    The most courteous, respectful, and knowledgeable firm

    Without a doubt, the most courteous, respectful, and knowledgeable firm and group of people assisted me during tough times. Christopher was honest and direct throughout the experience, answering every child-custody and legal question I had. Everyone at Sunnen Law truly seemed to care about me and the outcome of my case, treating me like a friend rather than a client. I hope to never need their assistance again, but if I ever require legal help, there would be no hesitation in having Sunnen Law represent me. Thank you!

    My attorney got real progress in my case

    Every was very nice and supportive. My attorney explained everything to me and the office took care of everything. I tried on my own for years with no progress. After a couple of months my attorney got real progress in my case.

    Mr. Sunnen was always available to talk

    I cannot speak highly enough of Christopher Sunnen. He is one of the most professional, detailed, and knowledgeable lawyers I have retained and dealt with. Mr. Sunnen  gave excellent and professional advice on how best to represent and protect my asset value. He was always honest and direct and provided excellent work in preparing legal documentation and positioning my case as strongly as possible. Mr. Sunnen was always available to talk and offer good advice with all the difficult aspects of divorce: child custody, financial issues, child suport, spousal support, what to expect in the divorce process. .etc. I highly recommend the legal practice of Christopher Sunnen.

    I’ve done right in my life, it’s hire Mr.Sunnen !

    I was highly skeptical about hiring a lawyer for my what I thought a simple divorce matter that turned out to be highly complex. Mr. Sunnen was worth everything. His prices are fair, he took on my case with less than 24 hours notice and his response time was amazing. I’d say I was a pretty needy client and it didn’t matter what time I texted him I received an immediate response addressing my concerns and easing my worries. He has an outstanding way of making you feel comfortable with whatever the outcome will be. I never once felt like I was in a losing situation. If there’s anything I’ve done right in my life, it’s hire Mr.Sunnen !

    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.

    I couldn’t have gotten through this divorce without your words of wisdom

    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!

    Chris is always professional

    After I had a really nasty experience with a local attorney and tried to self represent (a very rapidly moving custody case) I found Chris. I wish I could disclose the details of my case and how far we’ve come.
    Rosemary is absolutely amazing. She is on top of her work and has been someone who’s listened when I’ve been in the office for hearings etc (briefly bc she’s busy). Mareva is on top of her game. We have tackled a few things pertaining to my case together and moved right along. Chris is always professional and has been there to calm me down, explain a situation, and work through next steps. Together we have tackled court hearings, depositions, handled very aggressive/unprofessional opposing party representation, and (finally) worked through a custody agreement in my favor. Chris has provided accurate and solid advice – even when I didn’t want to hear it. He understood my priority was my child, his safety, and well being on day one. I needed that support.
    Even though I would hate anyone go through a custody case, if you’re searching for an expert in Fam Law, don’t look any further.
    Chris, you have helped reach  peace of mind today. Thank you to you and your staff!

    Chris and his team answered all of my questions

    I phoned Chris’s office with questions about custody and how to proceed with me being in the Military. Chris and his team answered all of my questions over the phone and gave me really sound legal advice. Never did he try to reel me in as a client. He was very straightforward and honest wirh my case and provided me with options on how I could move foward and if i should even go foward at this time or wait it out. I appreciated his transparency and will hire him when I return from my leave.
