David also does a significant amount of administrative controversy work, which often involves representation of clients who are under criminal investigation, a civil audit or who have serious IRS collection concerns.

Business and estate planning for entrepreneurs and businesses are also a part of David’s practice. He focuses on minimizing all taxes, including income, estate, gift, GST, and sales/use tax. Taking a more holistic approach to planning, David examines solutions that best serve the client from the myriad of taxation, liability concerns, and other regulatory issues.
