Representative Matters

Coverage Counsel to large regional health care provider

GTTC lawyers Frank Cordell, Chelsey Mam, and Guin Bogusz represent a regional health care provider in a claim against its insurers under an employment practices liability policy written on a claims-made-and-reported basis.  The insurers denied coverage on grounds that the policyholder had failed to timely notify the insurers of the claim.  The policyholder notified the insurers of the claim during the policy period, but after the 60-day deadline established by a policy condition.  The GTTC team successfully argued that, under these circumstances, Washington’s “prejudice rule” applies, meaning that the insurers are not relieved of their coverage obligation unless they can prove actual and substantial prejudice as a result of the delay in notice.

Coverage Counsel to Snohomish County after Oso landslide tragedy

On March 22, 2014 a massive landslide killed 43 people in the Steelhead Haven neighborhood near the community of Oso in Snohomish County, Washington. In the aftermath, victims and their families filed dozens of wrongful death claims against three defendants, including Snohomish County. These claims have been consolidated in King County into the State’s largest-ever wrongful death action. Frank Cordell was selected to represent the County as coverage counsel, and, along with Chelsey Mam and Greg Pendleton, currently is prosecuting litigation against the insurers in federal court in Seattle.

 

Long-tail coverage counsel to Weyerhaeuser Company

For nearly 30 years, GTTC’s lawyers have served as coverage counsel to iconic Northwest business Weyerhaeuser Company. Frank Cordell and Susannah Carr, with the help of Chelsey Mam, represented the company in litigation against the London Market, AIG, and other insurers over coverage for liability arising out of the Kalamazoo River Superfund Site, one of the largest and most costly Superfund sites in history.

 

Negligence case against apartment complex in hash oil explosion

A tenant manufacturing hash oil in his Bellevue apartment caused a massive explosion that destroyed ten apartments and their contents and injured residents. With the help of Michael Rosenberger and Chelsey Mam, a tenant who lived next-door to the hash operation sued Hampton Greens Apartments and its property manager, Riverstone Residential West, for negligence. Despite having received a report of the drug operation, the complex and the property manager had failed to take action to commence eviction. In a 2015 bench trial, the King County Superior Court awarded GTTC’s client the full value of his destroyed property and general damages within the specific range asked for in closing argument.

Personal

Prior to law school, I studied abroad at Kwame Nkrumah University of Science and Technology in Ghana. My travels have also taken me to Europe, Costa Rica, and the Canary Islands. As a new attorney, my travel has been less extensive in recent years.  Instead, much of my free time is spent with family or taking road trips in the beautiful Northwest. I also enjoy playing softball on a co-ed team, dance fitness, camping, and gardening.
