Lazy and rude

It is difficult to reconcile the credentials and experience this attorney claims with the treatment I received. Throughout my case, I felt disrespected. Simple questions were met with raised voices and dismissive behavior. At one point, I was told to “man up” and informed, “You’re going to be f_cked ...in jail; that’s what they do to transgender people.” Beyond such inappropriate remarks, I was denied access to my case file and discovery. This information is essential for securing new counsel. Being told it would be handed to my next attorney at a later court date would have wasted critical time. This attorney repeatedly misstated facts about my case, and responses suggested unfamiliarity with the details. After taking $2,500 and leaving me mid-case, I was left in a difficult position financially and legally. In the end, he gave me false information about my rights as a client, his obligations as my attorney, and my right to review my discovery. I expected professional, competent representation and received hostility, aggression, and misinformation. Michael tells me it’s his responsibility to make sure his clients learn from their mistakes or else they’ll have fallen into a life of criminal uselessness.

Experienced DUI attorney

Michael has been practicing law and helping folks with DUI arrests since before most of his clients were born. That is not meant to be disparaging of his age, but the fact is that that experience--knowing the personalities involved and the "ins-and-outs" of the Martinez courts was invaluable. Micha...el and I worked together to prepare a case based on my actions that resulted in a better outcome than I had expected.

Michael is more than an excellent attorney

Facing the shame, guilt and remorse of being charged with DUI and hit and run I looked for an attorney. I was blessed to find Michael. Michael immediately told me I was not alone and laid out the process in an easily understandable way. There were no surprises except for a good one. Everything went s...moothly as planned. Michael is professional, knowledgeable and kind. I highly recommend him.

Helpful Life Change

I hired Mr Semansky for a troublesome Domestic Violence case, The injuries were serious and alcohol had been a problem in my life. Mr Semansky made me feel comfortable was non judgmental and worked with both me and my wife... me to get sober and do therapy and her to seek counseling and join Al=Ano...n, The case resolved successfully and the ordeal, particularly Mr Semansky's intervention ,saved my life and my marriage

Avvo Rating

Our Rating is calculated using information the lawyer has included on their profile in addition to the information we collect from state bar associations and other organizations that license legal professionals. Attorneys who claim their profiles and provide Avvo with more information tend to have a higher rating than those who do not.

What determines Avvo Rating?
  • Experience & background Years licensed, work experience, education
  • Legal community recognition Peer endorsements, associations, awards
  • Legal thought leadership Publications, speaking engagements
  • Discipline Disciplinary information may not be comprehensive, or updated. We recommend that you always check a lawyer's disciplinary status with their respective state bar association before hiring them.
