Dui appeal
After being denied from SOS for my drivers license Ms Mas suggested to go to the court to appeal the decision. I could tell she was sincere in trying to help me get my life back on track. She was always in contact with me. Helped me more than I could of asked in getting my letters & other documents in order. She went over & above to communicate with the SOS after I did not receive any correspondence. I would not only recommend but also have her help with any other incident I may need.

The Best!
Betsy went above and beyond to help in getting my license back. Honestly there’s no way I’d have it if I didn’t have her help. Highly recommend her to anyone. There’s a lot of lawyers but not a lot of them fight for justice and she definitely does

Truly cares about her clients!
Contacted for a drivers license appeal hearing. She took the case on short notice (5 days including 2 weekend days). She put her whole heart and soul into my case it felt like. She called me in between other clients to discuss my case and asked many questions. She researched things to calm my anxiety over what was to come. She attended the hearing with me and helped me get more than I even expected from the hearing. I went in with hopes that the best case scenario would be for the hearing officer to allow me to continue to drive for another set amount of time with the BAID in my vehicle. I walked out of the hearing with my FULL license reinstated. She went above and beyond my expectations.
