Renee Diaz is Senior Counsel in Freeman, Mathis & Gary’s downtown Los Angeles office.  Design professionals, owners, and contractors rely on Ms. Diaz’s counsel to guide them through conflicts involving contract, lien claims, delay claims, unforeseen site conditions, payment remedies, licensure, and claims of defective design or construction. Ms. Diaz’s practice also includes defending attorneys in professional liability matters, counseling clients in real estate and commercial disputes, advising businesses on risk exposure and risk management, and negotiating cost effective resolutions. Among her notable engagements was demonstrating that a multi-million dollar subrogation mold claim against the project architect was negated by the doctrine of superior equities as the general contractor failed to properly install antimicrobial flooring material, spurring a settlement for a fraction of the claimed value, and achieving the early dismissal of suit against a law firm and attorneys negating a freelance paralegal’s claim that the law firm was obligated to pay for the paralegal’s fees for services despite a written contract obligating the fees be paid by the firm’s client, a dismissal that was upheld on appeal.

Prior to joining the firm, Ms. Diaz represented corporate clients, including Fortune 100 and 500 companies, in complex products liability and catastrophic injury actions involving medical devises, pharmaceutical drugs, and off-road vehicles.
