Verified ClientHired Attorney 2013-2020Mr. Bonsib Has Represented Me On Several Occasions Including Both Criminal And Traffic Matters. I Am So Grateful For His Services, Because The Outcome Of Those Proceedings Were In My Favor. Anytime I Called Mr. Bonsib Whether On His Personal Cell Phone Number Or His Office Number, I Was Always Able To Speak To Him Directly. When I Was Quoted The Price By Mr. Bonsib To Obtain Him As My Attorney, I Was Caught Off Guard Because His Prices Were The Same That I Was Quoted By Other Attorneys And Law Firms In The Area, But None Of Them Had The Level Of Experience And/Or The Reputation That He Had. Mr. Bonsib Should Be The Only Attorney You Call If You Ever Need A Lawyer, Because He Deserves It And Earned It! Thanks Again, Mr. Bonsib For All Your Hard Work!

Hired Attorney 2021-2024Bob knows what he's doing I was charged with a very serious felony and from the bond hearing to the acquittal at trial it felt more like he was more in charge than the judge I told you right after the not guilty verdict that I owe you my life Bob and me and my family are forever grateful
