CUSTOMER FEEDBACK
Fion
"Our event was a big success. The interpretation received great recognition from both the executives of our company and our clients. Fion did great jobs in media roundtable and workshop tasks."
Danni
"I thought Danni was great - 5. Would definitely
recommend using her in the future.
Danni was very good, TravelSky CEO really appreciated her efforts."
Fion
"The feedback for Fion from HMG was excellent. She was extremely professional, the translations to the slides went down very well with the delegation. And she responded to complicated and technical language very well."
Danni
"There are a lot of positive feedback about her interpreting for a leading financial institute. The comment was Danni was much better than the ones the audience normally experience."
Fion
"Fion is very professional and she seems to manage to translate even the most complex scientific information without batting an eyelid. I also know she was recovering from a cold but she didn’t allow that to interfere with her job. She’s a delight to have in the party and yet she’s always watching for the moment when she needs to translate even in a social environment. I can’t speak too highly of her."
