    I endorse this lawyer. I have known Frank for a number of years. He is well versed in all criminal matters having spent several years working for the Public Defenders Office. He is well respected within the legal community. He takes the time to have his clients check in with him regularly while their case is pending to make sure they stay on track for the best possible outcome. I recently referred a family member to him for representation in a criminal matter. I'm sure they will be in good hands and will benefit from his problem solving approach.
