About Us

Now accepting clients in all 50 States, Puerto Rico & the U.S. Virgin Islands


The Law Offices of Lilli W. Marder, Esq. was founded on the principle that every claimant has the right to be represented by a qualified attorney, during every step of their claim. “You have the right to an attorney” has significant meaning for Social Security disability claimants; especially those who are too weakened by their disability to participate in this often lengthy process of claiming Social Security benefits. The right to have your case heard before the Social Security Administration is the very same right we have been defending for our clients since we opened the doors of our first office in South Florida in 1990.
  • Our founding partner, Lilli W. Marder, began her career working for the Social Security Administration where she developed a strong interest in the field of Disability Law. After years of experience handling the legal aspects of Disability and Social Security cases from the Social Security Administration’s side, she retired from her government position and started her own practice. Out of this single office has grown three fully staffed offices serving claimants nationwide, with two in South Florida; Miami and Boca Raton, along with our Puerto Rico office located in San Juan.
  • Our offices have been pioneers in the field of Social Security Law. We make great efforts to stay at the forefront of the changes in Disability Law and Social Security Procedure; utilizing state of the art practices and technology to insure a smooth changeover into the new electronic disability system.
