Thank you so much for your prompt and professional service. Dona Le really listened to everything I wanted. She was meticulous when editing my manuscript. Dona Le is obviously a very talented editor.

“I am working on my dissertation for my doctorate and was in desperate need of an editor for my chapter 1. I submitted my paper for a two editor review. To have the perspectives of both editors was priceless. They reviewed my first chapter of my dissertation and sent it to me within a couple of days. Words can not express how pleased I am with the feedback. I have saved at least a couple of months with their review and editing which allows me to move forward with chapter two. I can say with my remaining four chapters that I will be back. Thank you Jane and Erick, and thank you Sibia Proofreading!”

The standard delivery option provides for a 72-hour turnaround time and, despite having submitted my request at 9PM on a Wednesday, I received my meticulously and thoroughly edited paper back at around 6AM that Saturday. Thanks so much for your help!”

Martine  08-Oct-2014
“I had my disseration proposal edited by Sibia. Because of the document's length, Sibia was able to provide a price lower than the published prices, and they returned the paper a full day earlier than promised.

Melissa B  07-Dec-2008
“When first I submitted my document to SibiaProofreading.com, I was not sure if they could work on it properly and efficiently because the subject of my document was unfamiliar as well as complex to many.

Michael Schlosser,  University of Illinois Police Training Institute 18-Mar-2013
“I can only thank Sibia for their excellent service and recommend them to everybody looking for a professional proofreading of their manuscripts. As a non-native speaker, I had my dissertation proofread and edited by Chris. All in all, he has done an amazing job. Ranging from minor (punctuation) to larger (rephrasing of sentences) changes, his immense amount of suggestions (about 10 per page on average) have improved both the quality and readability of my thesis, while preserving my style of writing and better conveying its message. What more could one expect?”

“I would like to share my experience with Sibia. I must admit initially I was skeptical; however, after submitting two of my papers and getting phenomenal feedback, I am preparing to submit another much larger paper. The price per page is comfortable in comparison to other sites. This was a great experience!! Thanks to both Joanna and Marc.”

“First I'd like to say how refreshing it is to have a copy editor that is punctual. I won't go into detail on how many times I've been put off by editors that take on more than they can handle, but Dona delivered on time and that scores a high mark in my book. Secondly, I am pleased with the thorough process of not only editing for grammar and punctuation, but for content and clarity. It took me a few years to write this novel and there were some redundant elements that Dona pointed out that greatly helped the flow of this story. I have already recommended this company to other writers and will continue to do so. Great job!”

“When I summited my 84,000 word true crime novel I was scared and filled with self-doubt. I worried that the editors would see my work as rudimentary and grammatical torture. Surely my edit would be filled with red lines and horrific comments, but to my surprise, Joanna and Dona were gentle with me. I felt an immediate kinship with Joanna. She was a jewel to work with. Joanna made suggestions that made perfect sense and she played an important role in making sure the novel had a good flow and packed the punch that I desired. I am so thankful for her assistance and I now feel confident about my work. I can never truly thank her enough.”
