  • Bayard Marin

    I have known Mr. Erhart for several years. He worked in my office before he became a member of the bar. He impressed me not only with his intelligence and motivation, but his strong ethical and moral foundation. We have consulted over the years and I have watched him develop into one of the finest lawyers in estates and elder law in this area. I am proud to be his colleague.
