William began his legal career on the plaintiff's side, representing Florida homeowners and businesses whose lives had been upended by hurricanes, tropical storms, and severe weather events. He saw firsthand what families go through when an insurance company drags its feet, lowballs a claim, or denies coverage altogether — and he learned how to recover what his clients were owed.

He then crossed over to the other side of the courtroom, joining an insurance defense practice where he represented major carriers in litigation across a broad spectrum of plaintiff claims. That experience was deliberate. William wanted to understand exactly how insurance companies evaluate exposure, build defenses, decide what to pay, and choose what to fight — because effective plaintiff's advocacy starts with knowing the defense playbook by heart.

William then moved to a Big Four accounting firm, where he went on to represent Fortune 500 clients in complex state and local tax controversies. He has defended clients in high-stakes disputes with taxing authorities across the country, building a practice grounded in deep technical knowledge and seasoned advocacy.

This dual fluency in tax and insurance defense gives Pereira & Associates a perspective uncommon among solo and small firms — the ability to evaluate a case through both regulatory and litigation lenses, and to anticipate the moves the other side is most likely to make.

Today, William brings all of that experience back to where his career began — representing everyday people and small businesses. When he sits across from an insurance adjuster or a defense attorney, he already knows their next several moves. When he walks into a hurricane or storm damage case, he knows how to document what a properly-valued claim looks like. And when a tax matter threatens a client's livelihood, he knows how to take it head-on.

At Pereira & Associates, clients are family. William founded the firm to be a place where injured people, grieving families, distressed property owners, and small business owners would be truly heard — not handed off, not rushed, and not treated as a file number. Whether the matter is a serious car accident, a denied property damage claim, a wrongful death, an IRS notice, or the formation of a new business, William personally engages with each case and works to ensure every client leaves feeling seen, supported, and respected.

His approach is direct: relentless preparation, transparent communication, and a willingness to take on corporate goliaths on behalf of the everyday client.
