Thank you again to the team at Oliverson Law.
From the moment I called and spoke with Derek, I felt connected and relieved. He was very responsive and listened to my situation. After my dui arrest, I was worried and concerned about what may happen. The team took a lot of that stress into their hands away from me. They kept in contact with me throughout the process and if I had questions they were quick to respond. After a few court dates, Derek gave me a call personally to tell me that the prosecution had dropped all charges. It was an early Christmas present a few days before Christmas. Thank you again to the team at Oliverson Law.

Unfortunately recently I was arrested for a DUI and more unfortunately this was not my first DUI. I did a quick Google search and found Oliverson Law. I filled out the online information card and got a quick phone call back. After one conversation I felt very comfortable that this law group knew what they were doing so I decided to go with Oliverson Law represent me. During this process this law group was available through text email and phone calls 24 hours a day! Anytime I had a question I could send a text and it was answered quickly. When my court date was approaching their team called me and let me know how to prepare for my in person court date. When my day in court came I felt prepared, every member of the team was on the same page. I am very happy With my experience and the outcome of my court case.
