Not for title IX issue

I hired Bill to handle my title IX case because he said he knew how to fight for me. At the beginning, he promised me to handle my title IX for a flat fee of $5000. Apparently, he had very few experience in handling title IX case. After several interactions with the title IX investigator, he realize...d that $5000 could not cover his labor and changed this fee method to hourly rate. Then, I realized that he did not know about title IX and I was his white mice for his probably very first title IX case. Overall, not very pleasant experience because he barely knew title IX but pretended to know at the beginning.

The best attorney you in the world!

Bill has been my criminal attorney for a year and a half now.  I was arrested, bailed out and called Bill's office more than a year ago.  Cathy answered the phone and I was distraught.  I did something out of desperation which added to an already mile long list of white collard felonies.  Cathy was a... bundle of information and put me at ease upon my release.  I retained Bill to watch my case and nothing was filed for 6 months.  Just when I thought I was safe, Bill called me to advise me the D.A. filed.  He really did watch the progress of my investigation.  Every other month I went to court for over a year and watched Bill maneuver my case through the system to get the right D.A., to put me in the right spot light, to request time for this document or that document....I went to counseling, I got doctor notes, I got supportive letters from my employer, my family members...anything he asked to do - I did!  He said have faith.  Putting your life in someone else's hands is the hardest thing to do.  But, I did.  And I could not be more thankful, grateful and happy.  Bill and Cathy are amazing.  The best!  When anyone I know or any loved one I know needs any legal help - I will always recommend William Weinberg.  He is the Best!

Highly Recommend William Weinberg

If you need an honest and hard working attorney, I would highly recommend William Weinberg. Mr. Weinberg spent considerable time advising me on the approach to take to resolve my case successfully. He then negotiated with the DA’s Office to have my case dismissed. He and his staff are the consumma...te professionals and very easy to work with. But most importantly, Mr. Weinberg will work very hard to get you the results you want.

Petition for Factual Innocence Granted, Thanks to Mr. Weinberg!

I was staying in Orange County for business for a couple of months, within which I managed to get no tan, a $300 dollar jay-walking ticket, and an arrest with felony drug charges! The charges stemmed from my having legally prescribed medications in an unmarked container on my key ring, along with a ...bad attitude (which I should have kept under control) with the arresting officers. At my arraignment, I produced records of the prescriptions, and immediately the DA dropped the charges. I was thrilled. Fast forward a year, and my new landlord asks me about this felony drug arrest in California. Even though the charges were dropped, the arrest was still on my record and looked horrid. Due to quantity, they were felony drug dealing charges. I contacted Mr. Weinberg in order to determine whether or not there was anything I could do in order to get these charges erased from my permanent record. Mr. Weinberg promptly returned my call, and gave me the run-down of what we would need to do. He did not promise me anything other than that he would file the necessary paperwork and try his best to get a Petition of Factual Innocence granted in order to seal the arrest from being something I would have to deal with every time a background check was made on me in the future. I was many states away and very busy, so I was grateful to have someone else working on this on my behalf. The fee was not cheap, but compared to having this on my record, and not having to deal with this issue myself, his fee was a bargain. I mostly dealt with Cathy Ciuffetelli, his assistant, who kept me up to date and answered all questions I had that came up. Then one day, a few weeks ago, I got a voice mail from Cathy asking me to give her a call back. I call back, and she informs me that Mr. Weinberg was able to get the petition passed! Needless to say, I am more than pleased with Mr. Weinberg's practice (thanks for all your help too Cathy!). I found them both to be very professional and personable, empathizing with my situation and supplying me with all the information I needed. In the end, the product of the work speaks for itself, as Mr. Weinberg was able to accomplish what I needed him to. I also needed someone who would take the ball and run with it, so to speak, as I am a busy individual myself. I did not need to constantly pester them for updates but was able to get immediate responses whenever I had a question. Thanks very much Mr. Weinberg and Cathy!

Client Review

It is not often that I come online to make reviews, but Mr. Weinberg had such an impact on the lives of my family and I that I had to share my experience. My father was facing criminal charges and a divorce at the same time and Mr. Weinberg was instrumental in navigating us through the process. He ha...d an excellent friend who served as our family attorney while Mr. Weinberg guided us on the criminal aspect. His knowledge, expertise and sensitivity towards a case was unmatched. I can speak to this because it was only after being jerked around by other bad attorneys who dont read your documents and who are just after money that I saw the difference. Mr. Weinberg read through everything and we were always so prepared. He'll give you the best advice and has excellent resources and connections available at his disposal. I learned the hard way that not all attorneys will put the time and effort into your case. Dont mess with your future because having gone through this system, the only thing that can help is a good attorney at your side. Once my case was over, Mr. Weinberg answered questions I had on any topic and responded to emails instantly. So nice to know that there are good people out there :)

"Bill is a top-grade criminal defense attorney whom I have known for many years. He is hardworking and highly intelligent. Perhaps what is most impressive about Bill is his proper balance of book and street "smarts." He fully understands the letter of the law, but more importantly, what facts will be most important to a judge and/or jury. Bill comes with my highest endorsement."
