“My experience working with Sean as an editor was seamless. At all times, he was very professional and prompt.  However, what stands out most of all was that he offered a very educational and informative perspective, as all of his suggestions came with explanation. Working with him was easy due to his open-mindedness.  I would recommend writers to work with Mr. Dennis no matter what the content area because this kind of editor is difficult to find.”

“I’ve written two books. The first was without Sean’s editorial help and wasn’t great (check the reviews). The second was with his help and turned out much better on all fronts. I’d believe these facts weren’t related if I didn’t enjoy working with Sean, appreciate his great feedback, or appreciate his wisdom for an inexperienced technical writer like me. Hope to work with him again in the future!”

66″Sean was my excellent development editor for Manning Publication’s Learn Git in a Month of Lunches. He was inserted into the book’s development mid-stream, taking over from a transitioning editor. He handled this turnover with ease, getting up to speed quickly and diligently. Sean provided steady, constructive feedback as he oversaw a revamp of my table of contents and the delivery of several chapters. His guidance made the book clearer. He was terrific at managing not just my expectations but also the publisher’s, and I was grateful for his work on the book. I highly recommend him as an editor!”
