Effective Tutor for Challenging Topics
David is helping me improve my skills developing python code for Ubuntu operating systems using PyCharm. It was immediately obvious to me that his experience in these challenging work spaces is strong. Since I am effectively a novice, I was initially concerned we might have communication difficulties . However, this fear was quickly cleared as David was able to make the adjustments and explain important concepts in a clear way using terms that I could understand at my level. David establishes a comfortable and effective environment for leaning tailored to the my specific needs.

Patient and knowledgeable
We were not able to complete my needs since I am working from home. We have an appointment set for the next time I am in the office so I can fully get the information that I need.

Patient and very observant!
David helped me on my precalc homework, he helped me work on some of my weaknesses in math and helped me understand them. I bounced all my questions off him and he always had a good answer I understood. He picked up that I was a visual learner and used a graph to help me understand a chart. Thank you, David.

Knowledgeable, Quick, Experienced, and Patient. Fun to talk to.
David was able to respond on a short notice. He was extremely patient and quick in solving the issue. He answered all my questions and even knew what I was asking even before asking it. I enjoyed learning with him, seems like an awesome guy. He obviously knows his stuff and I love his honestly. He guided me in the right direction and hence I was able to do the rest of my project all on my own. David, you're awesome!
