…the interpreters at the graduation ceremony were excellent! The deaf family members in attendance can be (and have been!) critical of interpreters, so a compliment from them is not an empty or obligatory one.

(Hallenross interpreters) were EXCELLENT in every way yesterday at the advisory committee meeting. They had beautiful language. They were so professional. They were dressed professionally, they were attentive. (...) They represented Hallenross very well.

She's great and she made sure I knew everything that everyone was saying not only to me but also let me know what was discussed between everyone involved in the meeting I definitely recommend her to anyone.
