Meghann L. St. Thomas

Meghann grew up in Maryland and attended Towson University, graduating cum laude with a B.S. in English Literature and Creative Writing. Realizing she would likely never become a published author, she relocated to San Diego to attend California Western School of Law. While in law school, Meghann’s passion for activism was born and she spent time volunteering at the San Diego AIDS Legal Clinic.

Meghann has spent her entire career advocating on behalf of those devastated by the negligence of others. Meghann moved to Arizona after law school and for the first eight years of her career, Meghann worked at a prominent Phoenix Plaintiff’s firm primarily focusing on civil rights, wrongful death, personal injury and sexual abuse cases against government, education and religious entities. Meghann then transitioned her passion for justice to representing victims of medical malpractice, catastrophic personal injury, traumatic brain injury, trucking collision, negligent security and premises liability. Whether representing plaintiffs against government or corporate entities, the fight is the same; advocating passionately for clients who need it the most.

Meghann and Jeffrey co-counseled on medical malpractice and complex catastrophic personal injury cases for six years before Meghann joined Gill Law firm in 2019. Together they have successfully litigated cases with settlements totaling over $17,000,000.00. They have achieved remarkable results by taking tough cases that other attorneys have rejected due to their complexity and risk and finding creative ways to obtain outstanding recoveries for their clients. Meghann believes every case is taken for trial and every client deserves her complete attention and passion.

Meghann makes the most of an attorney’s rare spare time, fighting the good fight as an activist and an artist in Phoenix.
