Worst dui (he’s the 1st of two) lawyer I’ve ever had. Long time ago but he wanted me to just plead guilty when I was a college kid and didn’t know what was going on- no breath tests, no sobriety tests. Worst lawyer ever . Review is a long time coming. College kid, who asked his father for advice, and this guy came up somehow. Should’ve been thrown out, there was absolutely nothing. DO NOT trust this guy, his clients interests are not at heart
