    I went to law school with Isaac, and I have worked with him at the District Attorney's Office. I have known him to be very professional, attentive to detail, and diligent. He is adept at handling legal matters in a variety of fields. In addition, if I have a question on one of my cases, he is always more than willing to assist me. He is reasonable, a hard worker, and an excellent legal writer.
