We take every case very seriously.  If you believe you may qualify you for Social Security Disability/Supplemental Security Income (even if you have applied and been denied), contact us today to discuss for a free, no pressure, consultation.  If we take your case, you pay nothing out of pocket.  There is only an attorney fee (taken from past due benefits) if we successfully get you benefits.


Attorney Mark Dean helped me through my appeal process and hearing. I highly recommend him to anyone who needs help. He is very knowledgeable in the social security process.

I highly recommend the Law Offices of Mark Dean to anyone seeking help with their social security disability case. I refer anyone with social security disability or social security income problems to Mark because I know that he is highly experienced and will get great results for my referrals. If you are looking for legal help look no further.
