David offers the following advice to the next generation of Mustangs, “You don't need to know what your "major" will be when you get to college.  But you do need to study and make the best grades possible in all of your high school courses while in high school. In your freshman year, you can start narrowing your search.”


The TJHS Alumni Association thanks David Sims for this interview and for serving as a great role model for all TJHS Mustangs.
