September Professional Interchange @ Altezza Rooftop 2026

GRNBA Professional Interchange: Not transactional and fostering strong relationships!

Join us this September for our next Professional Interchange at Altezza Rooftop, one of River North’s elevated gathering spaces and the newly reimagined former 101 Rooftop.

Professional Interchanges are designed to bring together business professionals, entrepreneurs, and community leaders in an environment centered around authentic connection and meaningful conversation. More than a typical business event, these gatherings create opportunities to exchange ideas, strengthen relationships, and engage with others in a setting that feels intentional, welcoming, and memorable.

Set above the city, Altezza Rooftop provides the perfect backdrop for an evening of conversation, fresh perspectives, and community. Whether you are reconnecting with familiar faces, meeting new people, or attending your first GRNBA event, this is an opportunity to experience what makes our community unique.

Open to both members and guests, Professional Interchanges continue to be one of GRNBA’s signature ways to bring people together and foster relationships that extend beyond the event itself.

Attendance is limited and registration is encouraged.

This event is made for GRNBA members, and open to the public for a fee. 

Important Information: All registrations are nonrefundable and non-transferable. The GreaterRNBA reserves the right to decline any RSVP and refund registration fees at its discretion. A $25 no-show fee will be assessed to registered members who do not attend.

Our Professional Interchange events have evolved into vibrant gatherings where business professionals come together not to sell, but to inspire, share ideas, build relationships, and collaborate with peers they might not encounter at typical networking events.

Our events are open to the public not for transactional purposes but to experience the culture of our membership and to learn more about the association and all the benefits it has to offer businesses.

Please note: This is a professional event, so we kindly ask attendees to dress appropriately. We request that men avoid athletic wear and opt for business casual attire, including collared shirts. We ask that ladies avoid crop tops, ripped jeans, or revealing clothing.
