I need a catchy slogan for my bilingual services....help anyone?

Hi. I am making business cards to offer my bilingual services. I am certified in several different fields. My little slogan as of now is "Over 15 years in providing professional bilingual istance to the community". But I think that sounds stupid. I am certified in Court and in ESL, and I do interpreting for court, immigration, depositions, mediations, and in the medical field as well. I also translate doents. Can someone give me some suggestions please?
