  • Structuring the legal and financial relationships in “tandem” combined for-profit, non-profit ventures

  • Establishing joint ventures, strategic partnerships and co-ventures between businesses, family offices, funds, investors, and nonprofits

  • Separating non-profit commercial enterprises into for-profit businesses

  • Structuring socially responsible investments, including program-related investments and mission-related investments

  • Setting up benefit corporations, social enterprises, nonprofits, micro-franchises, and their respective operating agreements, filings, and registrations


  • Development of a for-profit socially responsible business that partners with federal programs to hire up to 50% of its workforce from a population of former substance abusers and formerly incarcerated persons, giving a “second chance” to people who are otherwise largely unemployable. The business has been very successful and is now in its third round of financing.

  • Structuring the successful spin-off of a for-profit enterprise by a nonprofit. The parent nonprofit developed medical equipment for use in rural clinics of developing countries. The organization began by selling equipment to foundations who placed the equipment in clinics they were supporting outside of the U.S. However, other markets and customers came forward, and the company needed the freedom to grow independently. After separating from the parent nonprofit, the business has grown successfully, and the profits have been used to support the parent nonprofit’s mission.

  • Structuring a PRI for a private foundation, including term-sheet negotiation. Performing due diligence, drafting deal documents, and all steps to closing - the investment was successfully completed, and the company is growing its impact and finances.


Prior to founding Bromberger Law, Allen was a Partner at Perlman & Perlman for 14 years, and also served as President of Power of Attorney, a private operating foundation in New York City, and Executive Director of Lawyers Alliance for New York, a public interest law firm. From foundations and family offices to funds and entrepreneurs, Allen offers counsel and serves as a trusted advisor and connector for his clients. Allen’s ambition is to build legal support for social benefit that will thrive for years to come. Engage with Allen on LinkedIn or Twitter.
