Susan Hamsher is an attorney with significant experience providing a broad range of legal advice to nonprofit organizations in private practice and in-house at one of the world’s largest charities. She excels at incorporating complex legal requirements into effective and practical solutions to advance the strategic business objectives of her clients.

Prior to joining the Tenenbaum Law Group, Susan was a senior associate at a boutique law firm in Washington, DC with a partial focus on the laws governing lobbying and election-related activity by tax-exempt organizations. Susan also advised the firm’s clients on establishing and securing federal tax exemption, governance, fundraising regulation, and the laws applicable to organizations engaged in public interest, policy advocacy, and political activities. In addition, she assisted the firm’s nonprofit clients with corporate partnerships, licensing agreements, and privacy policies, among many other legal issues.

Prior to that, Susan worked as an in-house attorney for over eight years at The Nature Conservancy.

In this role, she worked with local counsel to support a new and rapidly growing program on corporate formation and governance, anti-corruption, fundraising, employment, and contracts and grants review. She also advised the India team on U.S. tax issues such as private benefit and private inurement, how to work with for-profit companies, and conflicts of interest.

Susan has a broad understanding of nonprofit legal matters as well as business operations, governance, and development. She has developed multiple systems to ensure organizational compliance including lobbying expense tracking and timekeeping systems, filing schedules and calendars, and a wide range of policies and procedures. In addition, Susan served as Co-Chair of the Nonprofit Organizations Network for the National Capital Region of the Association of Corporate Counsel from 2017-19.

Before beginning her legal career, Susan held a range of positions in government and public interest organizations.

Tenenbaum Law Group PLLC has been “ranked” by the prestigious U.S. Legal 500 for 2022 in the national Not-for-Profit category. One of only 19 law firms ranked nationwide and the only boutique firm, this is a highly coveted, distinguished honor. TLG Managing Partner Jeff Tenenbaum is also one of only five members of the U.S. Legal 500 Not-for-Profit Hall of Fame. Details can be found here and here.

Here are excerpts from the published client testimonials:

“This is the most responsive legal firm that I have worked with in my career. They are quick to respond and quick to provide work product. Some firms tend to ramble, but not the Tenenbaum Law Group. They listen to our concerns and provide clear, concise responses.”

“Jeff and Nisha are an incredible team – they get how their work impacts their clients – not just legally, but operationally and financially as well.”

“Jeff Tenenbaum is a leading expert in non-profit law. He is extremely knowledgeable and responsive to client questions and concerns.”

“Jeff Tenenbaum and his team are exceptional partners for associations in their legal and governance needs. Tenenbaum is smart, practical, and easy to work with.”

“TLG is extremely responsive and gets work done quickly. Jeff Tenenbaum has a very practical, real-world approach to solving problems, which makes him a pleasure to work with.”

“Tenenbaum Law Group didn’t miss a beat during COVID-19, despite an increased workload with event cancellation negotiations, PPP loan questions, and Employee Retention Tax credit questions. They provide expertise in the not-for-profit industry and during the last year have provided informed advice regarding a range of issues including COVID-19 specific issues, bylaws, and board governance, filing an Amicus Curiae Brief, and hotel negotiations.”

In addition to other honors and recognitions, in its first year of existence, TLG was awarded the (top) Tier 1 designation in the Washington, DC metropolitan area for Nonprofit/Charities Law for 2021 by Best Law Firms/U.S. News & World Report®, and then again for 2022.
