Attorneys + Engineers + Contractors



Be Represented by an Attorney/Engineer/Contractor

Dr. Vida Tarassoly is an attorney, a registered civil/structural engineer, and a licensed contractor. She holds a Ph.D. in structural engineering from the University of Southern California. With over 20 years of practical experience in engineering and construction of complex projects for the public and private sectors, she is uniquely qualified to assist her clients in the dual capacities of an attorney as well as a technical expert. When other attorneys have to rely on the expertise of hired technical experts, Dr. Tarassoly evaluates the technical aspects of your case more cost-effectively and expeditiously, often at the initial meeting.

         "I represent my clients as an attorney and a technical expert. Other construction attorneys would have to                 rely on hired technical experts to build your case, and most often issues could get lost in translation. I                           provide you an attorney outside who has an engineer/contractor inside. I  can assess the technicality of your             claim  and your legal rights to compensation for your damages."

We specialize in Construction Law. Because of Dr. Tarassoly's high technical expertise as a structural/civil engineer and a contractor, and her full understanding of the entire construction process, she is uniquely qualified to provide her clients with sound legal advice as well as technical evaluation of their claims. In cases involving construction defects,  our clients particularly benefit from Dr. Tarassoly's ability to serve in the dual capacities of attorney and expert. Usually, expert witnesses are assigned in later phases of litigation at high costs to clients. Prior to the technical review of your case by an expert, a construction attorney could not definitively decide the strength of your case. The success of your construction dispute is as much, if not more, dependant on the development of the technicality of your claim as it is based on your legal stance. Dr. Tarassoly's insight into the technical clients benefits from her unique ability to provide the requisite technical expert opinion in their cases saving them time and money. We represent developers, general and subcontractors, material suppliers, architects and engineers providing legal support including review and draft of contracts, Permitting, California Contractor's License Board interface, stop notice services, mechanics' lien filings and removals, latent construction defects, delay claims, change orders, issues relating to a violation of SB800 right to Repair Act, litigation, arbitration, and mediation. 


"Being an expert in the engineering and construction fields, I have the unique ability to effectively eluate the technical strength of your claim, as well as your legal stance in your construction dispute. My technical insight into your dispute puts me at an advantage over other construction attorneys. "

"Shortly after moving into my newly constructed home, it was determined that the lot contained expansive soil capable of damaging the home's structural integrity.  Upon learning of this, I began searching for a qualified construction defect legal services provider capable of effectively representing me in legal mediation with the builder.  I was delighted to discover the services of Dr. Vida Tarassoly.  Not only is she an experienced construction defect attorney, but she also holds a Ph.D. in Structural Engineering from a prestigious California university.  Following the engagement of her firm's services, she represented me in the first mediation hearing where she engaged the builder's legal representation about the expansive soil on my lot and possible remediation remedies.  She arranged for professional geotechnical soils testing on my lot and from the test results, her firm developed well-considered engineering plans for remediation of my property.  Continuing her representation in the mediation process, she was effective in using this evidence to help me reach a fair and equitable settlement with the builder.  I can highly recommend her firm's professional services for matters concerning construction defects."
