In 1984, Ms. Dron joined Monteleone & McCrory as a litigator. Specializing in public and private construction law, Ms. Dron also has litigated and tried a variety of general business cases, labor and wage dispute matters, bond and indemnity claims, safety litigation matters, has defended several “serious and willful” cases before the Workers Compensation Appeals Board, and has defended employers in state court where the cause of the injury was alleged to be outside the exclusive jurisdiction of the Workers Compensation Appeals Board.  Ms. Dron also defends employers against citations from the Division of Occupational Safety and Health (DOSH) also known as Cal/OSHA, taking one appeal all the way to the California Supreme Court.
Moreover, during the last 25 years, Ms. Dron has developed extensive experience in defending complicated construction defect cases – in the 1980s regarding architectural issues and soil subsidence and since 1996, for the ready mixed concrete industry. Ms. Dron was a key trial attorney in the first “sulfate attack” trial in California (Peters v. Brighton) in 1999. She also spent almost one year in trial (2004/2005) in Castron v. Fieldstone defending a concrete supplier against sulfate attack allegations – the trial team was successful in excluding a majority of plaintiffs’ junk science evidence in the first phase and obtained a complete defense verdict in the second phase.

Ms. Dron also defended a concrete admixture supplier against a multi-million-dollar claim regarding subterranean garage issues in San Francisco's sinking and tilting Millennium Tower.  That case was settled in late 2020.

Ms. Dron litigates and tries cases in both state and federal courts throughout California, as well as matters before commercial arbitrators. She has acted as a private arbitrator on cases referred to her from the superior and municipal courts. She has earned the reputation as an aggressive and dedicated attorney.

Ms. Dron has been asked numerous times to speak in seminars for the construction industry on construction law, mechanic’s liens/stop notices/bond claims, construction claims, and Dig Alert.  She has also published numerous articles on safety issues for the Southern California Contractors Association’s magazine including “Musings On Safety For 2021” (Jan/Feb 2021), “Fatigue In The Construction Industry” (Sept/Oct 2019), and “Lockout/Tagout - It Is Not Just About Electricity” (July/Aug 2018).


Ms. Dron is a member of several professional organizations, including the Orange County Bar Association, the Los Angeles County Bar Association, the Safety Committee of the Engineering Contractors’ Association, and the Legal Committee and the Safety Committee of the Southern California Contractors Association. She is admitted to practice before all state and most federal courts in California. She is also admitted to the Ninth Circuit Court of Appeals.

In her spare time, Ms. Dron likes to garden, camp and fish with friends, travel and participate in international adventures with Productive Learning.  Ms. Dron has been an active alumni volunteer for The College of Idaho for decades and received it’s Alumni Service Award in 2019 for her volunteer work.  Moreover, in December 2020, Ms. Dron founded The Dron & Brown High Impact Experience Endowment Fund to provide an annual grant each year in perpetuity for a student’s high impact educational experience.  

Ms. Dron received her undergraduate degree in 1975 from The College of Idaho. She received her law degree from Pepperdine University School of Law in 1978, while working for Stang Hydronics, Inc. and attending night school. She was promoted to the position of Corporate Counsel and, during her tenure, developed a background in construction dewatering and heavy manufacturing.
