  • Walter A Lesnevich

    've known Jon as a fellow lawyer and friend for over 30 years. We met in the same town, and played on the same softball team together. Simply put, he is the best at what he does. If you need an estate lawyer, he is at the top of his game. Jon is very experienced in estate law, and provides a steady, knowledgeable hand when dealing with estate matters. He's caring, trustworthy, and immensely knowledgeable. Plus, he's a devoted family man and an all-around great guy. I highly recommend you use Jon Mate as your attorney.
