About Griesing Mazzeo Law

Griesing Mazzeo Law, LLC, is a full-service women-owned and operated law firm based in Philadelphia, Pennsylvania with satellite offices in Arizona, Florida, New Jersey, New York, and Ohio. We are proudly certified as a woman-owned business by WBENC, enabling us to tackle opportunities specifically intended to promote diversity and inclusion in the legal profession.

In January 2010, during one of the roughest economic downturns across all sectors, we launched our firm with only a handful of clients out of an 800 square foot sublet space. Today, our original three-person team has grown into a team of 11, including 7 lawyers. We have grown from our initial client base to handling 1k+ matters for 500+ clients, including Fortune 500 companies, small and privately held businesses, nonprofits, government entities and individuals. Our clients come from a broad array of industries, including academia, arts and entertainment, chemical, communications, financial services, foodservice, government, insurance, e-commerce, manufacturing, non-profits, pharmaceuticals, professional services, real estate, retail, and technology. Our team is licensed to practice law in Arizona, District of Columbia, Florida, Kentucky, New Jersey, New York, Ohio, Pennsylvania, and South Carolina.

Our lawyers are AV rated and have experience working in house, serving in government and as senior lawyers at top Am Law 100 firms. We are highly sought speakers and respected authorities in our areas of expertise, frequently acknowledged by our peers and clients for top-notch service and results. Our team has received many accolades for professional achievement and civic leadership including: Best Lawyers, Chambers & Partners, Super Lawyers, Client Choice, Pennsylvania’s Best 50 Women in Business, Philadelphia Inquirer’s Influencers of Law Lifetime Achievement Award, Philadelphia Business Journal’s Women of Distinction, Philadelphia Business Journal’s Best of the Bar, American Bar Association’s Excellence in Legal Writing Award, The Legal Intelligencer’s Lawyers on the Fast Track and many others.
