Onsite or online, Hallenross is the most respected name in providing sign language interpreting services.  If you are not currently a customer, check us out.  See how our highly skilled interpreters help you and your deaf or hard-of-hearing customers stay engaged better than anyone else.


Legal Interpreting

The Supreme Court of Ohio requires courts to secure sign language interpreters that hold a Special Certificate: Legal (SC:L).  If an SC:L is not available, other credentialed interpreters are acceptable.  Hallenross has more Supreme Court of Ohio Certified and Rostered interpreters available than any other provider in the state.

(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 even in the cold seat.  They represented Hallenross very well.

…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.
