Contact Us


Each client who walks through our door is experiencing or has experienced pain: physical, mental, financial, or emotional. We approach each case with a desire to help the healing process begin. We care about each client and want what is best for them. Unlike many law firms where clients only speak with legal assistants or paralegals, our clients meet one-on-one with their attorney. Our clients need us to be their voice through the legal process. We feel the weight of this responsibility and know the great trust placed upon our shoulders. Throughout our representation, we do all we can to take as much burden away from our clients as is possible.

Let’s Talk About Your Case


Despite being a litigation firm (an arena known for being adversarial and contentious), the attorneys at Riggs Ellsworth & Porter enjoy an AV rating by Martindale-Hubbell. This means their peers – including their adversaries – were interviewed by an independent firm and ranked our attorneys in the highest echelons in competency and ethics. The legal profession is known for being unethical and dishonest: it is our goal to bring honesty and integrity back to the justice system.

Frequently Asked Questions

Our Clients

“We found the team at Riggs, Ellsworth and Porter to be excellent. We needed to update our trust after moving from CA to AZ. Gary helped to clarify the changes and explained so slight nuance differences from CA to AZ that we should look at. Overall excellent experience and will recommend or use them again.”

Brian Y.

“I have known Mr. Ellsworth and his staff for many years. I never needed an attorney before until recently, with regards to a case with my foster child. He was very prompt and thorough. He had the "heart of a teacher" and explained the legal process and terminology in a way that was easily understandable. Very satisfied with his service and the professionalism!!”

David B.

“I felt relieved after talking with Matt Riggs, Joanna and Chance about my auto accident. They were very caring and capable and are going to help me navigate through this very difficult time after my accident which is even more important since I did not receive the guidance and assistance I expected to receive from others. Thanks to the entire team.”
