Hawaii-Western Management Group, Inc.

As one of the state’s largest health insurance management service companies, we utilize our exceptional infrastructure, technology, expertise, and accredited PPO provider network to exceed our clients’ expectations. We administer both fully insured and self-funded health plans for a wide range of organizations including Hawaii Medical Assurance Association (HMAA), Charter Communications (formerly Oceanic Time Warner Cable), Hawaii Electricians Local Union 1186, and labor unions.

HWMG was established by our founder Arnold Baptiste, Sr. decades ago with a vision to offer total employee benefit plan solutions to local businesses in Hawaii, regardless of their size. We honor that vision by supporting all of our customers through the dedication and commitment of more than 130 team members. We are proud to be 100% employee-owned through our Employee Stock Ownership Plan.

HWMG has also developed a presence in the Pacific Northwest by partnering with The Confederated Tribes of Grand Ronde, with whom we jointly own Shasta Administrative Services, a third-party administrator based on Oregon.
