Mark S. Simms

President & Attorney at Law

I am an attorney and President of Simms Law, P.C. My focus practice areas include representation for investors and financial advisors as well as business law and civil litigation. I received my Juris Doctorate from the University of Miami School of Law with cum laude honors. Immediately after law school, I jumped into the federal court system and began assisting with the infamous Bernie Madoff Ponzi scheme. I transitioned into working with brokerage firms but realized I valued assisting the clients that were being taken advantage of by these firms and decided to represent them instead.

Why You Should Work with Me

Let Me Take Charge

Experience On Both Sides of the Aisle

When I started practicing law, I represented the brokerage firms against the customers. I opened my own practice and began to advocate for the customers who were being ripped off by big businesses. With my experience, I can anticipate what tactics the opposing side may use and can diligently prepare for it.

Personal Engagement

Being a solo practitioner, I am able to give my clients my undivided attention. I will listen to your troubles and enjoy getting to know whoever walks through my doors. I aggressively fight for my clients and will take charge when combatting the opposing counsel to help you pursue the best possible outcome for your case.
