    “Very nice demeanor and easy to work with. Very patient with my lack of knowledge about programming. Made sure he completely understood what I needed before beginning -- I really appreciated that. Provided me with a really good idea for making website more easily navigable, even though that wasn't in the job description. Worked on the project steadily until finished. Finished in a timely manner. I would not hesitate to use his services again. Thanks!”
