Thank you.

Dan Calvani was invaluable in helping to edit my latest chapter. Not only did he copy-edit and catch a million and one little mistakes, but more important – and I can’t stress this enough – he helped me restructure the whole of my chapter, which made it far more clear and concise. Thank you so much, Dan!

Christopher Beckman, Ph.D.

Non-fiction writer and researcher.

You did a great job! Thanks a million, Dan. Your insights and suggestions about a much twisted storyline were invaluable. Not to mention the number of narrative inconsistencies you identified, researched, and corrected. Bottom line: you made my story more than presentable, and I can’t recommend your services highly enough. Well-done, Dan!
