I have attempted to contact Brian Mullen multiple times via phone and email after having invested close to $30,000 in his services. Unfortunately, he has not returned my calls or responded to my messages. I have several important questions regarding false accusations in my case that are currently in the appeal court, and he is my attorney in my case to address these concerns. I would appreciate any assistance in reaching him or guidance on how to proceed.

The gentleman who recommended Mr. Brian Mullen to me shared how Mr. Mullen successfully resolved his case expeditiously. According to his feedback, Mr. Mullen found simplified and effective ways to reach a good resolution for his matter, which meant minimal legal fees to this individual. This feedback spoke volumes to me. Like many, I was concerned about the cost of representation and finding a trustworthy lawyer. I am so happy that Mr. Mullen lived up to the expectations I had, which was a good lawyer with honest fees. From the initial meeting, Mr. Mullen was an unmitigated professional. He listened to the details of my matter and offered his expertise on how we could resolve my issue. My case was atypical and we faced complications during the process that were beyond our control. Yet, Mr. Mullen kept finding solutions to every challenge we faced and we finally prevailed as a result of his expertise and steadfast persistence. Getting the outcome I specifically hoped for by itself was a great victory. This victory was heightened when I found a competent and skillful representative with honest fees in Mr. Brian Mullen. I am smiling from ear-to-ear. Thank you also to Cheryl and Nuha, who were part of the winning team.

I rarely write reviews because they are normally not warranted. In this case, I feel I need to share my experience of over 6 years working with Wilkinson and Finkbeiner law firm, specifically with attorney Brian Mullen and his para legals and secretaries on many family law matters. He has diligently guided me through several family law issues ranging from questions on the my original divorce settlement, child custody issues to child support issues etc. Brian's calm demeanor and excellent knowledge of the law has saved me time and money, however best of all positive results. His abilities have enabled me to stay in my daughter's life and fulfill my responsibilities of being a dad which I cherish and enjoy. He understands the emotional issues that come along with family law matters and fought hard for me using his legal knowledge and his staff. I always felt comfortable that they were on top of every issue. He always took time to listen to my goals and planned accordingly with great legal advice at a reasonable price to get to my goals. I am more that pleased , I am grateful for all this firm and especially Brian has done for myself and family. I highly recommend this firm and especially Brian Mullen.

I must say I’m definitely glad to have found Andrew and Brian from this firm to help me. They are awesome guys! They took the time to truly understand the inner kinks in my case and analyzed my case from every angle, not just telling me what I wanted to hear. They took the time to explain to me my options instead of pressuring me into taking a position that I would end up regretting. I must say this office is a well-oiled machine! They do things quickly and efficiently without sacrificing detail. The staff was also pretty awesome! Especially Cheryl! She was very helpful and was able to hone me in on the details that were very important in my case. They never went a few days without updating me as to new occurrences and kept me in the loop at all times which I loved! I can’t say I have any complaints about my experience with them. I would highly recommend this firm to anyone who needs family law help. There should be more attorneys like them out there. 🙂

I am the court appointed guardian for a relative going through a divorce in California. I heard many times that it is not easy to fight a case from out of state. The judge overseeing the guardianship called this divorce case very complicated. If it weren't for Brian Mullen this case might not have been brought to a successful and long lasting conclusion. I finally arrived at Wilkinson & Finkbeiner after I had become very frustrated with the first lawyer handling the case. I had my first consultation with Brian several month before actually retaining him. He was ready, immediately, when I had to respond to a 24 hour notice ex-parte request after the previous lawyer had decided that he could not continue his representation any longer. After a several months long search, Brian had been recomended by another lawyer in San Diego. She had known him from the time they worked in San Diego county. I had asked her about someone she could recommend in Orange County to be able to handle the specifics of the divorce case. Brian Mullen has met all my expectations, especially after we had to come up with new strategies to bring the case to a successful conclusion. A key ingredient was to maintain a working relationship and build trust with the opponent in the case. The opponent had faced more than a hundred thousand dollars in legal bills from his former lawyer, a law office that is being described as a billing machine. As a result of that effort, I had to have legal counsel to respond to several frivolous requests which eventually were turned down by the court. After the initial battle finally all the facts in the case had come in due to the very knowledgeable paralegal Cheryl's effort and Brian's understanding of the legal process and specifics of the case. She and Brian were very resourceful. They had been able to explain to me every step on the way, enabled me to make informed decisions and fully understand the court process. They successfully prepared me for two weeks of court sessions and testifying on the witness stand, enabled me to negotiate with the opponent to bring home the points that could be settled out of court and only continue to litigate the issues in question. At every step Brian had been conscious of the expense we needed to incur to provide efficient representation of my ward's position. Brian recommended competent expert witnesses with whom he cooperated well. We succeeded in a sense that the court's decision was fair and based on complete information. I can highly recommend Brian to anyone who appreciates his somewhat quiet and problem oriented attitude. He does not make any promises that he can't keep and follows through successfully. He can successfully stand up to the top earners in the divorce business when he can rely on the merits of the case. I have a similar expectations of Andrew, but he was only involved in the case on one court date when he had filled in.
