"Kate Beurmann-O'Neill did a fantastic job representing me in what proved to be a messy, trying, and complicated divorce. The thing I appreciated most, aside from her sound counsel and legal expertise, was her genuine concern for my children and her commitment to doing what was right instead of what was convenient or expedient—a quality which truly makes her stand out against her peers. Thanks for everything Kate! And a big shout out to her paralegal, Tina, for all her behind-the-scenes work! Thanks for getting me through this, ladies." - Daniel D.
