About me

Leonard M. Koltonow has devoted his entire career to helping injured accident victims in Michigan. He is a firm partner and has been an auto accident lawyer with Michigan Auto Law for more than 30 years. During that time, Leonard was named one of the top trial attorneys in the state, when the Michigan Association for Justice chose his closing arguments as one of the best.

Due to his impeccable practice, Leonard has achieved an outstanding reputation in the legal community. In fact, he is so well-respected by auto insurance companies and defense lawyers, that they often choose to proceed directly to binding arbitration rather than facing him in a courtroom before a jury. As a result, Leonard consistently secures large settlements for his clients prior to trial.

  • Steven M. Gursten

    I have been fortunate enough to have been mentored by Lenny, who has widely been considered one of the 10 best trial lawyers in Michigan for the last 30 years. I’ve worked with Lenny and tried cases with him. He is a true fighter for his clients rights. Yes, he has secured millions of dollars in verdicts and settlements and yes, he is well known and respected in and out of the courtroom, but see and read what his own clients say about him…they truly adore him because he cares, he returns every phone call, and he gets very involved in every aspect of their case to make sure things go right. He is what trial lawyers should be.
