I've used LinguaOne at my workplace. It's a great interpretation company and their staff are very friendly and patient as the calls they are interpeting can get kind of long. Highly Recommend!!!

Interpretation is the transfer of speech from one language to another, whereas translation is the conversion of written text between two languages.

A professional interpreter is trained to meaningfully transfer speech from one language to another while applying techniques in real time to account for faster speech or unknown terms being used by the speaker.

Medical interpreters traditionally assist hospitals, clinics, or doctor’s offices by interpreting between patients and staff in various situations including, women in labor, emergency surgeries, day surgeries, and dental visits. 

Our on-call medical interpreters are asked to be at the hospital in 30 minutes or less after being requested. 

Meanwhile, hospital staff can connect in seconds with a video remote interpreter or telephonic interpreter until the on-call interpreter arrives.
