Tenenbaum Law Group One of Only a Small Handful of Law Firms to Receive 2026 Tier 1 Washington, DC Designation by Best Law Firms® for Nonprofit/Charities Law
November 6, 2025
The Tenenbaum Law Group (TLG) is very proud to have once again been awarded – in its fifth year – the (top) Tier 1 designation in the Washington, DC metropolitan area for Nonprofit/Charities Law for 2026 by Best Law Firms®. This is the fifth year in a row that the firm, founded in January 2020, has received this Tier 1 designation. TLG is one of only a handful of law firms in the Washington, DC region to have received this distinguished 2026 honor in Tier 1 (there were ten total firms in the three tiers combined) – and one of only two boutique firms among the ten. The law firm rankings are the result of a rigorous and highly regarded peer-review process, with input solely from other attorneys in the nonprofit sector. In addition, TLG’s Managing Partner Jeff Tenenbaum was, once again, awarded the Best Lawyers® designation for 2026 for Nonprofit/Charities Law nationally, an honor he has received every year since 2012.
