She is an incredible attorney and person, and deserves a lot of recognition.”

ERISA Benefit Claims

Most private employer-sponsored disability benefit plans are governed by the Employee Retirement Income Security Act (ERISA), a complex area of law that requires expertise for success. Cassie has developed unmatched expertise in this area.

Long-haul COVID Disability Claims

Long-haul COVID patients may experience a range of CDC-recognized symptoms that can prevent them from working. Cassie has quickly developed expertise in the area, presenting to long-haul COVID survivors through Body Politic’s long-haulers network and being quoted in The Wall Street Journal.
