Who We Are
A Personal Injury Firm Built for Serious Cases
Serious personal injury litigation can involve far more than submitting an insurance claim. Important evidence may disappear, several people or businesses may share responsibility, multiple insurance policies may apply, and the long-term consequences of an injury may not be understood immediately.
Marks Law Group, P.C. focuses on developing these cases deliberately from the beginning. That means investigating what happened, preserving evidence, identifying potentially responsible parties, understanding available insurance coverage, and documenting the medical and financial consequences of the injury.
The firm is structured around direct attorney involvement. Harris Marks remains personally involved in the strategy and major stages of litigation rather than treating the attorney-client relationship as a handoff after the initial consultation.
From its physical office in Great Neck, Marks Law Group serves injured people and families throughout Nassau County, Long Island, New York City, and other areas where the firm accepts matters.
How We Work
What Defines Marks Law Group
The firm’s approach centers on four principles that matter throughout a serious personal injury case.
Direct Attorney Access
Clients have access to the attorney responsible for the major strategy and litigation decisions in their case.
Clear Communication
Clients should understand what is happening, why decisions are being made, what the next stage involves, and what information the firm needs from them.
Accountability
Serious cases require identifying the people, companies, property owners, contractors, insurers, or other entities that may bear legal responsibility.
Full Damages Development
The case should account for medical treatment, lost income, future care, earning capacity, functional limitations, and other legally recoverable consequences of an injury.
Trial-Ready Strategy
Preparing a case to withstand discovery, depositions, experts, motions, and trial can create stronger leverage even when the matter ultimately resolves without a courtroom verdict.
Our Litigation Method
The 360° Approach to a Serious Injury Case
A strong claim is not a single demand letter or medical record. It is a connected body of evidence developed throughout the case.
Marks Law Group looks at liability, defendants, insurance, medical evidence, financial losses, future consequences, and litigation strategy together rather than treating them as separate problems.
Preparation is designed to begin before an insurance company has the opportunity to define the case on its own terms.
1
Investigate
Preserve the scene, records, witnesses, video, vehicles, equipment, and other time-sensitive evidence.
2
Identify
Determine the responsible people, companies, owners, contractors, insurers, and potential sources of recovery.
3
Document
Build the medical, economic, vocational, and daily-life evidence needed to establish the full consequences of the injury.
4
Litigate
Use pleadings, discovery, depositions, experts, motion practice, negotiation, and trial preparation strategically.
