If you have a prior conviction, then talking to a lawyer about how you can clean your history can help your professional career.

I maintain a private criminal law practice. Currently, I represent people primarily in Lake and Mendocino Counties. I have completed approximately 50 jury trials (felony and misdemeanor trials) in Colusa County, Humboldt County, Lake County, Mendocino County, and Napa County. Argued numerous preliminary hearings, hearings, hearings, suppression hearings, motion to strike prior convictions, speedy trial motions, 995 motions, Pitchess motions, writs of mandamus and prohibitum, habeas corpus petitions, and misdemeanor appeals. In writ proceedings, I successfully argued a prior misdemeanor conviction was unconstitutional and that resulted in the allegation being dismissed. This relieved the client of his duty to register as a sex offender. I have handled many felony cases of all levels of difficulty and I am very well versed in the strike laws as well as how out of state strikes can be challenged when the prosecution tries to apply them to a California felony. Additionally, I help many people clean their record of prior convictions. Many marijuana felonies are now reducible to misdemeanor as well as many felony simple drug possession charges. Since 2015, California has greatly expanded a person's ability to clean their criminal history. Most recently, California has instituted a process for some to remove themselves from sexual registration per PC 290. I have successfully defended numerous misdemeanor DUI appeals. Assist other fellow misdemeanor and felony attorneys with legal research regularly. I am a listed Contributor to California Drunk Driving Law, James Publishing, by Paul Burglin, Barry Simons, and Ed Kuwatch

Best Lawyer Ever!!!

I was wrongfully accused in a DV case in Clearlake, California which is not a easy situation to get out of as I soon found out , some how ? However, after meeting Bill (as we call him), I knew in two words that he was a down to earth and empathetic human being and that at the same time meant business. He explained everything just like it was with no false promises. I liked that! (Who wouldn't?) Most of all, I didn't know how but I knew I was going to be ok. He even has an investigator at his disposal and they all worked around the clock for my rights. Bill fought for me tooth and nail like I was his son, and I definitely take my hat off to my Lawyer William Conwell for my Freedom, my education and the well being of me and my family. A million thanks to Bill for fighting for me. Jail is not a place anyone wants or needs to be if innocent. I highly recommend this Lawyer and his partners at his Law Office and practice.

Junvenile case

Bill is an open minded person, and will keep you informed about your case. He has a very calming temperment, which makes it a little easier when he has to tell you something you really don't want to hear. He took our case on a last minute situation, and has been there for us all the way. We are still fighting our case, but because of his calm and straight forward personallity, he has been very easy to work with. He is dedicated to your cause, and works extreamly hard on researching what can and can't happen. Knowing all the facts, good or bad, is always helpfully so you are prepared for what every happens in court. He is patient, even when your not, but has a way of calming you down,. Bill sets the bar high for other attorneys' to follow. I highly recommend him.

Amazing Attorney

I had the best experience with Attorney Conwell. When no other Public deffenders wanted to check into case studies I was inquiring about Attorney Conwell went above and beyond. He not only checked, he had copies of the information I was inquiring about. Even as a public defender this man's hard work, determination, and integrity, far surpassed my expectations. I would definitely recommend Attorney Conwell to all. He's guaranteed to work hard for your case!

DUI

Excellant job. Got DUI charges dismissed as CHIP had no probable cause to pull me over. Bill keep me informed, was easy to call, and I only had to attend one hearing. Well worth the $ 1500.

Professional And Honest

William Conwell gave me great consultation and advice. He was honest and upfront about the whole situation and unfortunately could not help me with my case to go after a company for fraud. In the consultation he was attentive and answered questions and if he did not know an answer he clearly stated he did not as he did not want to give false information or steer in the wrong direction, which I appreciated. It was due to his professionalism that I have recommended him to the type of cases he does handle, which are criminal defense cases.

Did a GREAT job for me

Mr. Conwell took on the L.A. County bureaucracy , fought through their red tape, and ignorance, and won for me. The only attorneys that would touch this case wanted to get rich. William Conwell was my HERO in a time that I needed one.

Posted by James | August 16, 2011

A God of Law

Mr. Conwell is one of the most knowledgeable and brightest legal minds I have ever known. His expertise in the legal profession spans not only representation of his clients at the Superior Court level but if necessary at the Appeals Court level too. This is an attorney who not only represents his clients but sets precedents for others to follow. He is not a large law firm attorney with a huge staff to do his work for him but instead a grass roots attorney with a sharp mind that allows him to defend his clients with the best possible outcomes. If you need an attorney who will defend your case and fight for what is right then this is that attorney. I have great admiration for this legal wizard and would recommend him to anyone who needs legal representation or consultation. I sincerely hope that someday this attorney becomes a judge as the justice system will be a better place for having him. Don't make a mistake in choosing another attorney when this one is the best.

DUI case dismissed

My DUI case in Lakeport occurred on 3/29/2009. I switched attorney on 1/31/2011 when I signed up for the services of Mr. Conwell. Exactly 2 years from the date of my DUI arrest, on 3/29/2011, Mr. Conwell was successful in getting my DUI case dismissed (it was originally set to go to trial on 4/11/2011). Mr. Conwell is a man of integrity and he was very good in keeping me posted of all the happenings and upcoming events of my case. I strongly recommend the services of Mr. Conwell.

Very Professional

I hired Bill after I was going through a long a drawn out court process that was never ending! After one hearing I was able to get resolution. He is very patient and listens to your concerns and simply wants to help! I am very grateful for his help and the way he was able to "simplify" a complicated mess. Thank you!

Mark Mcbride

Violent crime Attorney | Aug 31
Relationship: Fellow lawyer in community

"I endorse Bill without reservation. Bill's a real warrior. Bill and I have helped each other out over the years on serious criminal cases by sharing ideas and documents. Bill routinely tries cases where the sentencing exposure is 20 years-plus. But you wouldn't hear that from him; he's that humble. Bill's a whip smart, quiet assassin. I can vouch personally for Bill's work-product and trial skills. I only review people I know personally and for whom I'm able to vouch for their work in a true, substantive way. Such is the case with Bill. He's a man about his business, and he has my respect -- and the respect of the bench and bar statewide. Just an all around great guy and truly competent criminal defense attorney."

"I have observed Mr. Conwell in various courts, and on numerous occassions, for the last 2 and 1/2 years. He is an exceptional attorney who comes to court well prepared, having researched the legal issues that will be argued. Many times I have seen the judge continue matters, as Mr. Conwell presented arguments that the judge was not even familiar with and had to go research himself. Mr. Conwell puts 110% into representing his clients. I have seen him go above and beyond the call of duty numerous times. I have even observed him step in and help an unrepresented person in court, just out of his concern for justice. Mr. Conwell is thoroughly versed in all criminal defense, including misdemeanors, felonies, and DUI's and I would not hestitate recommending his services to anyone."
