Gregg concentrates on zealously representing victims of catastrophic injuries. Gregg has spent his entire legal career fighting for severely injured individuals against insurance companies and large corporations. Gregg strongly believes that his job is to balance the scales of justice in a society that often times hinders individual victims from recovering fair compensation against large and powerful special interest groups. In furtherance of these goals, Gregg has tried numerous personal injury cases to verdict and has multiple recoveries in excess of a million dollars. Gregg has obtained substantial recoveries for victims of construction accidents, medical malpractice and injuries caused by unreasonably dangerous and defective products. Gregg believes that the foundation for a successful winning legal strategy is his teamwork with his clients. Gregg takes pride in getting his hands dirty and doing whatever it takes to get the job done.
