great teacher!

Larry is a great professor! He has been teaching me for the last year and I will be having more classes with him. Thanks to him I understand much better how Java works and I got really good grades on my assignments and projects. He is really patient and knowledgeable. Thank you Larry for your help 😊

Rosa, 13 lessons with Larry

Excellent tutor

Larry is a patient and very knowledgeable tutor. My son was struggling badly in Math, and was not able to get the appropriate help at school, so we sought a private tutor for him. When schools closed because of Covid 19, we continued on via online lessons, and Larry was able to help him not only with Math, but Computer Science as well. My son went from a F in Math last semester to finishing the year with a B. We could not be more pleased with and thankful for Larry's help. especially with the challenges of this school year.

Karen, 9 lessons with Larry

Extremely knowledgeable and patient

Larry was an excellent tutor. I was having some trouble with my final project in COBOL. He walked me through a good portion of the project where I was having issues and explained it in a way that I could easily understand. Absolutely recommend to anyone that have questions in COBOL.

Knowledge and effective tutor

Larry taught me about the syntax of void functions and how to manipulate them to accomplish a specific task. In addition, i learned about recursive functions thanks to Larry's guidance.

Great Tutor!!

I learned SQL triggers in just minutes with Larry, He did a much better job than my professor. He also taught me about sequences as well. A+ will definitely contact him again in the future for any SQL related help. 👍🏼

Knowledgeable and patient tutor

Larry really knows SQL (concepts and how to use queries to solve exercises and problems) and he is able to explain concepts easily! Larry helped break problems down into step by step processes. Thank you, Larry!

Jenny, 2 lessons with Larry

So nice and patient

He helped me through a java problem and some basic concepts in java that we didn’t get a good briefing on in class. So nice and patient throughout the process even though I was being dense. Really appreciated.
