Many years ago, I was questioned about my motivation to become an attorney, and I simply said, “To help those who cannot help themselves.”

I firmly believe that by retaining me as your attorney, you will secure a better result than you could do on your own, and you can rest assure that I will not permit the insurance company or their hired attorney to trample on your rights.

I can promise you that I will zealously represent you in court, I will diligently handle all aspects of your claim, and I will deal with you in a respectful and courteous manner.

About New York State Workers CompNew York State Workers’ Compensation Law provides cash benefits and/or medical care for workers who are injured or become ill as a result of their job. The injury can be caused by a single trauma or it can arise out of the performance of repetitive activities at work.

A monetary and/or medical claim is paid if the employer or the workers’ compensation insurance carrier agrees that the injury or illness is job-related. However, when the employer or insurance carrier disputes the claim, then no benefits are typically paid until the matter is tried before a workers’ compensation law judge who decides whether or not the claim is compensable.

If the claim is accepted voluntarily or if it is established after a hearing, cash benefits are paid if the worker is either totally or partially disabled, and they are out of work more than seven days. The amount that the worker receives in weekly cash benefits is based upon their average weekly wage for the previous year and the level of their current disability. These weekly cash benefits are tax-free.

Workers’ compensation law also provides for necessary medical care no matter how short or how long the worker is out of work if the treatment is causally-related to the claim. Many types of treatment including chiropractic care are pre-authorized for a certain number of visits.

Further, in almost all situations, an injured worker may be entitled to an additional cash award depending on the body part affected and the nature of the permanent disability.

At Cellino and Barnes, we strive to zealously represent the injured Buffalo or Rochester worker in all aspects of their workers’ compensation claim from handling routine issues like prescription medicine authorization to complex litigation involving the testimony of multiple witnesses and doctors.

If you have any questions concerning an on-the-job illness or injury, please feel free to contact David C. Zimmerman who specializes in workers’ compensation law and has represented injured Buffalo and Rochester workers for over twenty years.

Remember, consultations are free.

Client Thanks

I would like to thank your firm for representing our family on behalf of my late husband. This whole process was, at times, difficult for us and sometimes painful. But, we were always in good hands as Brian and Maria are two of the hardest working and sincerest people I have ever had the pleasure of meeting. They did a tremendous job.
