Family courts can be a scary and anxiety provoking thing to navigate, but Nathan and his team are there to help. I cannot recommend this firm enough.

We hired Ryan Rothermel for what ended up being an almost 2 year custody battle. We had a great experience in him, and his candid, no-nonsense approach, advice, and communication. Ultimately we came out with what we had hoped for, against the odds. We would definitely use him again, and recommend him.

If you have a family law matter, there is nobody else I would recommend other than Mr. Petersen and his exceptional team at The Petersen Law Firm! I hired Nathan during the middle of divorce proceedings, when my situation was going from bad to extremely bleak, and he was able to turn everything around for me and get me a very favorable settlement. His attention to details, mindfulness of my finances, exceptional team of Alina and Rachelle, along with his adept ability to navigate through the quagmire of legal issues surrounding my case brought hope and peace my way.

He held opposing counsel accountable and helped keep my character intact when my ex tried to ruin my name. Whether it was a hearing, deposition, or trial, I was confident Mr. Petersen and his team would be by my side and help fight for my rights as a father. I don't know what I would have done without the services of these amazing, caring, and exceptional people! From the bottom of my heart thank you for everything you have done for me and my daughter!

There are no words that can adequately express what The Petersen Law Firm means to me and my family.
Nathan and his team helped me through the toughest year of my life and made it so my family and I can enjoy life again. They gave us hope when we thought there was none to be had. There is no hyperbole in this statement. The dedication and effort that the team put into my case was second to none and we are eternally grateful for all they did. You can't go wrong with them.
