The History of The Mark Casto Law Firm, PC

In January 2006, Mark was a founding partner of The Law Firm of Bennett and Casto. Mark's practice focus on injured persons expanded to include personal injury, workers compensation, Nursing Home Neglect and Abuse, medical malpractice and employment discrimination claims.

Ten years later, in April 2016, Mark founded The Mark Casto Law Firm, PC on the premise of providing superior service to his clients. Believing that it is hypocritical to sue medical doctors when also asking these doctors to care for his personal injury and worker's compensation clients, Mark will not file a claim against a doctor for medical malpractice, but rather the hospital or other negligent parties.

Successful Appellate Practice

Mark also has handled numerous cases on appeal. He has argued in person before the Georgia Supreme Court and Georgia Court of Appeals. He has never lost an appeal in which he was allowed to argue in person before the Appellate Judges.

Education Mark earned a B.S. in Sports Management from Western Carolina University in 1991 and graduated with Honors.
