Springer Ayeni, A Professional Law Corporation is an AV Preeminent-rated San Leandro disability insurance law firm founded by nationally recognized ERISA litigator Cassie Springer Ayeni, advocating for employees whose long-term disability and life insurance benefits have been wrongfully denied by major insurers.

Elite ERISA and Long-Term Disability Advocacy in San Leandro

When a severe medical condition prevents you from working, employer-sponsored disability insurance is supposed to provide essential income security. Yet, insurance carriers frequently deny, delay, or terminate valid claims using biased physician reviews and procedural traps. Springer Ayeni, A Professional Law Corporation, located at 123 Estudillo Ave Suite 201 in San Leandro, California, is one of the premier employee benefits law firms in the nation. Founded in 2002 by attorney Cassie Springer Ayeni, a graduate of the UC Berkeley School of Law, the firm is dedicated exclusively to fighting wrongful benefit denials under the Employee Retirement Income Security Act. If you need an employment and labor lawyer to battle insurance conglomerates in federal court or reverse an administrative denial, Springer Ayeni delivers formidable, proven advocacy.

Targeted Representation in High-Stakes Disability and Benefit Disputes

Unlike general practices that treat benefits law as a sideline, Springer Ayeni focuses exclusively on ERISA benefit litigation and administrative appeals. Operating as top-tier employment and labor lawyers, contract lawyers, and business litigation lawyers, Attorney Springer Ayeni handles complex disputes against major insurance companies such as Unum, MetLife, Hartford, Lincoln, and Sedgwick:

  • ERISA Administrative Appeals: Building an airtight medical, vocational, and factual evidentiary record during mandatory administrative appeal stages, creating the leverage needed to overturn wrongful insurance denials before litigation.
  • Federal Court ERISA Litigation: Filing aggressive federal lawsuits under 29 U.S.C. Section 1132 to recover withheld monthly disability benefits, enforce plan terms, and obtain statutory attorney fee awards.
  • Individual and Group Long-Term Disability: Representing physicians, tech executives, attorneys, and corporate professionals suffering from cognitive impairments, chronic illnesses, and musculoskeletal trauma.
  • Long COVID and Complex Medical Claims: Championing disability benefits for claimants disabled by post-acute COVID-19 sequelae, autoimmune disorders, chronic fatigue syndrome, and fibromyalgia.
  • Wrongfully Denied Life Insurance Claims: Recovering life insurance proceeds wrongfully withheld due to employer administrative oversights, premium payment discrepancies, or alleged non-disclosure issues.

The Springer Ayeni Advantage: National Authority and Contingency Fee Representation

Clients hire an attorney at Springer Ayeni because Cassie Springer Ayeni is recognized nationwide as a leading authority in ERISA litigation. An AV Preeminent-rated attorney by Martindale-Hubbell and regularly named to the Top 50 Women Northern California Super Lawyers and Best Lawyers in America, she has authored definitive treatises on employee benefits law for the American Bar Association. The firm takes pride in constructing comprehensive claim files that compel insurers to reverse their own decisions. Cases are handled on a contingency fee arrangement, meaning clients pay no attorney fees unless benefits are successfully secured or restored. When you find a lawyer with this specialized proficiency, you level the playing field against billion-dollar insurance institutions.
