Amazing and Knowledgeable Tutor

Gregory stepped in last-minute and helped my son who was struggling with his Matrices and Concepts of Mathematics classes. He was thorough and patient. Working with proofs is not my son's strong suit, so Gregory helped him connect the dots. We highly recommend Gregory, and we will use him again.

I highly recommend Greg for tutoring. I have used him for help with several different college-level mechanical engineering courses, and he has been great for all of them. He is easy to work with, and all of our sessions have been extremely helpful.

Stays at your pace without frustration

Gary was helpful in finding different ways to approach the subject matter. Only had a single lesson but was generally pleased with the session. Gary is a very kind and patient tutor.

Great Tutor

Helped me deepen my understanding of specific concepts and problems for E&M physics. I like that he asked me questions about my own thought process rather than just doing the problems for me; his explanations were clear and helpful with a step by step process.

MATLAB Tutoring

Gregory was very helpful in assisting me with my MATLAB code for a course project with little notice and helped me identify the proper process for creating a multi-attribute utility function and matrix. Using his knowledge and tips, I was able to successfully mend my code and create the necessary functions for my paper. Thank you, Gregory!
