Gail Cobb

Gail earned a B.S. in Chemical Engineering from the University of Michigan (Go Blue!). Her first job was Quality Engineer for IBM in Tucson. She then landed a position as a Research Engineer for Dowell, an oil well services company that was a division of Dow Chemical located here in Tulsa. A downturn in the oil industry led to a move to Dallas where Gail again worked as a Certified Quality Engineer. She and her team of engineers were responsible for implementing Statistical Process Control (SPC) in the manufacture of night vision equipment, and also designed and taught an SPC course to the Manufacturing department. It was a very successful and rewarding experience. Gail took a 20-year break from engineering to be a stay-at-home mom. Now that her two Holland Hall graduates are pursuing their college degrees, Gail is an empty-nester that has joined the Mathnasium team, and has found the teaching experience once again very satisfying and rewarding. Gardening is a passion of hers, along with cooking.
