An author, national speaker, and an electrical engineer, Tietjen is one of the top historians in the country on scientific and technical women. She nominates women of achievement for professional and national awards. Tietjen has been inducted into the Colorado Women’s Hall of Fame.

Erik and Aicila had the privilege of conversing with Jill and learning about some of the discoveries she made over the years. We are already planning our second show with her!
