Strong & Highly Competent Representation

Ms. Porter represented me in Dec 2025. She was very responsive, interested in the details and identifying the best defense and solutions rather than just going through the motions, she was very proactive and kept me informed on steps in the process and actions taken, etc. She was willing to go to tri...al as needed in order to provide comprehensive defense. The outcome of the incident is we went to a Bench Trial and I was found "Not "Guilty". I highly recommend Ms. Porter.

Great Experience - Exceeded My Expectations

From our initial consult, Karin laid out a game plan to help maximize my odds of success. She was easy to reach and very responsive. On the big day, I knew exactly what was happening every step of the way. My reckless driving charge was amended to a charge of failure to pay full time and atten...tion. I was hoping to have the reckless reduced to a regular speeding ticket, but I never expected that I wouldn’t even have the infraction reported to DMV. Every case is different, but I believe a great part of my success was due to the great representation and advice. Hopefully I won’t need her services again, but it’s nice knowing that I have someone I can count on to fight for me.

Grateful! Highly highly recommend!

Super thankful I was recommended Karin! Her guidance, professionalism, experience and expertise are exactly what I needed. I had 3 charges, DWI/obstruction related. Very scary situation for me. 2 were dismissed and the other was reduced to a reckless driving charge. Her pre-trial advice was incredibl...y helpful and beneficial, definitely take her recommendations. She did so many extra/above and beyond things to make sure I had the best outcome possible- forever grateful!

"One day I watched Karen try a prostitution trial to acquittal. She was cool and collected as she cross-examined the cop on the path of narrowing the possible avenues for a conviction. I trust Karen for discussing issues in my own cases. She is a capable lawyer."
