Early Life: Roots in Resilience

William's journey began in Puerto Rico, a U.S. territory whose residents have been U.S. citizens since the passage of the Jones-Shafroth Act in 1917. In the mid-20th century, a series of economic development initiatives known as Operation Bootstrap aimed to industrialize Puerto Rico's economy. While these efforts brought infrastructure and manufacturing to the island, they also disrupted traditional industries and led to rising unemployment. By the 1960s, Operation Bootstrap was increasingly hampered by a growing unemployment problem. As living standards and wages in Puerto Rico rose, manpower-intensive industries faced competition outside the United States. It also faced criticism from civil rights groups and the Catholic Church, who perceived the government as promoting birth control and engaging in non-consensual surgical sterilization. Social Darwinism influenced American industrialists through eugenicist policies, concerns with overpopulation, and a perceived lack of self-control on the part of the working-class Puerto Ricans.

As a result, many Puerto Rican families—including William's—moved to the mainland United States in search of opportunity. Though legally domestic, this internal migration often felt like crossing into a different world.

William and his mother arrived in the continental U.S. in 1960 without a financial safety net. They initially lived with relatives while William's mother worked in a garment factory to make ends meet. Eventually, they were able to transition to a modest apartment in a low-income neighborhood. As a young Spanish-speaking child starting school in an English-speaking environment, William faced ridicule from classmates, indifference from teachers, and a society that was unprepared to embrace linguistic and cultural diversity.

But William did not retreat—he adapted. He learned English quickly and took on adult responsibilities while still a child, navigating a system often indifferent—or even hostile—to people like him. These early experiences instilled in him a powerful sense of justice and a deep-seated commitment to helping others who feel voiceless or ignored.

Education Through Adversity

Despite the odds, William's mother was determined he would get an education. After graduating high school, he began working full-time and shortly thereafter started a family. He pursued higher education at night, often with the support of employer tuition reimbursement programs that required job-specific coursework. Over the course of several years, William earned a Bachelor of Science in Computer Science & Mathematics from Montclair State University and a Master of Science in Operations Research from the New Jersey Institute of Technology.

These achievements were not easy. Balancing full-time work, family responsibilities, and school, William displayed exceptional perseverance and drive. His educational journey is a testament to his core belief: that determination and vision can chart a path forward no matter the circumstances.

Corporate Experience and Technical Expertise

Before practicing law, William built a successful career in the corporate world. For more than 25 years, he worked as an IT consultant, systems analyst, and project manager. His experience spans major corporations and international projects, where he led complex system implementations, managed multi-disciplinary teams, and developed innovative business strategies.

His technical background in ERP systems, SAP configuration, and digital data management has proven invaluable in his legal practice—particularly in internet law, cybersecurity, and digital forensics cases. William brings a rare analytical depth to the courtroom, enabling him to dissect complex technical evidence, challenge digital claims, and protect client data and rights with the fluency few lawyers possess.

The Call to Law

Despite a thriving career in technology, William never lost sight of his childhood dream: becoming a lawyer. After fulfilling his family obligations and seeing his daughter graduate from college, he finally pursued what had been dormant for decades. He earned his Juris Doctor from Thomas M. Cooley Law School, where he distinguished himself in courses like eDiscovery, Family Law, and Digital Evidence.

Now, as a practicing attorney, he has found his true calling. William draws from every facet of his life—his early struggles, professional discipline, cultural fluency, and personal empathy—to serve his clients with care and tenacity.
