About us

About us

We've been in business since 1998, and have been selling online since 1999.

We're a small family business. Everybody who works at THE SCIENCE TeeCHER is a family member and an owner.

Our family makes its living almost entirely from online sales, and we like it that way. We believe that the key to continuing to work from home is to sell the best products we can and give the best service we can. We also take pride in doing a good job. It's just the way we were brought up.

When you order from us, your order is handled by an owner of the company. We want to keep your business, so we give your order the best service we can.

If you have a problem with your order and contact us about it, your problem is dealt with by an owner of the company. We're proud of our service, we stand behind our products, and we take it personally when something goes wrong. We don't often make mistakes or send out defective merchandise, but when it does happen, we make it right as quickly as we can, at our expense.
