Posted by anonymous | February 20, 2023 | Hired Attorney | Domestic Violence

Case dismissed

Roger, thank you for helping me with my domestic violence case. First, I was facing jail time and thought my life and career were over, but the positive relationships you have established with the San Bernardino County district attorneys office and the fact you didn’t give up on my case, got me the b...est outcome and never thought the charges would get dismissed. You are very professional, always available and again thank you for everything you have done for myself and my family.

Relationship: Fellow lawyer in community

"Roger and I started law school at the same time and he has always been a good and dependable friend. As an Attorney, those same qualities have translated over to his practice and ultimately led to his success. Whenever I have a criminal matter in front of me I feel confident sending it over to Roger as he is an excellent Attorney with decades of law enforcement experience."

DUI and DWI lawyer | Oct 13

Relationship: Opposing Counsel on matter

"I first met Mr. Chien in a trial as opposing counsel. We of course exchanged pleasantries prior to entering the court room but I was unfamiliar with him as I am based In Bakersfield. Although we had just met, he extended me the utmost respect while zealously representing his client, a sometimes forgotten trait among attorneys. Since then, I have assisted him in a few criminal cases in Kern County and have learned that he provides representation in domestic violence cases. He has always been very professional in our interactions and he is very knowledgeable in the fields of criminal law, domestic violence, and collections. I highly recommend Mr. Chien to anyone seeking legal representation."

Personal injury lawyer | Nov 15

Relationship: Friend

"My office needed a special appearance attorney for a mediation in Downtown L.A. Two days before the scheduled mediation, the special appearance attorney agency said they could not find an attorney available in LA. I immediately thought of Mr. Chien, whom I went to law school with and kept in touch. I reached out to him with the assignment. He got back to me within the hour and accepted the assignment. He showed up to the mediation approximately 15 minutes early and completed the assignment for us. He saved my office a lot of time and hassle to go to LA from San Diego for a matter that lasted less than half an hour. I endorse this lawyer."
