Willamette Dental Group Market Analysis: Market Share and Coverage by State
Willamette Dental Group is a regional dental insurer focused on the Pacific Northwest. It plays a modest role in the national market while concentrating membership and premium in three adjacent states.
Payer Overview
Willamette Dental Group operates as a regional dental payer with a concentrated presence in the Pacific Northwest, ranking as the #182 US A&H payer by premium. Its reported US premium is $153.03M, representing a 0.01% US market share and a footprint across 3 states. The organization serves an estimated 22.8K members and operates through 3 affiliated subsidiaries, which supports its market activities across Idaho, Oregon, and Washington.
Willamette Dental Group does not hold a #1 position in any single state. The payer's US premium reflects its focused strategy within a limited number of states rather than a broad national footprint. This concentrated profile shapes contracting leverage and network strategy, especially for multi-state provider groups operating in the Pacific Northwest.

| National Total | — | $153.03M | 22.8K |
Willamette Dental Group shows heavy concentration in the Pacific Northwest, with $153.03M of premium written across three states and an estimated 22.8K members. The bulk of premium is in Oregon and Washington (each roughly $69M), indicating regional scale that can influence reimbursement levels and network design locally. For national payers and provider groups, this concentration means negotiating leverage and utilization patterns will reflect Pacific Northwest market dynamics rather than national averages.
State-by-State Market Position
Willamette Dental Group's strongest presence is in the West region, specifically the Pacific Northwest where Oregon and Washington together account for the majority of premium. Idaho contributes a smaller but meaningful share. There is no material footprint reported in the Northeast, Midwest, Southeast, or Southwest regions, so multi-region provider groups should view this payer as a regionally concentrated counterparty.
Because premium and membership are concentrated in contiguous states (OR, WA, ID), multi-state provider groups operating across these borders can pursue coordinated contracting strategies to capture regional scale. The payer's concentrated premium profile means provider negotiations will likely be most impactful when targeted at the Oregon and Washington markets where premium levels are roughly $69M per state.

Nationally, the largest age bands are 35–44 (3,516 members), 6–18 (3,475 members), and 45–54 (3,116 members). The distribution is relatively balanced, with substantial representation in both pediatric and adult populations. The senior bands (65–74 and 75+) are smaller but still notable, indicating a moderate presence of older adults.
State-level analysis shows Washington has the largest member counts across all age bands, followed by Oregon and Idaho. No state skews dramatically older or younger, but Idaho has slightly fewer seniors and children compared to Oregon and Washington. Overall, the member profile is diverse, requiring providers to address a wide range of dental needs.
Estimated Members by State
WILLAMETTE DENTAL GRP's estimated member distribution is concentrated in three states: Washington (11,669 members), Oregon (7,980 members), and Idaho (3,186 members). Washington leads in total members, reflecting both a higher premium volume and a substantial market share. Oregon follows closely, while Idaho, despite a lower premium and market share, still maintains a significant member base.
This geographic concentration aligns with the payer's market share and premium written in each state. Washington's dominance in member count is consistent with its premium volume, while Oregon's strong presence is reflected in both market share and member numbers. Idaho, though smaller, remains an important market for the payer. For providers, this means that contracting strategies should prioritize Washington and Oregon, with Idaho as a secondary focus. The regional concentration suggests that multi-state provider groups in the Pacific Northwest are best positioned to engage with WILLAMETTE DENTAL GRP's member base.
