Client's Testimonial

  "We had a previous estate planning attorney who had drafted a few limited documents/plans a few years back that went obsolete pretty quickly as not much thoughts went in there.  We were always confused by the seemingly complicated processes, but recently decided to find an another firm who can truly lead us through clearly this time.  We came to Attorney Ke and her team through recommendation by a friend. From the initial consultation, to the detailed planning and education, till the end of documentation and execution, the service was amazing, and we came out fully prepared for what our family needs. The personal touch, patience and professionalism summarize our experience with Lion’s law. Highly recommended!"

"Having a professional and reliable lawyer in a non-native language country is extremely important. In addition, our requirements were not well organized.  Attorney Ke is a good listener, and you are able to feel comfortable speaking to her about private statuses. Also she has ability for explaining things clearly to a layperson, and she will be patient with your reflecting on your needs and desires for your estate..

She communicated with us via email, phone, and also can work remotely. She set a visual meeting 
up for us with of counsel well-known local in the field as well. She was patient with our questions, 
and also works efficiently and will deliver a fine finished product in a short period of time. She also follows our personal processes up as well. So, I believe, whatever for Wills, Health Care Proxies and Powers of Attorney, or any others, if you choose Attorney Ke to represent you in your estate planning, you will be very lucky what you did."
