"Dan is a great attorney who is both deeply professional and responsible. Application drafted by him is both clear in logic and precise. Working with him is really an enjoyable process as he always keeps his customers in mind and tries to address their specific issues and concerns. For example, as a first time patent applicant, I’m new to both the patent application and the overall process. Dan guided me step by step patiently and professionally. He really listens to his customers and tries to help out. In short, Dan is the best attorney in my mind and I want to recommend him fully to anyone who’s looking for an attorney for their work."
