DR.THOMAS H. BROWN, JR., P.E.

The Dr. Tom Method & Strategy

Dr. Tom, as he is affectionately known, teaches the course overview lessons for Civil Engineering, outlining the Dr. Tom Method and Exam Strategy on which all DTC Reviews are based. Tom originally developed the 20-Week review format for the Mechanical PE Exams, and then, with the DTC Civil Instructors, he created the Civil PE Exam Review.

Hello, I’m Tom Brown, and I based my online 20-Week Mechanical Engineering PE Exam Review on my many years of experience preparing mechanical engineers for the PE Exam. With the help of my DTC team, I developed the tried and true structure and method that we offer online today. Our Civil and Mechanical courses will provide you will a step by step path to being successful on the exam. It requires a tremendous time commitment and effort on your part, but if you follow the plan that we have laid out for you, you will have everything you need to succeed.” – Tom Tom received his Bachelor of Science in Aerospace Engineering from Georgia Tech in 1970. He earned a Masters Degree in Engineering Mechanics from Georgia Tech in 1973. Dr. Tom holds a Ph.D. in Mechanical Engineering, earned at NC State. Today, Dr. Tom is the founder and driving force behind Dr. Tom’s Classroom where he pursues his passion of teaching engineers how to prepare for and pass the PE exam.
