John McMillan earned a Bachelor of Arts in History from Southern Methodist University before graduating from Baylor Law School, where he pursued a concentration in criminal law. During his time at Baylor, John was an officer of the Criminal Law Society and tailored his coursework and internships to build trial expertise. Among other things, John completed Baylor’s highly competitive Criminal Law and Voir Dire boot camps, which gave him hands-on courtroom experience from the very beginning of his legal career. John also interned for the U.S. Attorney’s Office for the Southern District of Texas, the Limestone County District Attorney’s Office, and an elite private criminal defense firm in Fort Worth, Texas, where he learned from experienced prosecutors and defense attorneys.

After earning his J.D. at Baylor, John worked as an associate attorney at the Kearney Law Firm, representing people charged with a wide variety of felonies and misdemeanors including DWI, murder, sexual assault, possession of child pornography, Medicare fraud, drug trafficking, bribery, and theft, among others. John next worked as an Assistant District Attorney at the Tarrant County District Attorney’s Office, where he specialized in DWIs and took more than a dozen cases to trial during his time with the office. This experience gives John a deep familiarity with the courtroom and positions him as an experienced and capable advocate from the moment a case reaches his desk.

John then moved to Wisconsin and began work at the Grieve Law Firm. He brought extensive courtroom experience, familiarity with prosecution and defense work, respect for his clients’ rights, and a deep ethical grounding to his legal practice.

Client Reviews on

In a world where legal battles can feel like navigating a stormy sea, finding a guiding light amidst the tempest is a rarity. Yet, in Attorney Adam Kachelski of Grieve Law, my family and I discovered not just legal representation, but a steadfast ally in our pursuit of justice. With consummate skill and unwavering dedication, Adam Kachelski navigated the complexities of our family law case, leading us to the precise outcome we sought.

I chose Grieve Law to help represent me during my 1st DUI. My attorney Adam Kachelski had a large case with all my different charges. He was so amazing and got a great deal for me! I have never been happier, and I will suggest anyone that falls in the same boat as me to hire Adam or any lawyer that works at Grieve Law.

I worked with attorney Julia Westley for my owi case. She was always very responsive to any inquiries I had even after my sentencing. I could always tell that she genuinely cared about where the case was going and felt that she had my best interests at heart and it wasn’t just about getting the case over with. Would highly recommend.

Very competent and knowledgeable professionals. Would trust first before any other option.

Before I went to Grieve Law, my lawyer said it was unlikely that my criminal charges would be dropped or changed. Grieve Law was able to negotiate everything down to a ticket! I will forever be thankful for Grieve Law’s negotiation skills and help with my case.

Adam kachelski was one of the best lawyers I have ever had. I had a difficult case and Adam was there for me every step of the way. I have hired lawyers in the past for the same case and have only seen results through this lawfirm. Completely changed my opinion on lawyers and is worth every penny I spent. One of the things I personally like best about Adam and this lawfirm is that they are genuinely involved in your case and always responded to me in a timely manner.

Amy is what all lawyers should strive to be. All firms should try to emulate Grieve Law. I had a consultation scheduled quickly, affordable rate were offered, quick responses once hired, and everything was handled in the utmost way of professionalism. Someone answered every time I called, I was always given then answers with all the information needed to make a decision, and their guidance helped solve my issues immediately.

Best defense attorneys! Tom and his team are professional and easy to work with. They took immediate action on my traffic ticket. I would HIGHLY recommend! These guys go above and beyond. Thanks Tom!

I had Julia Westley as my attorney handling my offense. Throughout our time together, Julia was very responsive to my questions, kept me informed and did some great persuasion on my behalf with the DA. She was able to get the charges lowered and now I am able to move on and learn from the mistake. Great work and amazing job by this law firm!
