John Larson represented me through a genuinely difficult family law matter, and what stood out most was how much he cared — not just about the legal strategy, but about me as a person going through it. He was patient, understanding, and never made me feel like just another case file. Highly recommend if you want an attorney who treats you like a human being first.

I retained John Larson after he eagerly offered to help with my custody and child support case, and I made the mistake of paying him up front in full. The core problem was pace and communication. Multiple requests for updates on my own case went entirely unanswered, including several where I was simply asking where things stood. I frequently had to call, text, and email repeatedly to get any status at all. No discovery was ever conducted on the opposing party’s finances, despite that being central to the case and despite my raising it. I ended up having to pursue that myself later. The worst moment came on the day of a child support hearing. I called his office roughly five minutes before it was scheduled to begin, and he told me himself that he could not appear and that I should get another attorney for my child support case. I had to go into court alone to request a continuance, with no notice and no preparation. When I terminated the representation, I requested a full refund of unearned fees and an itemized accounting. He declined to provide a full refund or itemized accounting. I have texts and emails documenting all of this. I lost thousands of dollars and, worse, a year of progress on a case where timing mattered. If you are considering John Larson for a family law case involving custody or child support, I’d highly recommend looking anywhere else.

John was an incredible advocate during a very stressful legal battle with my ex, who had hidden her bonus and only pursued action after learning about my recent earnings. John guided me through the entire process, defended my legal position, and ultimately helped secure a favorable ruling from the judge that put an end to the unreasonable demands. What impressed me most was John’s courtroom presence — he came fully prepared, read the judge and the situation perfectly, and used that insight to deliver a decisive win. I’m truly grateful for his expertise and dedication.
