Our firm is home to not just great lawyers, but a Super Lawyer (Thomson Reuters West designation) in Mike Nichols. It doesn’t stop there: Mike Nichols has been named one of the Top 100 in the State for DUI/Criminal Defense. Mike Nichols has also been named as the Chair of the National Task Force on Forensic Science for the National College for DUI Defense, leading a group of roughly 10 lawyers from across the nation, who are experts in forensic science in their own right. Wendy Nichols is also a leading lawyer in personal injury and domestic relations/family law. In September, Mike and Wendy Nichols celebrate 15 years in the building that they built from the ground up in East Lansing. 15 years later we remain committed to results.

The Nichols Law Firm Lawyers

Committed to Results - Find Out How

Founded in 2006 by the husband and wife legal team of Mike and Wendy Nichols, the Nichols Law Firm has grown to become one of Michigan's most effective and successful law offices. Our team of Nichols Law Firm lawyers are nationally recognized leaders in the areas of DUI, Marijuana, Family, Divorce, and Personal Injury Law. Attorney Mike Nichols has been repeatedly recognized as a SuperLawyer by Thomsen Reuters West for Criminal Law, in addition to authoring the Michigan OUI Handbook for WestLaw. No matter how big or how small the situation you find yourself in may be, you can trust that there is an honest and fearless advocate at the Nichols Law Firm waiting to help you get the results you need.

Having a run-in on the wrong side of the law can be the most nerve wracking experience one can face. The Nichols Lawyers know that the first question you likely think of after your arrest is “what’s next?” Being convicted of a crime can change your life forever. Whether you’re charged with OWI, Marijuana Possession, Misconduct in Office, or homicide, having a dedicated criminal defense team can mean all the difference in the outcome you experience. For people who are dependent on their Commercial Driver’s License (CDL) to live, they have no option but to fight the charges against them and avoid a license suspension.

With OWI or Drug Use charges, science matters. The Nichols Lawyers are nationally recognized leaders in challenging the police science and legal tactics being used against you. After years of fighting for scientific fairness, Mike Nichols secured a court decision which changed the face of forensic measurement in Michigan and states around the country by requiring that courts verify the validity of science being used against an accused person.

We are proud to have earned our reputation of being hardworking in every field we practice. Attorney Wendy Schiller-Nichols has tirelessly worked for more than defending the rights drivers who have been hurt in an accident by an at-fault driver. Attorney James Heos has spent 40 years fighting for the rights of his injured clients and securing million dollar verdicts.

Hiring the Nichols Law Firm does not just provide you with an attorney on your case; you’re hiring our full team. From the ground up, your case will be given the attention it deserves starting at the moment you walk into our office. We encourage you to browse our website to find more information about the law, police science, and how you can help your Nichols Lawyer build a strategy to secure the result that you need to move past your current legal issue. Through our commitment to results, we are excited to earn your trust.

The Firm Feeds a Family

Times have been tough around Michigan and the world with the impact of the COVID-19 pandemic on our economy. The Nichols Law Firm Team decided to do something to try and help. We partnered with the Greater Lansing Rescue Mission and our friends at Steakhouse Philly to at least provide 1 meal to people in need in the Lansing-area. On Tuesday, June 29, before Mike Nichols and Parker Myles left for a 2-hour trip for a trial, we came together to pick up meals from Steakhouse Philly, which is located just off Michigan State University’s campus, to deliver them to the Greater Lansing Rescue Mission on Lansing’s near-west side.



New Look at the Court in East Lansing

Judge Molly Hennessey-Greenwalt took the oath of office publicly on Sunday, August 22, 2021 at a ceremony in the court in East Lansing (shown here being administered by Judge Richard D. Ball). Judge Greenwalt became just the 7th Judge to preside at the court, designated as the 54B District Court when it was created by legislation in 1970.  Judge Greenwalt has a diverse background for a relatively short time in the legal profession. She worked at a private law firm while in law school. Judge Hennessey-Greenwalt then clerked for then-Michigan Supreme Court Justice Stephen J. Markman. We came to know the judge when she was an assistant Ingham County Prosecutor. She even tried a drunk driving case with Mike when she was pregnant and close to delivering her child. Judge Hennessey-Greenwalt then left the prosecutor’s office to go back to the Michigan Supreme Court – this time as a Supreme Court Commissioner. The job entails serving as one of about 15 lawyers, who advise the justices on everything from operation of the courts around Michigan to cases that should be reviewed for granting “leave” to appeal and everything in between. Judge Hennessey-Greenwalt was appointed by Governor Whitmer in late July to fill the seat vacated by the retirement of Judge Andrea Larkin. Congratulations to, and we look forward to working with 54B District Court Judge Molly Hennessey-Greenwalt in East Lansing.



Mike Nichols updates the 2020 OWI Book for Michigan Lawyers for Thomson Reuters West Publishing

Mike used the "downtime" with courts closed all over the state to focus on completing the 11th update of this vital book for Michigan lawyers as the publication enters its 2nd decade. "One of my favorite subjects was the City of Lansing v Reynolds" case - in which the Judge granted a new trial over a Brady violation by Geoff French at the Michigan State Police lab.



Did you know the Michigan Breath Alcohol Testing program is NOT accredited?

The Impaired Driving Commission released their report today about marijuana impairment in drivers. There is definitely some good stuff in there, namely:

  1. Recommendation against a per se limit – they said there is no way for that to be equally applied
  2. HGN is not effective for marijuana intoxication
  3. They recommend officers use unstandardized tests for marijuana investigations

WATCH: Are you “Claritin clear?” If so, you may want to decline allowing the officer to administer the Horizontal Gaze Nystagmus test.

One blow only; officers are required to ask for a second but you do not and should not need to do so

The National College for DUI Forensic Science Task Force brings you the following head-shaking tale

A lab analyst in Arizona was disciplined and then forced out of his job. Why? He told the truth on the witness stand even though his supervisors told him to change his testimony. He tried to sue but amazingly his case was tossed out of court. Why? Qualified immunity. “QI” is a concept that means government actors cannot be held liable for hurting people by their conduct in almost every instance but-for a few exceptions. We need changes. We need more transparency from government labs. We need to reform qualified immunity in Congress. A 2-fer of an update starts now:
