Mr. D Math Was Developed Through Decades of Teaching Experience   
Mr. D Math was developed by Dennis DiNoia, who has been a Florida State Certified Secondary Mathematics Teacher since 1988. Like many math teachers, Mr. D had a side job as a math tutor, where he provided the extra guidance needed to make math finally click for students. Eventually, he realized he could help many more students understand and excel at math by bringing his strategies to an online platform. From there, Mr. D Math was developed.

Today, Mr. D Math includes courses in a variety of topics, including math, life skills, ACT/SAT test prep, grammar, American Sign Language, and more. In every course, our highly trained instructors connect educational concepts to everyday life, allowing students to apply their knowledge to the world around them outside the classroom.
 
   Our Instructors Make the Difference for Our Students    
  We are a global team of educators who deliver forward-thinking education programs that train, develop, and empower self-directed learners. We focus on multiple learning styles allowing students to discover their own strengths in how they learn.  Get to know just a few of our talented instructors below:
