    I have had the pleasure of working with David for the past 6 months. David is extremely dedicated and hard-working. He is sensitive to his client's needs at a time when they are feeling vulnerable. He is an aggressive trial attorney who is tireless and driven, which serves him well both in the courtroom and outside of the courtroom.
