Hi! I'm Sandra Wissinger.

I am a proofreader and editor from South Florida. I mostly work with self-published authors in the self-help, memoir, and creative nonfiction genres. I love working on fiction just as much as I do nonfiction. I also help businesses with their content and academics with their papers.

“I’ve wanted to write a book for years. I recently invested in a program to help me do just that. When I got to the editing phase I was blessed to find Sandi. I wanted this book to be the absolute best it could be. Sandi was way more than an editor. Her guidance helped me take this book from being ‘ok’ to something I am very proud of. Her process was so valuable that I asked if she would be my guide from the start next time I want to write a book. Luckily, she said yes lol. Sandi is an absolute genius when it comes to shaping a book that both shows your genius AND speaks to a specific person. Working with her will be the best investment you can make for yourself and your future readers.”

—Ben McLellan, The Empowered CEO

“I contracted the services of Sandra Wissinger last August to proofread my new book, Marian Confirmation Companion.  Sandra was very prompt in accomplishing this large job (42,000 words) and was done in record time—we were under a very tight deadline. Sandra was very professional and in addition made practical suggestions to improve my writing. I liked her work so much I am now contracting her to translate my book into Spanish.  Thank you, Sandi! Rating: five stars!”

—Paul E. Cranley from Houston, TX

“Sandi helped me with my book Grow to Your Fullest with both copyediting and proofreading. Sandi is very dedicated and committed to delivering high quality results. As English is my second language, she took the time to correct some phrases and sentences so the stories in my book conveyed the right messages meaningfully. She was willing to take the time to talk to me so I could understand the true meaning behind some phrases. She is also very detail-oriented as a proofreader. I am highly satisfied with her service and would like to work with her in the future.

If you are looking for someone to do copyediting or proofreading for your book, I highly recommend her service.”

—Ling Qin Zhang, Grow to Your Fullest

The four stages of editing for book manuscripts are:

  1. Developmental editing

  2. Line editing

  3. Copyediting
