I represent owners, general contractors, subcontractors, and public entities in all aspects of construction litigation.

I enjoy partnering with our clients to assess early solutions and help them negotiate out of, or in the context of, mediation.

What do you see on the horizon?

I follow the disruptive impact that new technologies, such as 3D printers, drones, and Artificial Intelligence are likely to have in the construction industry.

I follow the investing and banking trends in Latin American and can see changes in Mexican Law, specifically in the renewable energy industry, that may have an impact on foreign investors and are likely to result in international arbitration.

I follow the impact that wildfire activity can have on California residents and businesses at a legislative, regulatory, and insurance level.
