I've been certified in the public schools for teaching math in middle and high schools. I've taught classes and tutored also for high school chemistry and college level inorganic and organic chemistry.

Before that, I worked in the polymer industry as a chemical engineer in research and development, using my degree as a chemical engineer from the University of Virginia where I studied inorganic chemistry, organic chemistry, physical chemistry, thermodynamics, unit operation chemical labs, chemistry of integrated circuits, and polymer chemistry.

My college senior thesis was to build a computer simulated model of a packed-bed continuous chemical reactor. 

I received additional certified training for gifted and talented learners. I taught math for sixteen years and I've been a personal SAT tutor for seven years. My students have typically raised their scores between 100 and 300 points.  As a chemical engineer and project management professional in the world of business consulting and information technology consulting, I've completed over five levels of college calculus and applied mathematics and used these math and computing skills throughout my career.  

The students I have taught had varying learning abilities that ranged from one with pronounced learning disabilities to gifted and talented. When it came to PSAT's and SAT's, each of them with impressive improvements in their scores. 

It can be done!  I used a focused approach. We honed in on trouble areas, really understood the underlying math concept, and drilled for mastery.
