Why does Koehler Law practice only in D.C. Superior Court?

Jamison Koehler practices only in D.C. Superior Court so he can know the local practice and D.C. law in depth. Mr. Koehler does not divide his time among Maryland, Virginia, and D.C., does not work in federal court, and does not take personal injury, family law, or other unrelated matters.

This focus lets Jamison Koehler build strong working relationships with the judges, prosecutors, probation officers, and court staff who handle his clients' cases. Koehler Law offers experienced representation at reasonable, affordable rates.

What clients say

In their words.

Mr. Koehler is, as far as I am concerned, the best criminal defense lawyer in D.C. He walked me through things before I hired him, and literally everything he predicted came true. When I brought him on, it was clear that everyone in the courthouse respected him – judges, prosecutors, court clerks. At trial, he tied up the prosecutor with the rules of evidence, and he made the police officer look like a lying idiot. It was fun to watch. You almost felt bad for the officer. I was acquitted of all charges. I will be forever grateful to the man. Thank you, Mr. Koehler!
J.C., Simple Assault
I had never been in any sort of legal trouble until couple years ago when I was charged with a serious offense that would put me in prison for many years if convicted. After researching qualified criminal defense lawyers, I was fortunate to come into contact with Mr. Koehler. During the initial meeting, Mr. Koehler was very patient and sympathetic when I told him my side of the story. He explained the due process procedures and answered all the questions that I was unsure of. The case went on for another year and half because of the government investigation and proceeding. Mr. Koehler and his investigator contacted many witnesses and prepared them to testify on my behalf. Mr. Koehler also filed a number of motions to help fight the case. Thanks to Mr. Koehler's hard work, we got an offer on the eve of trial that we could not refuse. Not only were the two felony charges dropped, I will also come out of this whole experience without a conviction on my record. I highly recommend Jamison Koehler.
