"I had the pleasure of working with Laura B. on some recent legal matters, and I genuinely can’t recommend her enough. From start to finish, Laura was professional, responsive, and incredibly efficient. What really stood out to me was how thorough and proactive she was — she didn’t just check the boxes, she went above and beyond to make sure everything was done properly and on time. Legal work can feel overwhelming, but Laura made the entire process smooth and stress-free. She explained everything clearly, answered all my questions promptly, and stayed one step ahead the entire way. I never had to chase her for updates — she was always on top of it, which gave me a ton of peace of mind. It’s rare to find someone who combines legal expertise with such a down-to-earth, approachable style. I felt like I was in really good hands the whole time. I’ll absolutely be working with Laura again for any legal needs that come up in the future, and I wouldn’t hesitate to recommend her to anyone looking for a sharp, dependable, and genuinely helpful attorney."

I have been a litigator in state and federal jurisdictions throughout the United States for the past 15 years, save for an eight-month stint as General Counsel and Chief Compliance Officer for a credit card processing company. I am an asset to any firm looking for support with any type of motion work or coverage for appearances, if necessary. I like to refer to myself as a self-proclaimed "walking code of civil procedure." I look forward to working with you and helping however I am able. Thank you for your consideration.
