We advise our clients about directors' and officers' liability, dissolution, franchising, reorganization, trade association membership and activity, joint ventures, mergers, acquisitions, divestitures, business successions and shareholders' rights.

Real Estate

Social Security Disability

If you are unable to work due to a disability, we can help you apply for benefits, appeal the rejections and navigate the bureaucratic processes that almost all applicants have to contend with in order to get SSI or SSD benefits. We will not receive legal fees unless and until you are awarded benefits.


We represent clients in different types of adoption matters, helping them add to their family or formalize existing family relationships. We can advise you on what your adoption will entail, and we can help you handle the extensive paperwork that must be completed in a timely manner.
