You may report your attorney by preparing and filing a complaint which may be found here:
You do not need an attorney to assist you in dealing with the disciplinary board but note that the disciplinary board cannot give you legal advice, so you may want to retain another attorney as a consultant or just speak with an attorney to get their opinion on what happened and what your rights/remedies are.
After you contact the board, they will perform an investigation and, if necessary, meet with you. You will be involved in the entire process though the board will do their best to ensure your confidentiality (and only reveal your identity if necessary).
Depending on what the board has determined , the lawyer may be subject to a public discipline or a private discipline. In the most egregious of cases, the lawyer may lose his/her license.
