Recent ODU college grad and NASA Engineer with 5 years experience offering math, science, and engineering tutoring services. Can come to you or meet at a location. Flexible times. Good rates. Working

Methodology

My methodology is to first identify the level of understanding the student has for the given subject matter, then engage with the student through instruction and problem solving. My approach of problem solving, is to help the student understand the process/concept instead of the answer. This allows the student to retain the information based upon application instead of lecturing.

Background

I am a mechanical engineering graduate (masters) from Old Dominion University. In combining a rigorous academic experience with professional roles in the public and private sector, I have exemplified my keen ability to troubleshoot difficult engineering problems, collaborate on teams, and utilize resources at an expert level. Recognized for improving engineering and operational optimization, I have a verifiable history of professional success as both an intern, student, and worker. I have tutored college students students in chemistry as an undergrad, and have tutored students of various levels of math from algebra to calculus before my career at NASA. I have also tutored college/highschool physics from time to time for some of my colleague's kids.
