Washington Law Firm - Attorneys specializing in Tax, Probate, Business, Real Estate, Estate Planning & Immigration
We pride ourselves in producing positive results for our clients by focusing on 3 key factors: Knowledge, Experience and Competence. At the Law Office of Theresa Nguyen, PLLC, we have everything you are looking for in an attorney. If you need representation or advice to resolve a deceased loved one’s estate or assets, transfer real estate, form a business, plan your asset distribution, or dispute a tax liability, we are here for you. 

Often times, in the middle of a legal dispute, questions or concerns will arise that require knowledge of various areas of law and the balance between local, state and federal laws. For King and Pierce County residents, we are an excellent choice for an attorney as we have a strong grasp on all three bodies of law.

Whether it is a federal-, state-, or local-regulated agency, the Law Office of Theresa Nguyen, PLLC can help you resolve any disputes or issues you have with them.

Sometimes, a legal problem might not just entail one area of law; it may involve multiple practice areas. Our law firm is ready to tackle such complex cases. Not only do we specialize in Washington and Federal Law, we can analyze your case with scrutiny, by being knowledgeable on a diverse scale of law topics. For example, you may be going through a tax audit with the IRS, and want to know your Estate Planning options. Or maybe you have real estate you want to sell that requires a release of a tax lien, probate, or contractual dispute. Don’t depend on a law firm that only specializes in one area to counsel you. It is imperative that you take advantage of all the legal rights and strategies provided to you by law.

At the Law Office of Theresa Nguyen, PLLC, we care about our clients and we work with integrity. Many times in our profession, lawyers are retained and clients are kept in the dark about what strategies they should take or what is going on in their case. Our Law Firm provides one-on-one treatment and our clients are always informed of where the case is heading, what options the client may have, and we will only execute after consulting you. You tell us your goals or problems and we will provide you with solutions. We only take on cases where we know we can provide competent representation. Even if we do not take your case, we will guide you in the right direction and refer you to our comprehensive network of attorneys in the area.

Our law firm, attorneys & staff are client-focused & results driven.
