About Us


About Us

If someone asked you what is most important to you, you would probably say your family and your home.

Carvajal & Nielsen was created to protect what’s most important to you. Carvajal & Nielsen practices family law, including divorce and cases involving custody or guardianship of children, and housing law, including cases of discrimination, and landlord-tenant disputes. We also represent clients in other legal matters, including personal injury and employment discrimination.

When your family or your home is involved, you need a law firm you can trust to protect you and your legal rights, and to advocate on your behalf. When Sergio Carvajal and Arose Nielsen decided to form a new law firm in 2007, they wanted to form a firm that would create client trust by:

  • Taking a practical and sensible approach to practicing law. Dragging on cases often helps the attorney more than the client. We put our clients first.
  • Paying attention to clients’ costs. By controlling costs, our clients end up with more when a case is settled.
  • Providing clients what they need. When we discuss your case, we will develop a legal strategy based on your needs. Sergio Carvajal speaks Spanish and can provide you with bilingual representation as needed.

Carvajal & Nielsen seek to serve the needs of the community through civil litigation in landlord-tenant disputes and housing discrimination matters, and in the practice of family law. We also provide private or court-appointed representation in Massachusetts District Court, mental health litigation, child welfare issues (DCF) and contested guardianship matters.
