Excellent Attorney, very professional and knowledgeable
My colleague and I were both very pleased working with Daniel through the course of our probate sale. We work with attorneys regularly but few have delivered so well. He always responded in a timely manner, and helped make the process go smoothly without any hiccups. I would highly recommend him.
