Native American Heritage - Where the Name "Teehee" Came From

The owner of the company, Deborah Hamilton, is a proud member of the Cherokee Nation who wanted to honor her beloved Grandmother Dorothy Teehee. Dorothy Teehee was a "Woman of Faith" who passed on her love and knowledge to the younger members of her family. Dorothy often educated them on the importance of protecting their culture, knowing their ancestry, and instilling the values of integrity, responsibility and reliability. Her life was an example to the younger generation and an inspiration to all that she came in contact with.
