David A. Lewis

New York, New York

When a lawyer needs a lawyer, David is the one to call. In most matters of legal ethics and professional responsibility, David provides attorneys and their firms practical advice on issues of disciplinary exposure, financial risk, and conflicts of interest.

An eminent authority on disciplinary complaints, malpractice suits, and the panoply of disputes between lawyers, their firms, and their clients, David's credentials include a three-year term as chair of the New York City Bar Association's prestigious Professional Responsibility Committee. He has also served on the state level, with the New York State Bar Association's Committee on Standards of Attorney Conduct (COSAC). These committees are at the vanguard of the legal ethics field, studying and recommending changes to rules and procedures that directly affect the practice of law.

David's own practice reflects this experience. He represents lawyers and firms wherever the Rules of Professional Conduct come into play - from partnership disputes to privilege and confidentiality issues - from conflicts of interest to bar admission problems. He defends clients in disciplinary matters, disqualification motions and other court matters.

David is quick to make the distinction between ethics and morality. He understands that one's morals are not always an accurate guide to what the ethics rules proscribe.

To help lawyers grasp this distinction, David advises both outside and inside counsel - including Fortune 500 companies - on issues of ethical risk management. At his lectures and seminars, he teaches how to avoid disciplinary complaints and malpractice charges - to make sure engagement letters, conflict waivers, and other basic procedures are scrupulously executed in a way that reduces exposure. Prevention, to David, is always preferable to litigation.

David's approach to legal ethics - a field known for its rigidity, is to keep an open mind. He prefers to think through his client's entire situation, looking for other - possibly better - options than what is immediately evident.

For his clients - those lawyers and firms that may have strayed from the rules, thereby putting their careers and businesses at risk - David's thorough and carefully considered approach provides the guidance that puts those clients on the right track.

Legal Ethics Presenter

As a nationally recognized legal ethics speaker, David is often called upon to participate in programs dealing with complex legal ethics and compliance issues. These ethics programs include programs sponsored by: Practicing Law Institute, American Bar Association, New York State Bar Association, New York City Bar Association, the New York County Lawyers' Association, Association for Professional Responsibility Lawyers, Fortune 500 companies and various national law firms. At many of his lectures and seminars, David focuses on teaching how to better foster a culture of ethical compliance, enhance awareness and improve training from top to bottom.

David has also been honored to serve as an adjunct law professor teaching legal ethics and professional responsibility.
