"This was my first ONS as an exhibitor attendee and it was a really well-executed conference. The ribbons for our badges were a nice touch that allowed for organic conversation starters."

— 2026 Exhibitor

"Our team had a very productive meeting, with valuable opportunities to connect with current customers, reconnect with longtime colleagues, and spend meaningful face time with prospective HCPs/customers. We’re already looking forward to next year’s event."

 — 2026 Exhibitor

"This was my first ONS congress and I was quite impressed with the extent the organization goes to ensure attendees feel appreciated. Little things like the ribbons at check-in, the badge holders, etc all show detailed understanding of what nurses do and how to have good conversations with patients by using these small ice breaker items."

 — 2026 Exhibitor

"We truly valued the opportunity to exhibit at ONS Congress and were grateful for the chance to engage with such a thoughtful, forward-looking nursing audience. The level of conversation and collaboration made the experience especially meaningful for our team. We appreciate the effort that went into creating such a well-executed event and look forward to continuing the relationships and insights that began there."

 — 2026 Exhibitor

"Exhibiting at ONS was highly valuable for our foundation. The conference gave us an important opportunity to connect directly with oncology nurses who support these patients every day.  We spoke with approximately 250 nurses, many of whom were not previously aware of our organization."

 — 2026 Exhibitor

"The ONS network and conference events provided valuable opportunities to strengthen relationships with key oncology nursing professionals and expand our visibility within the oncology community. It gave us meaningful exposure and created opportunities for direct engagement with nurses who play an essential role in patient education, treatment coordination, and overall patient support."
