Donald P. Gallo is a highly regarded environmental advocate dedicated to serving clients across Wisconsin from his office at Gallo Law, LLC, in Hartford. With a wealth of experience spanning more than three decades, he has successfully navigated complex cases involving waterway permits, air quality permits, hazardous waste compliance and various transactional matters. His commitment to environmental protection and legal knowledge makes him a trusted resource for individuals and organizations seeking guidance in these critical areas.
Successfully assisting owners and developers in legal proceedings, Mr. Gallo counsels them in brownfield development projects, securing state and federal grants, zero-interest loans and insurance coverage for environmental cleanups. He has also managed hundreds of petroleum convenience stores, bulk plants and terminal cleanups. Additionally, he has overseen 78 dry-cleaning solvent cleanups, including 38 Department of Natural Resources-closed sites, alongside numerous industrial cleanups, expansions, redevelopments and environmental regulatory compliance matters.
Holding a Master of Science in civil engineering from The University of Akron, Mr. Gallo brings a strong technical foundation to his practice. He effectively bridges the gap between complex engineering concepts and the law. He received his J.D., cum laude, from Marquette University Law School. A dedicated practitioner, he has been licensed to practice law in Wisconsin since 1990.
Genuinely committed to protecting the environment, Mr. Gallo uses his background to make a real difference. He understands both engineering and law, which allows him to help clients design greener projects and strictly follow environmental laws.
