Tameka O’Brien
Your Advocate for Family Law and Intellectual Property
Tameka Grantham O’Brien, founder of Grantham O’Brien Family Law in Chelmsford, holds herself to one standard. “I think about who I’d send my sister or best friend to for legal help. I strive to be that lawyer.”
Tameka has spent 20 years in courtrooms, first as a prosecutor and now as a family law attorney handling divorce, custody, support, and cases involving the Department of Children and Families. She pursues settlement first for a practical reason: an agreement lets clients decide what happens to their children and their finances, while a trial hands those decisions to a judge who will know the family for a few hours. She prepares every case for trial, because the other side settles on reasonable terms only when they know she is ready to try it.
In recent years, much of her practice has involved representing people leaving controlling relationships, particularly ones marked by financial manipulation. These cases take more than legal skill. They take an understanding of how control operates and what it costs someone to leave. Tameka also connects clients with a realtor, mortgage broker, therapist, and financial advisor, often before they realize they will need one.
“I’m dealing with good people in bad times in their lives. Once they’re done, they see they’ve gotten through tough times and how much better life gets.”
Clients often tell her they want a lawyer who communicates. She keeps a small caseload and offers weekly calls, so clients know where their case stands, what happens next, and when.
Tameka was raised in the Big Bend area on Florida’s west coast and earned her bachelor’s degree at the University of South Florida in Tampa. She received her Juris Doctor from St. Thomas University in Miami in 2005. While often working three jobs, she was an Articles Editor for the St. Thomas Law Review, Vice President of Moot Court, and a board member of the school’s chapter of the Florida Association for Women Lawyers.
She moved to Tampa in 2006 and prosecuted felonies at the Hillsborough County State Attorney’s Office until relocating to Massachusetts in 2010. In 2011, she opened Grantham Law, later renamed Grantham O’Brien Family Law when she married Christopher O’Brien, who practices education law.

Chris O’Brien, Of Counsel
Education and Special Education Law
Chris O’Brien grew up attending public schools in Chelmsford, where he and Tameka now live with their two sons. He earned his law degree from New England Law and a bachelor’s degree in business from Assumption University and has been a member of the Massachusetts bar since 2013.
Chris came to education law as a parent. He has sat on the family’s side of the table in the IEP process and knows how hard it can be to get a school district to provide what a child needs. That experience is why he represents students with disabilities and their families.
He reviews IEPs and negotiates changes, attends IEP and Section 504 meetings, and represents students in disciplinary hearings, bullying cases, Title IX investigations, and other school matters. His goal in each is to secure the services and support the student is entitled to.
Courts and state agencies also rely on Chris to protect children’s educational interests. He serves as an Educational Guardian ad Litem in the Massachusetts Juvenile Court and as a special education surrogate parent, making educational decisions for students who have no parent available to make them. He also accepts court appointments through the Committee for Public Counsel Services.
