It was always great to know that Chuck had my back. He was always very professional and detailed oriented which was very reassuring. All attorneys involved said that Chuck was the best and he is!


Mr. Koehler always gave us a deep sense of caring with strong moral values. He often gave awareness of right or wrong and advised on ethical fairness, with final decisions up to us. Mr. Koehler, we believe, goes above and beyond what expectations anyone would have. An exemplary job, well done!


Over 60 years of requiring professional counseling services, I have never been better represented for legal counseling services than those provided by Mr. Chuck Koehler. He is absolutely top of the line. He excelled in an area of state statutory documentation that is seldom utilized involving garnishment procedures related to money judgment by financial institutions. His research and resulting effort resulted in a very rewarding conclusion.
