The California State Bar web site is located here:
Click on "Attorney Search" and type in the name.
If nothing comes up try a few variants of the name to be sure you are asking for the right information.
Be sure to read any PDF down at the bottom as these show discliplinary proceedings.
If they are not listed then you may want to notify the State Bar of this.
