No amount of stars can express how thankful I am for john. He went far above and beyond the call of duty and truly cares about his students. Worth every penny and then some.

Excellent mentorship, is how I would sum it. John clearly explained the reasoning and also made edits to my code, to solve my problem.

John has been an excellent mentor so far. My fear factor with setting up a LAMP server has gone from a 10 to a 5, and I feel much more capable of feeling my way through issues on my own. In addition, tweaking legacy PHP code feels a bit less intimidating, migrating servers, etc.

John Simons was awesome. As early as it was for him he took the time to help me solve my canvas issue. He did it effectively and what I consider timely. Props to him.
