She did an amazing job with my case. She was there for me whenever I had any questions, always a quick response. She made things organized and easy for me to understand with what I needed to do. She was very caring and understanding. And because of her help, I got full custody of my boys! Highly recommend!!

Ms. Causey helped me successfully obtain a protection order in a stalking/harassment situation that had been affecting myself and my family for several years before I decided I needed a lawyer. She was thorough, diligent, understanding, and caring throughout the whole case. She explained every step of the process and put me at ease when I started to worry. I sincerely can’t thank her enough. My whole family was immediately relieved, and we will always be grateful for her services. Definitely recommend…

I called Sierra with a question about my divorce. She was quick to respond (even called me back when she was on vacation!) Her advice was fair and direct which I really appreciate.

Sierra is a true professional. She is extremely timely, detail-oriented, well organized, and puts her clients’ needs first in every situation. She is a wealth of knowledge regarding the law and values not just representing her clients but also educating them.
