Dependable, seamless, thoughtful, the best!
Leon is the best! I can not say enough about his organization, efficiency and human touch. I have never filed for bankruptcy before and didnt know what to expect but I was worried. Leon made me feel comfortable, knowledgeable and confident throughout the whole process. He was always there and always on time and dependable. He really made me feel human and made the whole experience really a joy if that's possible! He made this whole experience as enjoyable as I believe you can make it. I have such gratitude for Leon and team that I felt compelled to write him a review to hopefully help other people to enlist his services. You will be glad you did!!! Thank you Leon!!!!!!

A great help when I was in need
At a time that is full of uncertainty and stress, Leon was a much needed breath of fresh air. I was very wary and frightened about filing for bankruptcy, but Leon's compassionate, accessible, and patient counsel truly set me at ease. I cannot thank him enough for carefully guiding me through this challenging time. If you are in need of filing, or even considering bankruptcy, I highly recommend Leon Bonney.

Excellent, courteous, thoughtful
I interviewed several BK attorneys prior to engaging Mr. Boney for my Chapter 13 BK. He had done research on me and my work as a professional musician and I was very glad that he had acquainted himself with both me and my business. He answered questions whenever I had them. He was thorough, thoughtful and came up with a plan that is allowing a fresh start. I cannot thank him enough.

Very Satisfied!
I went to Leon at a desperate time when I did not know which way to turn. He was not only professional, but really cared about my best interest. He walked me through all the steps, was a great advocate on my behalf, and continued to assist me throughout my ordeal. In difficult vulnerable times you really want to have someone you trust on your side. I would not hesitate to go to Leon again if needed.

Legal Advice with a face
I'm a small business owner (travel agency) owner who needed advice regarding entering a joint partnership with another agency but still retain whole ownership of my original business. It wasn't a normal legal consultation where I felt the guy racking up the billable hours in his head while I was talking, Attorney Bonney was a real person giving me real advice. If you need professional legal service with years of corporate experience behind it, he's your guy!
