I have hired Susanne a number of times to work on documents ranging from fiction to nonfiction and academic work, and each time her work has exceeded my expectations.
She captures the nuances of the writing, she suggests changes that keep the tone and voice intact, and she manages to find all the little details that seem to slip past other editors.
One thing that impressed me was that she came in right at or before the deadline; this is something many other editors are not as careful to follow.
I cannot recommend her work enough, and I will definitely hire her again.
