Joey Hajda has had a love of science since he was a boy. His initial career choice was veterinary medicine, but after receiving his veterinary degree, he discovered that he loved teaching as much as he loved science. Consequently, he got a degree in education. His teaching career has now spanned almost 25 years and has included public school, community college, and homeschooled students—including his own ten children. He and his wife, Lisa, in addition to homeschooling their children, wrote Friendly Chemistry: A Guide to Learning Basic Chemistry. They enjoy sharing their enthusiasm for science with fellow homeschoolers.
