Catherine is incredibly knowledgeable, professional, and kind.
I reached out to her with a trademark issue that turned out to be more complex than I expected, and Catherine was generous with her time, extremely thorough in her explanations, and never made me feel rushed. Highly recommend her to anyone looking for a trustworthy, responsive, and thoughtful trademark attorney.
