Mark My Words Editing

Professional Editing & 
Proofreading Services.



I offer all three of the main types of literary editing:

  • Proofreading,

  • Copy Editing, and

  • Line Editing

Directly below this section (and above in the menu at the top of my page), you will find the links to my pages that explain the differences in those services, my pricing, and how it all works. Please feel free to look through those links, and don't hesitate to reach out with any questions.




Welcome to my website! My name is Deidre Sequeira, and I am the owner of Mark My Words Editing.


Mark My Words Editing is an editing and proofreading service for writers of all sorts. Whether you're an author, a student, a screenwriter, or anyone else putting pen to paper (or fingers to keyboard), I am here for all your editing needs! 


I am a lover of all things words. I'm an author, and ELAR teacher, an avid reader, and an editor. I have my BA in English with a Concentration in Teaching and two Associate's degrees: an AA in English and an AA in Liberal Arts. I use the skills I've acquired through my schooling and my personal experiences in the indie publishing industry to ensure that you're happy with your work and are ready to hit "publish" by the time I'm done with it.

A list of my past work is available here, and a list of FAQs is here.

Feel free to take a look around, and please don't hesitate to contact me with any questions.


Thanks for stopping by!

Rising from the Ashes - Lea Moreno Santana
"Deidre helped me edit my book, Rising from the Ashes. It was a very tedious process, but was completed in a timely manner and the final product was exactly what I had envisioned for the book. Her accuracy and dedication to Rising was impeccable, and I trust her with any of my other works, now and in the future."

The Order 
- Ryder Lyne, Dystopian Author
"Having worked with other editors in the past has been an absolute headache until finding Deidre. She is my go-to editor on all of my projects and the editor I refer to my ghost contracted clients. Deidre's created a seamless process in her craft and respects my voice as an author while creating a flow that is understandable to readers. The common misconception is that editing is where the hard part begins, but I can honestly say I don't have any headaches or doubts when I get to that part of the process having complete faith in working with her. She's efficient, time-sensitive, and thorough to a degree that far exceeds previous editors I've had tackle other projects in the past."



I'm looking forward to hearing from you!
