  • David Matthew Gross

    David Badanes is a professional, civil colleague. In our Suffolk County Custody case, which dovetailed into a divorce action, David and I were able to work in a collegial manner to bring a responsible end to the matters. His demeanor and manner allow him to be a zealous advocate, representing his clients' interests appropriately, while maintaining the rules of ethics and civility with fellow attorneys.

  • Brad S. Margolis

    I endorse this lawyer. I have reviewed Davids numerous entries on Avvo and found them to be highly competent and informative. Potential clients of his will be well served by retaining him and if i eve3r needed a legal opinion to support my own I would have no hesitation calling him for his expertise or to refer a client in his area. The fact he offers flat fees in many cases is a extreme benefit to his potential clients. BRAD S. MARGOLIS,ESQ.
