Andrew Keller and Stephanie Russell both teach Classics at the Collegiate School in New York City. They are the authors of Learn to Read Latin, published by Yale University Press.
In our assessment LTRG is the best textbook for helping students to acquire high-level knowledge of Greek language, grammar, and syntax. The textbook is well-paced and proceeds logically; its abundant vocabulary notes and grammatical explanations mean that teachers and students rarely have to consult outside reference books. The workbook provides copious, well-conceived exercises, an invaluable resource for students and teachers alike, and we found its practice sentences to reflect the tendencies of Greek word choice, word order, and syntax far better than any other textbook we had used. --Ryan B.
