All Proofreaders Seem the Same—Until You Compare Results

When one error could cost you the contract, the client, or your professional reputation, you need proof that your proofreader won't let you down. Here's what clients say after working with Proofread.co, many of them after trying other proofreaders first.

The most common wins my clients mention achieving:

01
Fast Turnaround / On-Time Delivery
So they can hit send faster.
02
Thorough, High-Quality Work
So errors they missed never make it to production.
03
Professional, Responsive Communication
So they can worry about their own work, not a response.
04
Strong Reliability / Long-Term Partnership
So they never have to hire another proofreader.
05
Detailed Proofreading and Document Polish
So their document instantly looks sharper and more professional.

Josiah did a rewrite for us that turned out to be a whole lot better than the original! Great job.

Alexander Hagerup
Cofounder and CEO, Vic.ai

Great and accurate job editing a security IT book. Not an easy topic with some challenging computer code. He understood and followed the writing “spirit” and managed to get it just right! Totally satisfied—thank you, Josiah!

Ayoub Elaassal
Cybersecurity Director, Qonto

Excellent work done very quickly. Would definitely work with him again.

Chelsea Pullano
CFO, Creatd

Christopher Hudson
President, Peachtree Publishing Services

Great work. Josiah really understands what professional level publishing means in the book world.

Cinque Hicks
Editor in Chief, ArtsATL

Josiah does an absolutely great job, with high standards, and great diplomacy about how improvements can be made. He is a bit overbooked (as he says, a victim of his own success!) so make sure that you can establish realistic deadlines. We would certainly work with him again!

Claire Harbour
Author, Disrupt Your Career

Josiah was GREAT to work with! Not only is he a meticulous editor, but he provided suggestions that I hadn't even thought about that improved the product. He was very intuitive about how to get the job done properly. Josiah also communicated with me in a timely manner, and stayed right on schedule so that the job was completed on time. I highly recommend Josiah and will definitely hire him again!

Claire Laughlin
Founder, Claire Laughlin Consulting

Josiah is a very good copy editor. There was a slight lack of communication at the beginning of the job, but once he got started he produced very quickly.

David Schroeder
Development Services Administrator, City of Ft. Worth

He was excellent at communicating quickly, and did everything I asked in the job.

Erika Boissiere
Marriage and Family Therapist

Josiah was a copy rockstar! He not only proofed the standard things (grammar, punctuation, etc.) he made recommendations for making the copy stronger. He also quickly learned the conventions of the client and was able to carry them forward. Josiah was very responsive and met all milestones as expected. I felt very confident in the work after it had been proofed by Josiah.

Genevieve Gigi
Account Lead, Looney Advertising

Great job! Fast response and helpful advice! We had a 50-page technical Offering Document that required edits. Turned the entire document around in under 24 hours. I would use Josiah again for future projects.

Gerald Kong
Principal & Senior Advisor, Trinity Transaction Advisory

Josiah is quick, responsive and very professional. Quick turnaround with great notes!

Gerald Kong
Principal & Senior Advisor, Trinity Transaction Advisory

Josiah was very responsive, efficient, and effective. I asked him to proofread a grant proposal and he finished within just a few hours with really excellent comments. His proofreading skills are great. He is direct in answering questions and providing feedback. I would definitely recommend him to anyone in need of some proofreading.

John D’Attoma
Senior Data Scientist, Internal Revenue Service

Josiah did a great job in editing the document that I had. He delivered the milestones on time and completed the project successfully. He communicated effectively and made sure I was satisfied with the job.

Kamran Akbarzadeh, PhD, PMP, DTM
CEO, Project Control Academy

Josiah was very reliable and easy to work with! I had a deadline to follow and he was great with communicating with me in a timely manner. His editing was exceptional and I will hire him again for future projects. Thank you again for all your great work!

Karina Parada
Marketing Director, Parkview Financial

Josiah is superb at what he does. He is consistently thorough, enthusiastic, patient, flexible, and communicative. When I hire him, I know I have someone partnering with me to achieve the highest quality end result. Needless to say, Josiah has become my go-to freelancer when I have a copyediting/proofing project.

Katy Conway
Senior Editor, Anywhere Real Estate

This was a slightly tricky project. The assignment required tremendous patience and collaboration on the part of the freelancer and Josiah demonstrated both. At the time he signed onto the assignment, he had not had a tremendous amount of experience with the application in which I was asking him to work. However, as always, Josiah was a quick study and jumped in and worked out the issues I asked him to address. Once again, he was a pleasure to work with and demonstrated the professionalism and attention to detail that I have come to expect in his work.

Katy Conway
Senior Editor, Anywhere Real Estate

I've worked with Josiah on several big editing projects and he always exceeds my expectations. His work is thorough and impeccable. I'll be hiring him again!

Kelly Mahler
OTD, OTR/L

Josiah edited a 47-page instructional booklet for me. He has a keen eye for detail and made excellent suggestions. He works quickly without sacrificing quality of work. I hired him for a second job as soon as this job was finished. Excellent!

Kelly Mahler
OTD, OTR/L

Josiah did a good job helping edit my manuscript. His attention to detail was very helpful in improving my prose.

Kyle Ingham
Founder, The Distilled Man

Fast and detail-oriented review of several key documents. Highly recommend this freelancer!

Marianna Bryce
Director of Marketing, Tensar

Josiah is by far one of the most highly skilled wizards of the English language I've ever worked with. He's able to edit, proof, and write all sorts of content from technical to marketing. I hesitate to give him a glowing review because he'll get so much work that he'll forget about us!

Marin Svorinic
Managing Director, Katusa Research

Josiah is very thorough and communicates well. Will certainly use him again.

Melanie Cook
Owner, VMG

I have nothing but praise for Josiah. Fast, skillful and highly professional. Will rehire soon.

Michael Kamp
Author, Cofounder, Danish Horror Society

Josiah made my proposal ten times better. I had a 2,500 word proposal due the next day. I sent him the assignment and first draft around 11 PM at night. Before 9 AM, Josiah had made great edits and had ~10 comments that caused me to materially change the proposal. For instance he found a requirement in the assignment that I had missed. Josiah not only has great editing skills, clear and crisp language but a great eye for what is needed in a business context. As an example, he told me that a section was not good and gave three suggestions for improving it. He was right! The result was a much better section. I don't know if the client will select us as the vendor but Josiah gave us a chance to be successful. I highly recommend Josiah for any business editing.

Rob Black
CEO & Founder, Fractional CISO

We asked Josiah to edit a 185-page business book about teamwork and team culture. He delivered! Josiah is an excellent editor who takes good writing and makes it exceptional. With his comments and revisions, the book came alive. After each major section of editing, he provided solid, actionable advice on the overall writing. Despite my 15+ years as a writer, I learned a few things from Josiah (or was reminded about techniques I had forgotten about). There are tons of editors on Upwork. Save yourself some time and hire this guy. You won't be disappointed.

Rob Lennon
Product Marketing & Education Lead, Hugo

Josiah was a pleasure to work with. He was propositioned with a tight deadline and worked long hours to get it done. The final product was spectacular. It now sits at #1 on Amazon, in its category. Thanks Josiah!

Ron Rivlin
Owner, Revolver Gallery

Josiah did a great job editing our investor letter. His editing skills show that he is not only optimizing for syntax and grammar but also flow and clarity of the content.

Roshan Panicker
Associate, Vanterra Capital

Great writer, precise, fluent, provided me fantastic work. Thank you Josiah!

Roy Kodshi
Founder and CMO, Personas Media

Josiah did a very thorough proofreading job on something I needed to be turned around in a rush. He caught some very important things and also added to the content. Would use him again in a heartbeat and feel very confident.

Sara Harding
Lead Organizer and Curator, TEDx

Josiah is an amazing communicator, works super fast, and very nice. I was impressed with his ability to turn around our project very quickly.

Sara Ostrovitz
Managing Director of Administration, Essential Partners

All around great work. You have a unique talent!!!! Thanks again for your excellent work and for making this task a little more fun as well!

Josiah was a pleasure to work with. He did an excellent job proofing our materials and providing thoughtful suggestions when appropriate. Hope to work together again!

Stephanie Judd
Managing Partner, Wolf & Heron

Josiah's work was thorough, on-time, and thoughtful. He delivered good work on this project and was professional and easy to work with. His review of our alumni magazine caught errors we had missed.

Stephanie Skordas

Solid work. Took project on with quick turnaround. Edits were appropriate even though I wasn't able to give him much about the target audience.

Stephen Graziani
Founder, Mastery Studio LLC

What Josiah does is awesome, an art. I wish we could design an algorithm to capture the greatness.

Taylor Ongaro
Director, Open Identity Exchange

Josiah was one of two freelancers I hired for this one job and his quality of work was notably superior. Anytime he's available and I have work I plan to hire him again.
