As editor of two trade magazines, "Business Fleet" and "F&I Management and Technology" in the early 2000s, I found Debbie Salter's copy editing to be accurate, valuable and reliable.
I can highly recommend her work without reservation.
Jay edited a business letter for me. His revisions sounded much more human/personal than my original and emphasized how my audience would benefit from my services. I highly recommend Jay as an editor and writer.
