SSDI & SSI Attorney

St. Louis Metro Area (Missouri and Illinois) SSDI & SSI Attorney

The Law Offices of Mark Dean provides a local, experienced attorney to handle your Social Security Disability (or Supplemental Security Income) case from the initial application (if needed) or to handle your appeal after an initial denial.

We know the process and how daunting and complex it can be for someone who is not familiar with it.  The Social Security statistics show that having an experienced attorney handle your case greatly increases your chances to be awarded benefits.  The reasonable contingency fee easily pays for itself.  Moreover, all attorney fees come out of back benefits.

We are not a national Social Security firm that simply looks as your case as a number among thousands.  We will treat your case with the individual attention it deserves and will not take a case if we do not feel the chances for success are favorable.  Mark Dean appears before the local Administrative Law Judges frequently.

We take the time to answer your questions and help you through the process, ensuring that the Social Security Administration has all of the records to properly assess your claim.  We will discuss with you how to best work with doctors and we will work with your doctors ourselves so that all your medical and/or mental ailments and limitations are documented to fully assist your case.

If you do not have consistent medical or mental care, we will assist you in helping to get the care you need.

All SSDI & SSI cases are handled on a reasonable contingency basis.  You pay nothing up front.  To discuss your disability claim, call me for free at 314-623-9126 or 618-208-0900.  I am happy to meet with you personally at any one of my numerous offices in the St. Louis metro area or come to your home if you lack transportation or have difficulty traveling due to your disabilities.
