Lisa edited my book, Committed Action. As it was my fourth book project, I've experience with a number of editors. All have been professional, but Lisa brings a lot more to her work. First of all, she LOVES editing. She loves words, grammar, style guides, the lot, and her boundless enthusiasm comes through in every interaction. Secondly, her mastery of written English is authoritative. I suspect that her earlier training as a chartered accountant (should I have capitalised the C and A, Lisa?) and her time as an auditor at KPMG has a lot to do with this - she has done the work and it shows. Thirdly, she cares deeply about her client's books. If she says your book passes grammatical and stylistic muster, you can relax. If you need an editor, you need Lisa.
