Stephanie N. Petersen

About me

 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.
