Client Testimonies

 "We enlisted the assistance of Wong & Associates in connection with the early termination of a commercial lease several months ago and the matter was handled thoughtfully and diligently by one of the attorneys, Edward Hung"
          -- J S. 

"Nicholas Yang was a pleasure working with. Him and Dorothy both assisted us during our real estate mediation and helped my parents get their house back. My parents are both Chinese immigrants, speak little English and have never been sued before. The process of getting sued was really scary to them, but Nicholas and Dorothy were both able to empathize with my family. Their work is professional and diligent. I am glad my family worked with Wong, Chang & Yang."

-- Shirley C.

   " 我是2017年9月开始启用Vance Chang做为我的家庭法律师代表。2019年1月我的案件结束。我对Vance的专业知识、人格品质、认真负责的程度高度认可。
而Vance很专业、理智、客观的分析案件。收费合理。他会帮助你在混乱中找出问题的要点,把问题简单化,还会帮助你疏导心理状况。而且Vance可以说中英文双语,开始他说他的中文不好,后来我发现他说的很不错。前台的助理告诉我,Vance做事情总是很谦虚。是的!在上庭前,Vance做了很多的功课,我看着他拿着很多他整理的文件,这让我信心大增。在庭上也会极力帮助你辩护,随机应变能力强。我最终对这个案件处理结果非常满意。直到今天才来写这个评论,总是不能用语言来表达感谢!我高度推荐Vance Chang和他的律师事务所。 "

English Translation:

"I hired Vance Chang as my family lawyer representative in September 2017. My case ended in January 2019. I highly value Vance's expertise, personality, and responsibility. Before that, I changed a few lawyers, and I have consulted a lot of lawyers. I believe my judgment in lawyers. Some lawyers will pick things up in the middle and get more income from them; some have problems with professional level; there are few things to do, when you receive the bill, you will be dumbfounded with high Attorney fees. So I am not trusting lawyers. Vance is very professional, rational and objective in analyzing cases. The charge is reasonable. He will help you identify the main points of the problem in the confusion, simplify the problem, and help you to ease your mental state. Vance is bilingual and can speak both Chinese and English. He said that his Chinese is not good. Later I found out that his Chinese is very good. The assistant at the front desk told me that Vance is always very modest in doing things. Yes! Before going to court, Vance did a lot of homework. I watched him carry a lot of documents he had organized, which made me more confident. In the court, he will try his best to help defend you. I am very satisfied with the outcome of this case. I haven’t come to write this comment until today, and I can’t express my gratitude in words! I highly recommend Vance Chang and his law firm."
