The great staff from TALES has done the proofreading of all of my manuscripts, conference papers, proposals for research grants and presentations since 2011 and They did the proofreading of my PhD Thesis in 2015. I already published three papers with good comments about the quality of the English from the reviewers. Two more papers are in major revisions; the conference papers have always been being accepted, I got the research grant that I applied in 2013, with the support of the TALES team. They always go beyond the correction of grammar, they also make valuable recommendations to improve the coherence of the content and last but not least, they are always on time and available for short notice proof-reading and further questions. Based on my experience, I strongly recommend you the services of this company.
