Our Take
Why Exhibit
The largest oncology nursing conference in the US with 200+ exhibitors. Oncology nurses influence formulary decisions, infusion protocols, chemotherapy safety products, and patient monitoring equipment. Presentation Theaters give deeper engagement than booth-only presence.
Why Skip
Nursing audience requires different sales approach than physician conferences. If your device requires oncologist prescribing or hospital C-suite approval, ASCO is the physician-focused alternative. ONS is influential but downstream in the decision chain for capital equipment.
Insider Tips
Same venue (Henry B. Gonzalez Convention Center, San Antonio) as ASMBS 2026 but different dates (ONS in May, ASMBS also in May -- check for overlap). Presentation Theaters available. Pricing not publicly posted -- contact via onssponsorships.org.
