The attorneys of The Margiotta Law Firm, P.C. have handled several high profile cases including Simba, the service dog who received national attention after the Cave family who owned him filed a $150 million lawsuit against their hearing-impaired son's school district for banning Simba from the premises. Simba was banned on the grounds that the dog's presence was contrary to school policy and might pose health risks to staff members and students who have allergies to dogs.

In August of 2009, Mr. Margiotta announced he is seeking $100 million in damages for his client, Officer Jeff Colletti, claiming Officer Colletti's civil rights were violated when he was denied a leave of absence to care for his sick wife and newborn child, and that his client should have been entitled to take time off under the federal Family and Medical Leave Act.
