Hello, my name is Mack J. I am a cybersecurity speaker, business consultant, and author. I have a passion for cybersecurity and computer science. I have been a professor for Devry University since 2012 and have had success with my students ranging from high school to adult graduate students.

I began tutoring by helping high school students and adults in computer science and business software applications. In my consulting business, I provided training to employees using Microsoft products since 1984.

In my consulting business, I have provided corporate training programs in business law, communications, and business applications. Some of my courses included database design, accounting software, and project management.

I enjoy one-on-one tutoring with my students. I like to apply business applications to real-world situations to allow my students to fully understand the relevance and how to use their learning abilities in everyday challenges.

Please contact me with any questions you may have. I look forward to working with you in reaching your goals in computer science and business applications.
