Theresa Nguyen is an energetic and resourceful, English- and Vietnamese-speaking lawyer based in Renton, Washington. She takes pride in serving residents and business owners in King County, which she has been a part of for over 20 years, and surrounding local communities. For her, it is an honor giving back and adding value to the citizens of Seattle-Tacoma, whom continue to nurture her in becoming an elite attorney. Currently, Theresa is living her long-dreamt childhood dreams of becoming an attorney, entrepreneur and soon, philanthropist. 

Theresa passionately advocates for fairness & justice and fights for her client’s rights as a business owner, homeowner, investor, spouse. Growing up, Theresa witnessed a countless number of injustices among family and friends, and could only watch helplessly as the events unfolded. Today, as an attorney equipped with the right education and training, Theresa defends against her client’s infringement of rights, helps clients prepare and shield themselves from liability, and strives to correct wrongdoings that unveil within any business transaction, marriage, or contract dispute. 

Theresa's law office focuses on helping citizens protect their assets, build better businesses and secure their legacy. Clients leverage Theresa’s expertise and passion for the law and are empowered to a higher standard of living. Her very nature is to add value to the people and community she serves. 

The services she provides come from her experiences assisting her entrepreneurial family and friends in both business and legal aspects. Since a young adult, she has aided them in a wide array of tasks such as business planning and operations (took out the rest of sentence). 

Her abilities grew exponentially after acquiring her Juris Doctorate, Masters in Taxation Law and engaging in pro bono work at the Federal Tax Clinic. During this time, she also contributed as a legal intern for prestigious law firms, an Associate Managing Editor for an internationally published law journal, and a Board Treasurer for the Association of Business Law Students (ALBS). 

Theresa continues to gain knowledge and experience in Business and Law. Along the way, she builds strong, mutually-beneficial relationships with her clients and peers. Simply, the world is a better place when we all help each other out.

She encourages anyone who is considering hiring a lawyer to contact her for a consultation or invite her to lunch (given scheduling availability). 

Whenever there’s a need for legal advice or action, it’s always best to explore all your options. The sooner the better because later usually costs more.
Theresa often contributes her parents as her main source of inspiration and role models. It’s hard not to admire a father and mother of nine, working hard to make a foreign country their home. Although they were unable to speak much English, they were able to provide their children with the opportunity to succeed in life and that’s what they did. 

Through entrepreneurship, Theresa’s father was able to support his large family and also keep it together. His family was an integral part in all his business ventures - everyone contributed to the success. As some families grow apart in time, his grew closer. As some family ties get weaker, his got stronger. 

Family values, strong work ethic and giving back to the community. That’s what Theresa was taught growing up and now lives to represent and defend.

I sure wished I would have met Theresa before I hired the lawyers I had. This was a long drawn out case. My previous attorney withdrew from my case two months before the trial. My lawyer advised me to find a contingent lawyer, nobody wanted anything to do with a long complicated case, until I met Theresa. She is not a contingent lawyer but I was very pleased with her help. I had nobody to go to and I was broken. I got down and personal with her, she new in her heart what I was going through and she took me on as a client even though she was busy with all of her clients, she made time for me. I couldn't have done it without her. Theresa is a kind, sweet, down to earth kind of person. I will never forget her and I will always refer her to all my friends

Complex Immigration Case that Resulted in LPR Status
Theresa helped my wife and I with an incredibly complex and stressful immigration case that resulted in my wife's I-485 (Adjustment of Status) case approved! She's had an immeasurable impact in our lives and we'll always be grateful. We hired Theresa in late 2015 on a set of USCIS applications that required us to work together until February of 2017. She even attended our interview with USCIS in January. Along the way Theresa was always professional and helped us maneuver the complex US immigration system. Thank you Theresa!

Real Estate transfer Made Simple
I hired Theresa to help my family and I do a real estate title transfer. Theresa did a great job in making sure that the process was quick and easy. It was all taken care of all in one visit. Even nicer, Theresa followed up with me a few weeks later to make sure I've received my documents ok. Now that is good customer service!!

She's even great with Probates
Even though Theresa specializes in Business and Taxation laws, she even great with Probates! The reason why I didn't choose a Attorney who specialized in probate but her instead is trust. I fully trust in her to represent me in my best interest. She communicates regularly with updates and is easy to get in touch with when needed. My probate wrapped up very quickly than expected! She definately will be my laywer for all law related questions. I highly recommend her!
