Representative Cases

  • Andrew helped clients sell their business to a well-known corporation for an 8-figure purchase price. He negotiated the terms of the acquisition, drafted legal documents, and completed the deal, which involved many disclosures and a complex legal framework, in a timely manner.
  • When a business owner’s relationship with his partner went sour, the fallout threatened the productivity of the company, which had millions of dollars of revenue annually. Andrew negotiated a buy-out of the partner, and drafted its legal framework. The buy-out contained terms that enabled Andrew’s client to consolidate all ownership in himself, with manageable payments that allowed the business to continue operating without skipping a beat.
  • Andrew helped a business create a sophisticated Executive Compensation Plan that enabled the business to incentivize high level employees by offering many of the benefits of equity ownership, such as profit sharing and bonuses upon certain events, without actually transferring stock ownership.

  • Andrew helped clients transfer significant wealth to the next generation in a way that minimizes exposure to death taxes.
  • Andrew advised an elderly client and her family on the legal aspects of long-term nursing home care, including methods of payment, proper use of assets, and qualifying for Medical Assistance.

  • Andrew counseled a client on a will, durable power of attorney, and advance healthcare directive, and he completed the documents on an emergent basis prior to the client undergoing a serious surgical procedure.
