The file sometimes leaves a certification out, and a newer one won't be in it yet. Self-reported business types are what the firm says about itself on SAM.gov; they aren't SBA certifications.
Check or correct this record at the source: open its SAM.gov entry, or search UEI QJLHFFWJ6NJ6 () in SAM.gov's entity search (free sign-in) and in SBA's Small Business Search (formerly DSBS), which shows SBA certifications. The business can update its details in its SAM.gov registration and its certifications at certifications.sba.gov.

Open contracts in Linda C. Zeigenfuss's NAICS codes
48 open federal opportunities on SAM.gov use one of Linda C. Zeigenfuss's NAICS codes and may be open to it: no set-aside, or, in the codes it is registered small under, a small business set-aside or one for a status it reports about itself on SAM.gov (women-owned (WOSB)). Here are a few, those in its primary code first (none of these are in Washington right now), then the soonest due.
Confirm eligibility first. Linda C. Zeigenfuss's women-owned (WOSB) status is self-reported on SAM.gov, and this page can't confirm an SBA certification for it, so set-asides for it may be relevant but may not be open to it: WOSB and EDWOSB set-asides need SBA WOSB program certification. SBA's Small Business Search shows a firm's current certifications.
