About Stephanie

Learn Stephanie’s areas of practice.

 I am a partner at Deno Millikan Law Firm, PLLC. I’m a trial lawyer, and I use my legal skills to help my clients in a broad variety of cases. I’ve been honored by the Willamette University College of Law in Salem, Oregon by serving as Note and Comment Editor of the Willamette Law Review.

I’ve been identified as a Washington State “Super Lawyer” by Washington Law and Politics Magazine in 2003. I’ve been active in the Snohomish County Bar Association, and in 2010 served as Trustee, being elected as Vice President in 2011, and the Snohomish County Bar President for the year 2012. I continually work with other attorneys and in seminars to develop better and better trial skills. Part of that work has been through training offered to trial attorneys in the Spence Trial Lawyers College regional programs. The fact is, that most legal trials are battles involving the mind, persuasion and advocacy, but often not recognized is the fact that trials become matters of the heart as well. Developing these skills and my caring for my clients’ issues has been the key to success for me, and for my clients.

Snohomish County is the place where I was born and the place where I grew up. This community shaped my vision of who I wanted to be in the world and how I wanted to live. The values that I grew up with are the value of hard work and the satisfaction that comes from hard work, the value of integrity in dealing with my clients, my associates, the Courts and opposing attorneys. Finally, I was taught and enjoy the happiness that comes from helping someone else. These values led me to become a lawyer, and these values are a cornerstone of who I am as a lawyer and in helping my clients resolve their important and difficult problems.

My work as a trial lawyer encompasses a variety of legal areas, most of which may require a skilled negotiator or advocate at trial. Complex divorces, personal injury cases, and difficult commercial and business problems occupy the bulk of my legal time.
However, we live in a community that has a lot of non-trial problems, involving leases, contracts, land disputes, and all sorts of other problems. Helping my clients solve their weighty problems is one of my favorite parts of the legal profession.  I also serve as an arbitrator with Snohomish County’s Mandatory Arbitration Program.

I always knew that I would return to Everett after finishing law school, to raise my family here. I love being able to share the same things with my daughter that I enjoyed as a kid. Whether it is skiing at Stevens Pass with my family and friends, walking though the Evergreen State Fair on a rainy August afternoon or hauling in a crab pot off Whidbey Island, this is the place that grounds me.

Thank you Stepahnie
I met Stephanie the day after severe car accident in February 2016. At the time I had no idea how badly I was injured . The first thing Steaphine advised me to do was be treated. This became a 31/2 years journey. Of surgerys , doctors and therapists. The worst was a brain injury. Through all of that Stepahnie was always on my side. Fighting for me encouraging me . She always told me the truth. She became a advocate for me . She never quit even when I wanted to . She always respected me and all decisions were mine. But she always gave me wise and valued council. Her faith in me and my case gave me the courage to keep fighting . I have worked with several attorneys in my life . I have never met one who cared so much about me as a person and really understood what I felt and the loss I was experiencing. One of the best decisions in my life was hiring her as my attorney . Stepahnie is just a great human . Her integrity, honestly and devotion are in unmatched. She is a very skilled attorney and negotiator . Thank you Stepahnie for helping me get my life back. Pete!!

Outstanding representation
Stephanie Peterson embodies, professionalism, empathy and attention to detail. She is knowledgeable and committed to getting results that benefit her client. Her conduct and ethics are beyond reproach. Stephanie argues the law and maintains the integrity of the judicial system by not engaging in, or being drawn into, insults or mud slinging behaviors. Her sole focus is achieving the best results for you. At the end of my ordeal, I was proud to be represented by such a class act.

Knowledgeable, Professional, Compassionate
I have retained Stephanie's professional services multiple times over the last 7 or 8 years. She is my "go to" attorney for all Family Law related issues. She successfully helped my wife and I acquire the necessary custody needed to raise our niece. Our niece is now a happy well adjusted young adult. Further, Stephanie has represented separately a friend and a family member each through nasty custody/ divorce proceedings. I highly recommend Stephanie to all my friends, family, and employees.

Heart and tennacity
I felt like I had a true partner and an advocate with my personal injury case. She listened, did thorough research into the case and found legal avenues to help me. She understood and clearly communicated the legal strategy -- both pro and con. I would ask her to be my attorney again in a heartbeat.

High Praise for Stephanie Peterson
Ms. Peterson but an issue to bed for us that had been dragging on for 2 years with our other attorney. She is agressive but respectful and professional. I was definately glad she was on our side. She is in demand and therefore very busy and tightly booked. We take this as confirrmation that we have a great attorney but it can be difficult if you have an issue you need to talk with her right now. Her paralegal is great.

Stephanie N. Petersen is worth her weight in gold
Stephanie and her staff were fastidious in tracking my investments during a divorce. Their attention to detail, understanding of investments, and willingness to track money from one place to the next were invaluable to me in the final outcome. I had originally hired another woman attorney. She paid little attention to my case and it stalled in its early stages for months. I finally told her I needed to find someone else to manage my divorce. She recommended several attornies . I interviewed each of them and chose Stephanie. Because of Stephanie'sexpertise in handling my divorce, I have continued to use her for other purposes. She is intelligent, an excellent communicator, highly respected by her peers, and quick to grasp a situation. I am grateful to have worked with Stephanie.
