Excellent Service
Marlo was personable, easy to talk to, and available when needed. She gave frequent updates and even went beyond expectations in accelerating my sentencing guidelines. I highly recommend her services!

No DUI conviction!
Although the BAC test result came in at nearly twice the legal limit for Driving Under the Influence, Ms. Cordero skillfully obtained a reduced charge of wreckless driving instead of the DUI conviction I was faced with. Many thanks to Ms. Cordero and the Barry Simons Law Firm which represented me.
