Daniel Lewis


Founder & Managing Attorney

Daniel Lewis is a zealous and compassionate advocate of individuals injured and impacted by mass torts, product liability, and other large-scale litigation matter. During his time at Hilliard Martinez Gonzales, his small team of attorneys worked diligently for over 60,000 Zantac clients, 20,000 opioids clients, and 2,000 Singulair clients. Prior to HMG, he spent several years as a solo practitioner who primarily represented his clients in multi-million-dollar corporate and domestic disputes. Whoever the plaintiff may be, Daniel’s vision for success has always been maintaining a firm understanding of the underlying case facts, aggressive yet fair negotiation of claim resolution, and robust empathy for the human component of litigation.

During law school, Daniel worked as a legal extern for Tennessee’s 23rd Judicial District Attorney’s office in West Tennessee on the Holly Bobo kidnapping, rape, and murder trial. The six-defendant case was attended by a search and rescue party numbering 10,000, and garnered national news coverage for years. He used straightforward communication with sensitivity to assist in guiding the young girl’s family throughout the DA’s prosecution of the men.

Daniel has played an integral role in mass tort actions across the country for plaintiffs. These cases have included the following: 1) Waste Serv. of Decatur, LLC v. Decatur County, Tenn, a toxic tort by a rural West Tennessee county against a landfill management company and industrial waste producers concerning groundwater contamination resulting from aluminum dross & slag disposal and EPA violations involving complex lab analyses and regulatory disclosures; and 2) Phillip v. C.R. Bard Inc. et al, multi-district litigation by pulmonary embolism patients against medical device company C.R. Bard concerning inferior vena cava (IVC) filter failures. Daniel feels that his educational background in the fields of biology, chemistry, and engineering gives him special insight into arguments that utilize extant scientific researh, complex lab analyses and clinical data, and regulatory schema to objectively bolster plaintiffs’ claims.

Daniel received his law degree from Vanderbilt University Law School, where he earned the school’s prestigious Law & Business Certificate and produced research that was incorporated into the respective publications of Professors Michael Vandenbergh and Margaret Blair. Endeavoring to improve his fellow students’ law school experience, he was active in student government and organizations—he served on the Hyatt Board fund to spearhead two high-profile symposia each year addressing the following current and complex legal issues:

Adoptive Couple v. Baby Girl, 570 U.S. 637 (2013), discussing the bounds of the Indian Child Welfare Act as applied to Native American children with non-custodian Native American parents;
Burwell v. Hobby Lobby Stores, Inc., 573 U.S. 682 (2014)., exploring the contours of the Religious Freedom Restoration Act as applied to closely held for-profit corporations.

He was Vice President of the Federalist Society, collaborating with the American Constitution Society to promote a bipartisan forum for discussing legal and public policy issues. Daniel was voted by his class as Mr. Vanderbilt Law School for the 2013—2014 academic year, performing “Trouble” from Meredith Wilsson’s Broadway smash The Music Man.

A proud Eagle Scout and Religious Emblem holder, Daniel serves on the board of the Middle Tennessee Council of Boy Scouts of America and advises the West End United Methodist Church’s Boy Scout troop. He is an avid mountaineer and is in the process of climbing the Seven Summits by the age of 40, a goal which traces back over thirty years. Currently, he is completing a PhD in Industrial and Systems Engineering from the University of Tennessee Space Institute, a PhD in Theology and Apologetics from Liberty University, and an MA in American and Military History from Austin Peay State University. Daniel’s free time is spent with his best friend, his lab-beagle mix rescue dog named Desi who is always by his side.
