Consistency Across Matters and Counsel

Lighthouse experts document their processes to ensure there’s no overlap or wasted time on previously reviewed documents and keep track of data and searches for reuse in future matters. We’ve successfully served as a centralized search desk for joint defense groups for multi-district litigations. And, we build institutional knowledge with each engagement, making us more efficient with every matter.
