and take it to market. We also want to stress that creating and marketing simple consumer products can be a rewarding, lifelong pursuit, not a one-shot experience.

Mary Lou and Dennis in 1976
How We Started
We created our first product together in 1976, married in 1978, and built a multi-million-dollar business together. We sold our company and retired. But after a few years we missed contributing and being away from the creative flow. Now we are investing our ideas and energy into our most exciting creation of all, Big Idea School, where we are creating real-life courses to help entrepreneurs succeed.
Remember, True Wealth Isn't
All About Money
We want you to know that It is also possible for a husband and wife to work side by side in a volatile business and still be in love. In the end, isn’t love the one true wealth we all seek? Business is about creating and selling products, but even more, it is about the process of working with people you care about and achieving something you set out to accomplish. Yes, your bills need to be paid, but that doesn't mean you can't also feed your soul. Look for our book about marriage called: FIVE STAR LOVE: How to Treat Your True Love Like a Customer and Get the Marriage of Your Dreams.
