Kaiser Permanente, whose acquisition of Group Health Cooperative became permanent on Feb. 1, is marking the merger by “turning the town blue” across Washington.

Kaiser Permanente Tacoma Medical Center, on 209 Martin Luther King Jr. Way in Tacoma, will join the festivities on Monday with the unveiling of its official Kaiser Permanente signage. The sign will be unveiled at 6:30 a.m., coinciding with simultaneous activities in Seattle, Spokane, Bellevue and Everett.

Metro Parks in Tacoma will also be lit blue the prior evening to commemorate the event.

Other former Group Health facilities across the South Sound have already switched signage to reflect the acquisition. Kaiser Permanente now serves more than 11.3 million members in eight states and the District of Columbia.

“We are proud to extend our integrated model, delivering the future of health and health care to the residents of Washington State,” said Bernard J. Tyson, chairman and CEO of Kaiser Permanente, on Feb. 1. “Since our inception 71 years ago, we have continued to deliver high-quality, affordable and accessible coverage and care to more people and communities in ways that align with our mission. Kaiser Permanente and Group Health have had a working relationship stretching back nearly 20 years, and this collaboration has resulted in high-quality care outcomes and medical excellence. We are honored to build upon the legacy of health care leadership in Washington State.”
