  • Wendy Lynn Slavkin

    Mr. Longo's extensive experience and knowledge in the Probate and Estate Planning arena is evident in the incredible job he does for his clients. I have referred my own family members and clients to him for Estate Planning and, every time, they give him rave reviews. Not only is he a brilliant lawyer, but his overall demeanor and personality make him a stand out in our profession.
