ABOUT US
About Dr. Lanny J. Acosta Sr

Hi, I’m Dr. Lanny J. Acosta Sr. Born in the bayou country of Southeastern Louisiana, my journey from working on the Saturn project in aerospace to becoming a teacher, principal, school superintendent and ACT prep expert spans over four decades. I’ve been passionate about helping students succeed since 1980, using creative and innovative teaching methods to prepare them for life-changing exams.
With a commitment to teaching the fundamentals of English, Mathematics, Chemistry, Biology and Physics, I know that new knowledge is the basis for understanding challenging questions and the logical thought needed to answer correctly. What you know changes what you see, and what you see enables you to think.
Tiffany Acosta Brennan, a graduate of Spring Hill College, goes above and beyond to ensure the success of her students. Tiffany is an experienced high school and elementary school teacher who strongly believes in teaching the fundamentals of math and reading. For 25 years she has been motivating students in preparing for college entrance exams as well as positively affecting the lives of the students in her classroom.
