David Ericksen is a trusted resource and advocate to the professional service community (design, construction, environmental, real estate, and insurance) and passionately committed to collaboration in their long-term strategic success.

Since 1997, David Ericksen has led the Firm’s Construction/Environmental Litigation and Transactional Practice, as well as focusing on liability and insurance issues through insurers.  He has repeatedly and successfully represented design professionals in jury trial, bench trial, single arbitrator arbitration, and panel arbitration as well as mediation and other forms of alternative dispute resolution in state and federal courts.

He has written numerous articles addressing issues important to the design and construction communities which have been published by professional organizations and industry related periodicals.
