      "She will put your anxiety at ease and get you through the tangled system."
      Diane is the perfect mix of gentle understanding and fierce action you’ll need if you find yourself dealing with the OC court system.
      - Angie T.
      "Whatever you’re going through, I’m confident Diane will achieve the best outcome you could hope for."
      My first impression was that she’s very experienced, no-nonsense, knows the law, how the system works, and was very busy as a result. I quickly realized that she exceeded even those first impressions but also cared very much about my story, needs, an

      "From the start of my case, she has been there for me."
      First of all, I would like to thank Diane for everything she has done for me. From the start of my case, she has been there for me. Only very few people were granted bond and she pulled it off in my case. I know for a fact not too many lawyers could have done that. I am on probation for three years.. while “the others” will not have the chance to raise their children and live their lives. I was headed to prison….I am free.. and for that, I am forever grateful.
      - John H.
      "Diane Bass is a phenomenal attorney."
      After meeting with Diane I felt immediate comfort, and I was sold on the fact that I could trust this amazing person with my life. Diane Bass was there for me every step of the way like no other attorney had ever been.
      - Ryan O.
      "She is not afraid to battle for you. With her, you will never be alone."
      Diane is a brilliant attorney. She listens carefully to your problems and clearly advises you with honesty. She was with me from the first day of my case and I have never been disappointed in any way.
      - Maria K.
      "I highly recommend Diane if you are dealing with legal troubles of your own."
      Since this being my first Federal offense, I had no idea what to expect. I was extremely anxious. After talking to Diane, I felt like she was the attorney I needed to help me get through these challenging times. Her professionalism and knowledge of the law
      - Adam P.
      "Diane’s work is second to none."

      Diane’s work is second to none. I was charged with felony DV, and after working with one firm in Irvine that did absolutely nothing, I did some hard research and found Diane. She worked quickly and diligently and got the case dismissed. I absolutely don’t foresee me needing a criminal lawyer down the road, but if I do, it’ll be Diane hands down!

      - Shadic A.
      "Diane is the most professional, thorough attorney I have ever met."
      Her expertise, connections, analysis, and comprehensive review of my situation were more than I could ever ask. I am extremely grateful and couldn't be happier with my choice!
      - Jeff R.

    Federal Criminal Defense in Orange County

    Federal investigations can begin before formal charges through a target letter, grand jury subpoena, search warrant, agency interview, or request for records. A target letter generally serves as notice that federal prosecutors consider someone a target of an investigation. A grand jury subpoena typically requires testimony or documents for a grand jury investigation.

    Federal matters arising in Orange County are generally handled through the Southern Division of the Central District of California in Santa Ana. The FBI, IRS, DEA, and other federal agencies may investigate allegations before the United States Attorney’s Office decides whether to pursue charges.

    Attorney Bass represents clients in federal matters involving fraud, money laundering, drug conspiracies, tax evasion, and related allegations. Her experience also includes federal cases involving immigration fraud, health care fraud, wire fraud, bank fraud, drug trafficking, and RICO conspiracy allegations.

    Federal procedure can involve discovery, pretrial motions, plea negotiations, trial, and federal sentencing. Federal sentencing generally refers to the court’s process for determining a sentence after a conviction or guilty plea. Early legal guidance can help a person understand how to respond to investigative contact and prepare for the procedural issues ahead.
