Went to this Attorney with a crazy case and boom he knew exactly how to take care of things.
Thank you so much for all that you’ve done! I couldn’t have gotten through this divorce without your words of wisdom, advocacy skills, professional legal advice, expertise about family law, relentless confidence, and sincere understanding. You didn’t treat me like I was just another “court case”. What you did, among other things, was listen to every word I had to say! That was important to me because—not once, did I ever feel that you weren’t genuine. Once again, thank you Chris!

Highly Recommend
Great law firm! I had never needed representation before my divorce and had no idea what the process was or how to go about it. With the help of my attorney's, my case was settled precisely as Sunnen Law had laid out according to my wishes and agreements with my estranged wife. I would highly recommend this firm if you are looking for a divorce attorney.

Crème de la crème
Knowledge is power and that is exactly what you have on your side with Sunnen Law. Chris Sunnen helped me navigate through a few delicate situations. He put my mind at ease and was well prepared for all court hearings. His staff is professional, returns all correspondence and calls timely. I highly recommend Sunnen law and happy with my outcome. Most important and I have not found in an attorney is compassion, Chris Sunnen is an anomaly. Compassionate, dedicated and a true professional. Hats off to you to you and your staff.

Highly Recommend for help
Excellent Attorney ! Thank you to Chris and his entire staff for helping me with my restraining order case and child custody case. Chris and his team were patient and kind. I honestly would not be here today without them. Not only did they defend me in this case but I now have more time with my children. I highly recommend Sunnen Law.

I am forever grateful that I retained Sunnen Law Firm to work on my divorce. I am happy with Attorney Christopher Sunnen and his entire staff who worked on my case. I liked how realistic and honest Chris was with me on my entire case, which helped to easy my concerns. I would definitely recommend Sunnen Law to everyone as he not only has the experience and knowledge but he’s also very polite and caring during a stressful time.

Divorce & Child Custody
Chris handled both my divorce, child custody modification, and handled the adoption with name change to my spouses last name. Mr. Sunnen and his staff did a great job of keeping me well informed on everything going on. They always calmed me when things got messy assuring me to stay focused. My second ex's attorney described Chris being “tough as nails” which is a great recommendation coming from opposing counsel. Mr. Sunnen knew all the Judges and lawyers we were dealing with and he has a great reputation. I wouldn’t work with any other Attorney. Thank you Sunnen Law for all your hard work and dedication.

Mr. Sunnen and his staff were excellent throughout my divorce and custody case. So much in fact, that I hired Mr. Sunnen again for our change of custody case a year later and my Bankruptcy. He did a great job of answering all my questions and gave honest, sound council. He is very personable, but an absolute professional as well. While I would not wish our circumstances on anyone, my kids and I were fortunate to have had Mr Sunnen represent us and I highly recommend him!

I needed a lawyer ASAP !!
I was going through a really hard time, and being a single parent it's sometimes hard. Attorney Chris Sunnen helped me with my divorce. I was very happy with the results and the price he gave me, divorces sometimes can cost a lot of money $$$ . Attorney Chris Sunnen made me feel at ease. I also needed someone to do a bankruptcy for me and yes of course I called the attorney Chris Sunnen again. I am very happy on the outcome of my divorce and my bankruptcy . Really nice attorney , he also has a great staff that works for him they are all very nice. Thank you so much attorney Chris Sunnen !!

Fights for families
I consulted with Chris and liked his plan and advice. Once I hired him, Chris and his team took my case and not only did Chris fight for me and my children but his team really put an effort into showing the court what was best for my children. In the end, I was happy with the results and recommend Chris and his team to anyone in a family court case.

Honest, straightforward, efficient & effective
Mr. Sunnen handled an urgent custody matter for us. He gets straight to the point and he is very knowledgeable. He doesn't waste time and he doesn't waste money. As a member of the legal field, I was very pleased and impressed with his clear communication, professionalism and effectiveness. He resolved our matter as predicted and we are forever grateful. I would highly recommend him.

Amazing results and quick at responding
I would recommend anyone that has a child support/child custody case to contact Chris as he is not only informative but easy to talk to as well. After incurring several fees with another attorney which seemed like my case was going nowhere a friend referred me to Mr. Sunnen who was able to resolve everything in the most cost efficient manner. I got the results I wanted without all the additional fees the other attorney was charging me. I can't thank you enough Mr. Sunnen for all you did for me and my children.

Professional, Straightforward and Honest - Highly Recommended!
Christopher created a Release of Liability waiver for me to begin offering my services to customers. He gave me the confidence to move forward with the next step in my business. He was very professional, straightforward and honest, and I wouldn't hesitate to recommend him in the future.

Extremely Knowledgeable and Experienced
I was referred to Mr. Sunnen by a previous client and friend of mine. I needed assistance with a trademark application in which The Law Offices of Christopher Sunnen was able to take care of immediately after I dealt with 3 other firms who bounced me around. This is a full service IP firm that has helped us with just about anything you can imagine when it comes to IP law and other matters affecting your brand. We've worked with them for over 3 years now and they have helped us build a portfolio of trademarks and copyrights that is one of our businesses core assets. They are great to work with, offer a ton of added value and have been very helpful throughout our time working with them. I highly recommend the Law Offices of Christopher Sunnen for any of your legal needs!

Best Tax Attorney in San Diego!
I was experiencing some tax issues from several years past and contacted several law firms while attempting to find representation with the IRS regarding my tax issues. Being an Ex-Patriot and having lived overseas for several years while attempting to find a firm to assist me over the phone wasn't a very easy task until I contacted The Law Offices of Christopher Sunnen. This firm was like clockwork. I appreciated that I never had to spend much time 'on hold' when calling their offices and that I always had easy access and direct access to the attorney who was assigned to my case. Unlike a previous firm I used for a previous issue, I never had to wait very long for responses from my attorney at Sunnen Law Firm, and he was extremely good at keeping me up to date whenever there were any changes in my status/case. I am very critical of customer service when dealing with companies while residing overseas, and I have nothing but good to say about The Law Offices of Christopher Sunnen. It is with great enthusiasm that I recommend their services to you.

Best Attorney in San Diego- honest, straight forward and gets the job done right!
I have worked with several attorneys who gave me the run around on how to resolve my issue and quoted me excessive fees for unnecessary work. A friend referred me to The Law Offices of Chrostopher Sunnen who was able to resolve my issue and knew exactly what to do with minimal work and cost compared to what other firms were telling me. My issue was resolved quickly and in the most efficient manner. I will never go to another attorney other then Mr . Sunnen again. Myself, wife, and family couldn't thank you enough for all you have done. Thank you!!!

Tricked me
A year ago I found Christopher John on Avvo, and because of good reviews I decided to go to their office for consultation. In the office I got a free consultation from MR Hannosh who works in Sunnien Law as an attorney. He said that they work together with Christopher. He was very nice and helpful and I decided to hire them to work on my divorce case. I worked with Sunnien Law and Mr Hannosh on my divorce case. I paid them for my divorce 4000$ in advance. As soon as I realized that Sunnien law spent all this money, I wrote them a letter that I don't want to work with their agency anymore, because I don't have a job and money and I am actually an international student. In 2 month they sent me an invoice and said that I have to pay them almost 4000$ on top of what I already paid. I feel like these people tricked me because my English is not very good. They did a very bad job with my divorce case. I finally went to the court alone. They did everything to charge me as much as possible and do a very little job. They work very badly, don't pay attention to details and they don't care about the result. NEVER hire them.

Response from Christopher Sunnen July 26, 2022
We are sorry to hear about your experience as we are usually known for our exceptional customer service and we regret that we didn't live up to those expectations here. I personally have never consulted with you or met with you. I also have never received any emails or phone calls from you in regards to any possible complaints you had with any of our attorneys here at the firm. Unfortunately, the information you are using to review our business in the public light is false. Upon further review, it appears you corresponded with our receptionist in response to your unpaid balance. Our receptionist responded to you via email on 07/25/2022 to arrange a payment plan. You may contact our office to discuss any specific charges you feel are inaccurate and we will be happy to review it.
