Connecticut's Premier LGBTQIA+ Gala!

One Big Event

We’re rolling out the blue carpet for our 24th Annual One Big Event — Connecticut’s premier black-tie gala celebrating LGBTQIA+ health, wellness, and community. This unforgettable evening brings together allies, advocates, and changemakers like you for a night of celebration, connection, and impact.


Since 1983, The Health Collective has provided compassionate, affirming healthcare to LGBTQIA+ people and other communities across Connecticut. From HIV prevention, STI testing and treatment, and vaccinations to comprehensive dental and restorative care, our work helps people access the services they need in a place where they are seen, respected, and treated with dignity.


Your support makes this possible. When you sponsor or attend One Big Event, you’re not just joining a celebration — you’re becoming One Big Reason we can continue providing lifesaving and transformative care to our communities.

This year’s One Big Event is Saturday, November 14, 2026, at the Hartford Marriott Downtown! Click below to purchase tickets and learn more about everything this year’s event has in store!

A Message from our OBE Chair


Being the chair of OBE for over 20 years has shown me the power and dedication of our community, our allies, and families. The obvious intent of OBE, is to raise funds that support our work and mission.


One Big Event is also a great way to engage with the community, see old friends, and make new ones. When you support One Big Event you become a stakeholder in our mission, work, and in another human's life. This is the power in supporting One Big Event. I look forward to seeing you all there.
