Just so you know I'm not making this all up, here are a few words from some clients.

"I learnt so much from having my work proofread. I feel I'm a better writer for it. Thanks!" Sandra, NZ

"...made my writing sound like a native English-speaker..." Stefanie, Switzerland

"I really feel that the value you have added is palpable." Frank, Switzerland

“We very much appreciate Karin’s attention to detail, reliability and efficiency, all the features that make a proofreader an expert. What we found particularly valuable, is the fact that Karin remains respectful to author's style yet she never hesitates to suggest indispensable changes.” Helvetiq Publishing

“Karin always completes our projects to our complete satisfaction.” HKG Consulting
