Editor's Review

VerifiedLawFirms editorial

Focus and practice areas

The firm works mostly in environmental law, paired with litigation and with municipal and land use practice. Sive, Paget & Riesel, known on its own materials as SPR, is based in New York City. In my opinion the list of stated practice areas shows a firm that works where development and environmental regulation meet.

The published areas cover environmental impact review and permitting, hazardous substances remediation, and zoning, land use, and municipal law. The firm also names offshore wind, construction, project finance, climate change and resiliency, and renewable energy. Environmental issues in transactions and real estate management complete the set. The breadth here stays inside one field, which is environmental and land use law.

What the litigation covers

On the courtroom side, the firm prosecutes and defends Superfund cost recovery actions. It handles oil spill cases and toxic tort cases, and it takes on challenges to environmental reviews.

These are technical disputes. Superfund cost recovery actions turn on who pays to clean a contaminated site, and they often pull in several responsible parties arguing over their shares. Toxic tort cases link a claimed harm to an exposure, so they lean on scientific and medical evidence. Work of this kind asks a firm to be at ease with regulators and with the witnesses who testify on technical points.

Challenges to environmental reviews are their own category. A party may argue that an agency skipped a required study or leaned on a thin record, and a court then weighs whether the review met the legal standard. Cases like these overlap with the permitting work the firm also handles, so a lawyer can move between the two.

The transactional and regulatory side

Away from the courtroom, the firm prepares environmental assessments and Environmental Impact Statements. It works on Brownfield redevelopment projects, environmental permitting, and due diligence reviews and risk assessments that support corporate transactions.

An Environmental Impact Statement follows a set procedure. A lead agency reviews a proposed project, the public comments on it, and the document studies the effects and the alternatives before any approval. Brownfield redevelopment applies to sites with known or suspected contamination, where cleanup and reuse advance together under state oversight. Matters like these reward a firm that reads both the science and the statute.

Energy and infrastructure projects

The firm lists offshore wind, renewable energy, project finance, and climate change and resiliency, which cluster around big build projects.

These projects follow a similar path. A developer needs land use approvals, then environmental permits, then financing that depends on both. Offshore wind adds federal and state review to that chain, since the seabed and the connection to shore fall under different authorities. A practice that lists all of these areas can handle the zoning questions, the environmental permits, and the review that financing depends on.

How the team is built

The firm organizes its attorneys as principals, associates, senior counsel, and of counsel. That structure puts senior and junior lawyers on the same matter, which suits work that mixes strategy with heavy document review. It also lets the firm staff a large regulatory matter without pulling in outside help.

SPR states that its attorneys include former federal prosecutors and governmental litigators. Lawyers who have worked inside government often know how agencies reach decisions, and that knowledge helps when a case turns on a permit or a review.

The site names twelve principals: Michael Bogin, Mark Chertok, Dan Chorost, Jennifer Coghlan, John-Patrick Curran, Pamela Esterman, Scott Furman, Katherine Ghilain Trudell, Meg Holden, Elizabeth Knauer, Joyce E. Kung, and Christine Leas. A group of that size in a focused field points to depth across the practice areas the firm lists.

Who the firm represents

The client list spans state and local governments, public authorities, and corporations. It also includes cultural and medical institutions, professional sports organizations, developers, and individuals.

That mix matters in environmental work, where a government body, a developer, and a neighbor can each be on a different side of the same permit. A firm that represents clients across those roles builds a working sense of how each one approaches a dispute.

The place of cultural and medical institutions and professional sports organizations on the client list is worth a note. These clients often own or develop large properties, so environmental and land use questions come with the territory. Representing them means handling real estate, construction, and remediation issues together.

What the record shows

The firm states that it has practiced for over sixty years. Long tenure in one field of law usually means a steady flow of similar matters and client relationships that renew across projects. For a client, that kind of continuity can matter as much as any single result.

The website carries a 2026 copyright, and the firm operates from New York. As a reviewer, I read the pairing of a long tenure with a tight practice focus as a sign of a firm that chose its ground and kept to it. The public facts place that ground in environmental law.
