After taking on the National Football League on behalf of hundreds of current and former professional football players facing traumatic brain injury, Atlanta class action litigator Mike McGlamry is setting his sights on the nation’s multi-billion-dollar prescription pet food industry.

McGlamry—a member of the plaintiffs’ steering committee in the ground-breaking, $1 billion settlement with the NFL—is joining forces with attorneys in California, North Carolina and Minnesota on behalf of pet owners whom he contends are being duped by veterinarian chains and pet food suppliers and manufacturers into spending unwarranted money on prescription pet foods for their furry companions.
