    Hired Attorney 2020-2022
    Do not hire this law firm for domestic violence he played around for 2 years with my case he would never return our phone calls he also did not show up for court even though he said he wanted to be the one to tri our case he sent in a stand in he never asked for my side of the story in the end we took a plea deal because we was not confident that his law firm would fight for us he was banking on my daughter not showing up despite the fact I told him she would and did every single time he only takes domestic violence cases because it an easy $ 2,500 a person in my case $5,000 between me and my husband saying that these cases just go away wake up Bill and take domestic violence off of your website, when we went to court I took a plea deal the layers that showed up that day did not read the statement she made that day it was yet again a different story from what was in discovery so they could have poked holes in her story big Time but it looks like to me at the time Bill was more focused on that crack pot Donald Trump case now that I seen an article about it h seems so proud to defend an election denier and insurrection cop killer.
