Overview
Greg Schwinghammer is a shareholder who joined Gunster following law school in 1996. Prior to law school, Greg was an officer in the U.S. Army Armored Cavalry, where he served in Germany and Kuwait.
Greg’s practice focuses on complicated litigation: toxic torts, class actions, environmental, and complex business, real estate and employment litigation. Greg is co-chair of Gunster’s Class Action Defense team as well as the Product Liability and Toxic Tort practice group. He represents clients throughout Florida and, when needed, around the country—including a six-week jury trial in Anchorage, Alaska in 2024. Greg has tried cases at all levels — from local administrative hearings, to county court commercial evictions, to arbitration, to jury trials in circuit and federal courts. Greg has spoken on employment and class action issues to various Bar association groups, and has presented on class certification to the Association of Corporate Counsel and as a panelist in front of the Florida Conference of Circuit Judges.
Greg has represented Fortune 50 companies, statewide and local businesses, and high net worth individuals in a wide array of litigation. His experience ranges from mass and toxic tort cases, consumer and employment class actions, complex business and breach of contract cases, labor and employment law claims, and bankruptcy litigation, to name only a few.
Since 2012, Greg has been involved in the judicial nominating process in Florida. He began serving on the Judicial Nominating Commission (JNC) for the 15th Judicial Circuit in Palm Beach County and was Chair for five years. He was then appointed to the JNC for the Fourth District Court of Appeals in 2020, reappointed in 2022, and elected Chair in 2025. Additionally, Greg has served as Chair of a Florida Bar Grievance Committee in two separate terms.
Greg is involved in the community as a member of Leadership Florida (Class 34), as well as serving on the Board of the Education Foundation of Palm Beach County, and for several years has served as coach and board member for the Jupiter Tequesta Athletic Association Girls’ Lacrosse League.

- Pop’s Pancakes, Inc. v. NuCo2, Inc., 251 F.R.D. 677(S.D. Fla. 2008)—Defeated class certification involving a putative class of 36,000 members claiming violations of Florida’s Deceptive and Unfair Trade Practices Act. Plaintiffs alleged they were charged a “hidden” administrative fee as part of a tax, but we demonstrated that the fee was not hidden, and was disclosed on invoices, and further that several members of the putative class were aware of the fee. In fact, in deposition established that the named plaintiffs were aware of the fee, so class certification was denied and the case dismissed.
