Illana Leiser focuses upon estate administration, litigation, and matters involving complex financial issues and investigation.

As an attorney with a finance background, Illana Leiser approaches the practice of law from an analytical perspective. This can be especially useful in litigated estate and trust matters involving alleged fraud or mismanagement of assets.

Ms. Leiser transitioned into law after more than a decade in finance, during which time she worked at highly regarded firms, including Neuberger Berman and Federated Investors. She is a Chartered Financial Analyst (CFA) and Certified Financial Planner™ professional (CFP®). These designations require rigorous educational requirements, testing, proven experience, and a strict code of ethics.
