‘During the legal advice process, the most important thing for clients is case law and analogous precedents, and if they are not available, strategies to address them. Despite this, most law firms often only approach and offer opinions from a theoretical perspective. Yoon & Yang LLC offers a realistic alternative for companies to consider, and it's a good solution.’

Also, they are skilled in presenting precise, multidisciplinary arguments to the court. They have been very helpful in solving our company’s complicated legal issues and bringing successful outcomes.’
