Without hesitation I can say that Ms. Ko is the most talented Korean interpreter and translator that I have had the pleasure to retain. Intellectual property litigation is often fraught with extremely technical terminology that generally presents issues for foreign interpreters and translators. Ms. Ko’s vast vocabulary and familiarity with technical terminology have consistently permitted her to excel with precision and accuracy in interpretation and translation. As a result of her friendly demeanor and great personality, working with Ms. Ko is also a pleasure. In short, Ms. Ko has a proven track record in highly technical litigations and she is always my first choice.

Don’t think twice when considering the right interpreter and translator for your complex case involving the Korean language,hire Soomi Ko. In my product liability matter involving tens of millions of alleged damages, the parties jointly retained Ms. Ko. The case involved the complex science of polymer engineering and failure analysis, but Ms. Ko quickly managed the technical terms and industry jargon, and was able to clearly and accurately translate hundreds of hours of deposition testimony to the satisfaction of a room full of Korean speakers from both sides. Ms. Ko also translated hundreds of pages of technical documents for both sides, on a demanding timeline.

Todd Rosencrans, Perkins Coie LLP

Ms. Ko is highly skilled, extremely hard working, knowledgeable, and personable. She interpreted effectively for us in six straight days of depositions in Seoul in a highly technical federal court case that demanded the utmost concentration and accuracy. Several of the deposition sessions—which were video taped without a court reporter pursuant to FRCP 30(b)(3)(A)—lasted ten hours or more. Because there was no stenographic reporter present, Ms. Ko had no transcript that she could refer to as the depositions proceeded. The questions and answers were often lengthy and complex. Ms. Ko’s skill, patience and good humor with the witnesses (and lawyers) was remarkable.

Hall Baetz Partner at BaetzLamka LLP

Hands down, Soomi is the best Korean interpreter around. There are no other interpreters I know who can handle Korean-speaking witnesses at trial like Soomi.

Ekwan Rhow, Partner at Bird, Marella, Boxer & Wolpert

Ms. Ko is simply the best Korean interpreter available in Southern California, no matter the context. She has interpreted numerous depositions for me both taking and defending depositions. Her skill and experience, her command of legal and business terms and her cultural sensitivity (especially to business executives) makes her particularly valuable in preparing clients for testimony and counseling them during legal proceedings.

That is why we have used your services for the last few years…faultless, accurate, fast, and sensible translation…all given with a most pleasant smile as well. Thanks again.

Professor Robert S. Spich Faculty Program Director, International Management Seminars, UCLA CIBER

I had the opportunity to spend a full day teaching executives from Beijing Television Network at UCLA. Lingling was the interpreter. To say that I was awed by her skills as an interpreter is an understatement. Lingling understood all the nuances of what I was trying to communicate and by the questions coming back at me from the executives I knew my words were being completely understood, even my sense of humor! Beyond her skill as an interpreter, Lingling brought a level of commitment which added to my credibility. By that I mean she helped me shape some of my thoughts so the audience could Continue Reading
