A Lifetime Commitment to Houston Families
Mary Armstrong has spent over 15 years helping Houston families navigate some of life's most difficult transitions. After graduating with honors from the University of Texas School of Law, she dedicated her career exclusively to family law — believing that every person deserves a fierce and compassionate advocate during their most vulnerable moments.
Born and raised in Houston, Mary understands the unique challenges facing Texas families. Her practice emphasizes mediation and collaborative solutions when possible, but she is an aggressive litigator when her clients need it most. She has been recognized by Texas Super Lawyers five years running and holds a Board Certification in Family Law from the Texas Board of Legal Specialization — a distinction held by fewer than 1% of Texas attorneys.
When not in the courtroom, Mary volunteers with Houston's domestic violence legal aid clinic and mentors young women entering the legal profession. She believes deeply that access to quality legal representation should not be limited by financial resources, and she contributes hundreds of pro bono hours each year to ensure Houston's most vulnerable residents have a voice.
Every family's story is unique. My job is to listen, to understand what matters most to you, and to fight for the outcome that protects your future.
— Mary Armstrong, Board-Certified Family Law SpecialistMary's Approach to Family Law
Family law cases are not just legal matters — they are deeply human experiences. The decisions made during a divorce or custody case can shape a family for decades. Mary takes that responsibility seriously. Before drafting a single motion, she invests real time in understanding what her clients need most: financial security, time with their children, protection from an unsafe situation, or simply the ability to start a new chapter with dignity.
Mary is known for her methodical preparation, her honesty with clients about realistic outcomes, and her composure in high-conflict situations. She is not the attorney who overpromises to win your business — she is the attorney who delivers results and explains exactly what to expect along the way.
