Communities Served

At The Law Office of Mark A. Siesel, we understand that personal injuries can happen anywhere, at any time, and in any community. With almost 40 years of experience representing clients in personal injury cases throughout White Plains and beyond, we have built a reputation for delivering dedicated legal guidance while creating lasting relationships.

We are proud to serve individuals across Westchester County and the lower Hudson Valley, handling cases ranging from motor vehicle accidents to brain injuries, premises liability, dog bites, and DWI matters. If you or a loved one has been injured, schedule a free consultation to review your potential case and to understand your legal options.

Serving Your Community with Personal Attention

Every community has unique roads, workplaces, and neighborhoods where accidents can occur. That’s why our firm emphasizes a personal approach. At The Law Office of Mark A. Siesel, we return calls and emails within 24 business hours, often the same day, ensuring you never feel ignored or left in the dark. Our goal is to give you the support you need during a stressful time.

Whether you are dealing with a serious motor vehicle accident, a DWI charge, or a catastrophic injury such as a traumatic brain injury, you deserve a lawyer who listens, investigates thoroughly, and provides guidance that reflects nearly four decades of experience.

Motor Vehicle Accidents

Car, truck, and motorcycle accidents are among the most common cases we handle. Injuries can range from minor soft-tissue trauma to life-altering spinal or brain injuries. Navigating insurance claims, medical documentation, and legal procedures can be overwhelming, but we make it manageable.

When evaluating a case, we carefully review critical factors, including:

  • The insurance coverage of the responsible party, including umbrella or excess policies
  • Potential supplemental underinsured motorist coverage
  • Available assets of the tortfeasor for larger claims

Our approach ensures that you pursue maximum available compensation for pain and suffering, past and future medical expenses, loss of earnings or earning capacity, and related costs, including property damage, car rentals, and other incidental expenses.

DWI and DWAI Cases

If you are facing a DWI or DWAI (driving while ability impaired) charge, the stakes can be high. In New York, DWI and DWAI charges can affect your driving privileges, insurance, and criminal record.

Traumatic Brain Injuries and Catastrophic Injuries

Traumatic brain injuries (TBI) can result from a single incident, such as a car accident, slip and fall, or a workplace injury. These injuries can profoundly impact your life and your family’s future.

We have almost 40 years of experience representing clients with brain injuries, ensuring that every aspect of your case is thoroughly documented. This includes medical records, expert evaluations, and an analysis of long-term care and rehabilitation needs. Our approach focuses on obtaining compensation for the areas that matter most: pain and suffering, medical expenses, and loss of earnings or earning capacity.

Premises Liability

Property owners have a legal duty to maintain a safe environment for visitors. Slip and fall incidents, inadequate security, and other dangerous conditions can lead to serious injuries.

When premises liability is involved, we conduct a thorough investigation to determine negligence. This can include reviewing building codes, maintenance records, and incident reports. We aim to secure compensation that addresses immediate medical needs, ongoing treatment, and the broader impacts on your quality of life.

Animal Attack Cases

Dog bites can leave emotional scars and require extensive medical care. The Law Office of Mark A. Siesel has represented numerous clients in dog bite cases, pursuing compensation for medical treatment, pain and suffering, and the long-term effects of trauma. We understand that these cases require sensitivity, prompt action, and careful negotiation with insurance carriers.

Bus, Truck, and Motorcycle Accidents

Accidents involving larger vehicles often result in more severe injuries. From city buses to commercial trucks and motorcycles, these cases require a deep understanding of commercial liability and insurance coverage.

We evaluate each accident meticulously, gathering evidence from police reports, vehicle inspections, and witness statements. Our goal is to ensure victims are not left dealing with medical bills, lost income, and long-term rehabilitation costs on their own.
