Mimi Coffey Teaching
Texas DWI Authority (frequent lecturer on DWI)

Over twenty years ago as a young lawyer, Mimi was eager to learn from the top DWI lawyers in the country so she started throwing DWI seminars. Her company, Cowtown CLE, hosted for 2 years straight, the largest attended DWI seminar in the state of Texas. When the state organization for defense lawyers, the Texas Criminal Defense Lawyers Association, took notice she relinquished her seminars so that the state group could benefit. Since then, she has been speaking and course directing DWI seminars on both a state and national level for nonprofit groups to educate lawyers. See below for some of her most recent teaching moments.

Pictured above are the four course directors for the 26th annual Mastering Scientific Evidence Seminar held in April of 2019. This seminar is considered by many to be the premier scientific DWI seminar in the country. It was started by Bubba Head and held during the Master’s golf tournament each year. It was taken over by the National College of DUI Defense and is currently held in New Orleans every spring. It is co-sponsored by the Texas Criminal Defense Lawyers. Mimi has held the position of course director for well over ten years. She has fulfilled many roles at MSE beyond course directing. She has spoken on topics as varied as fermentation in blood testing to breath test issues. She has also served the roles as judge and defense lawyer in the mock trial. She enjoys bringing together technical scientific issues for the education of lawyers to better serve their clients.
