About MMZ Law
Every family has a story. Every legacy deserves protection. At MMZ Law, we step into the storm with you - calm, clear, and unyielding. Where love and law meet, that is MMZ Law.
Mission and Vision
At MMZ Law, we walk beside families in their darkest hours - through loss, betrayal, and legal battles that feel impossible to face alone. With fierce protection and unwavering compassion, we ensure every voice is heard, every legacy honored, and every right defended. We know that probate, conservatorship, and estate disputes are not just legal processes - they are human struggles, layered with grief, conflict, and fear. That’s why we bring more than technical expertise, we bring calm strength and clarity that families need to move forward. Our vision is simple yet profound: no family should ever face these storms without protection, peace, and a trusted team at their side. This is where love and law meet. This is MMZ Law.

Our Core Values
Fierce Compassion
We may lead with heart, but we never back down. Love demands both empathy and strength.
Loyalty Beyond Loss
We don’t disappear once documents are signed. We walk with families through grief, conflict, and healing.
Peace Through Protection
In the storm of grief and division, we restore order, resolve disputes, and defend the wishes of those who can no longer speak.
Unshakable Integrity
We fight for what’s right - with honesty, transparency, and justice.
Commanding Authority
In a field built by men, we’ve earned our respect through brilliance, grit, and the quiet power of feminine strength.
Empowerment Through Guidance
We don’t just solve problems - we empower clients to make choices that honor their loved ones and protect their legacy.
The Heart of MMZ Law
Marivel Zialcita didn’t build MMZ Law for accolades - she built it because she lived the pain of being unprepared. When her father and uncle became gravely ill, there were no powers of attorney, no plan, and no one to guide her through the chaos. She felt what so many families feel: the crushing weight of grief colliding with legal uncertainty. Out of that storm, her purpose was born.
A first-generation Filipina, Marivel became a “quiet storm” herself - leading with compassion while carrying unshakable strength. That balance defines MMZ Law. Today, her all-female team fiercely protects families through probate, conservatorship, trusts, special needs planning, elder law, and estate disputes. More than attorneys, they are protectors, bringing peace, clarity, and dignity when families need it most. Families don’t just hire Marivel and her team - they trust them. And they stay, because they’ve found something rare: brilliant attorneys with human hearts.


Meet Our Attorneys

Marivel Zialcita
Founder / Attorney at Law
Marivel M. Zialcita has been a trusted attorney for more than 20 years, but her story is not just about years of practice - it’s about purpose. A first-generation Filipina, Marivel experienced firsthand the pain of loss without legal protection when her own family faced illness and uncertainty. Out of that storm, she built MMZ Law - a boutique, all-female firm devoted to protecting families, seniors, and those unable to protect themselves.
Known as a “quiet storm,” Marivel balances fierce advocacy with profound compassion. Her clients see her not only as a skilled attorney but as a steady presence in their most difficult moments. Beyond the courtroom, she is a respected voice in the legal community, frequently teaching on trust and estate matters for the National Business Institute, New York Life, and Mass Mutual. She also serves her community as a board member of the Estate Planning Council of Pomona Valley.
To her clients, colleagues, and community, Marivel is more than a lawyer - she is a protector of stories, legacies, and families. She is the heart and soul of MMZ Law, and she will defend you and all that you love with unshakable strength and unwavering care.
Soo Myland

Soo J. Myland is more than an attorney - she is a guardian of legacies and a steadfast ally to the families MMZ Law serves. With expertise spanning estate planning, succession, wealth preservation, probate, and special needs protection, Soo brings both technical mastery and a profound human touch to every case. She works alongside Marivel as a true partner, ensuring that every client’s life work, passions, and achievements are safeguarded for the generations that follow. Deeply involved in her community, Soo serves on the boards of the San Antonio Regional Hospital Foundation and the Inland Empire United Way, and her philanthropic heart extends to protecting animals and the defenseless. Her global perspective, combined with her relentless commitment to justice, makes her an anchor of both wisdom and compassion at MMZ Law.
