Mark is the absolute best!!!

I am taking a college level Computer Science course and was very unfamiliar with anything to do with the logistics of coding. Mark was very knowledgable and patient with me and explained thoroughly each step. I am so thankful to have been able to find him as his response time is very convenient as well as planning meetings with him. If I ever need any help with anything to do with Computer Science, Mark will definitely be the person to call!!! 100/10 would recommend as any topic you don't understand or find confusing will be explained in a way that makes perfect sense!

Life changing tutor!

Mark teaches Python to my son who has had some learning challenges due to ADHD. In just a few short months he has learned more with Mark than he has in literally any class he has ever taken. My son is very inspired and will soon be taking JavaScript from Mark as well. This may well be the career path he was searching for and we owe it all to Mark. Mark is patient, fun, very knowledgeable, and effective. I highly recommend him to any student looking for a tutor!!

Patient and Knowledge Tutor

Mark helped me prepare for my Python finals. Before working with him, I was on the verge of being dropped from my major because of my low midterm scores. Mark guided me through every concept I struggled with, tested my understanding, and made sure I felt confident going into my final. Thanks to his tutoring, I ended up passing my final with an A. I’m incredibly grateful for his help.
