Diane Seltzer is admitted to all state and federal courts in the District of Columbia and Maryland, as well as the U.S. Court of Federal Claims and the U.S. Courts of Appeals for the District of Columbia Circuit,  the Fourth Circuit, and the Federal Circuit.  

For 2020 and 2021, Diane Seltzer was peer rated as a Maryland Super Lawyer and as a Washington, D.C. Super Lawyer through Thomson Reuters.  In a 2019 survey conducted by Bethesda Magazine, her peers selected her as one of the area’s Top Employment Law attorneys. 

Diane Seltzer was elected to the Board of Governors of the D.C. Bar for the 2021-2024 term after serving as its Secretary for the 2020-2021 term.  She was also appointed Vice-Chair of the American Bar Association’s Solo, Small Firm & General Practice Division’s Litigation Committee for its 2021 term and was reappointed for its 2022 term.

Ms. Seltzer serves as a mediator for parties facing employment disputes.  Because she represents both employers and employees, she is uniquely qualified to understand each of their perspectives. She utilizes this insight during mediations and thus is not perceived as being biased towards one side.

Ms. Seltzer has served as an Adjunct Professor of Law at American University Washington College of Law’s (WCL) since 2003. She has taught “Employment Discrimination” and “Employment Law: The Employment Relationship” to upper level law students. She is on the Faculty Board of the American University Washington College of Law Labor and Employment Law Forum.

Ms. Seltzer is an avid volunteer with the D.C. Bar, which has over 110,000 members and is the largest unified bar in the United States.  She currently serves on the D.C. Bar’s Continuing Legal Education (CLE) Committee and previously served as Chair (2016-2017), Vice Chair (2015-2016), and Committee member (2012-2015).  The CLE Program of the D.C. Bar offered 218 courses in FY 2019-2020 that were taught by over 500 volunteer faculty.  Over 7,500 lawyers attend these courses annually, and all courses fulfill mandatory/minimum accreditation requirements of the 46 states that have such requirements. Ms. Seltzer teaches numerous courses each year for the D.C. Bar’s CLE Program.

Ms. Seltzer served on the D.C. Bar’s 2020-2025 Strategic Planning Committee.  Since 2018, she has also served on the D.C. Bar’s Screening Committee, which makes candidate recommendations to the Board of Governors; the Communities Committee, which oversees the D.C. Bar’s 20 Communities (formerly Sections); and the Nominations Committee, which elects nominees for the D.C. Bar President-elect, Secretary, Treasurer, Board of Governors, and members of the ABA House of Delegates.

Since 2004, Ms. Seltzer has worked with two other attorneys to provide annual employment discrimination law training to all of the federal judicial law clerks in Maryland.  In January 2016, the Judges of the United States District Court of Maryland awarded her their Exceptional Service Award.  The federal Judges thanked her for her ongoing service to the Court by presenting her with this award and by asking her to continue to provide annual employment discrimination law training to their law clerks.

Diane Seltzer currently serves on the Steering Committee of the National Capital Region’s 9/11 Memorial Stair Climb. Hosted by the Prince George’s County Fire/EMS Department, the Stair Climb is a way to honor and remember the FDNY firefighters who gave their lives on September 11, 2001. Each participant pays tribute to an FDNY firefighter by climbing or walking the equivalent of the 110 stories of the World Trade Center. The granddaughter of an FDNY Lieutenant, she takes immense pleasure in assisting firefighters, EMTs, and police officers in obtaining, or being reinstated to, positions from which they were unlawfully prohibited from holding due to their disabilities, religious beliefs, gender, prior EEO activity, and other protected characteristics. In July 2010, Diane Seltzer became certified as a Maryland Emergency Medical Technician (EMT-B) and served until June 2012 as a volunteer with the Glen Echo Fire Department in Bethesda, Maryland.

In July 2019, Diane Seltzer accepted the invitation of Free Mom Hugs to serve as its Chapter Leader for the Washington, DC chapter.  Free Mom Hugs is a registered non-profit organization made up of parents and allies of the LGBTQ+ community.  The organization is dedicated to affirming, celebrating, and advocating for equality for the LGBTQ+ community.

From 2004 until 2006, Ms. Seltzer served on the Board of Directors of National Capital Housing Management Corporation, a non-profit organization that provides and promotes affordable fair housing for senior citizens and disabled adults of low to moderate income.
