A great evening at this year’s @thedoseum Birthday Bash! Thank you to the elected officials who joined us in celebrating.
Onyx was happy to sponsor today’s @metrosachamber Joint Economic Development and Government Affairs Council meeting.
The event was hosted by our client, @sanantoniozoo at its newest event venue, The Ralston.
We heard from Zoo President and CEO @mananazoo about the Zoo’s exciting new additions, including Congo Falls, and the significant economic impact the Zoo continues to have on our community.
Congratulations to @sanantoniozoo on the grand opening of the Brewer Ocean Conservation Lab!
This exciting new facility will advance coral restoration, conservation research, and public education. Thank you to the elected officials and community leaders who helped mark this important milestone.
Proud to have Onyx attend and sponsor the @metrosachamber State of the County Address. Thank you to our clients and the elected officials who joined us at our tables. We enjoyed the conversation around Bexar County’s continued growth and successes.
@cyrusonedatacenters hosted local leaders and industry partners for a tour of its SAT5 data center at Texas Research Park. Featuring presentations from Dan Diorio from the Data Center Coalition and Erica Estrada at CyrusOne, the tour highlighted the growing role of data centers in driving economic development nationwide and across Texas.
Thank you to our client, @cyrusonedatacenters, for hosting a great tour, and thank you to all who attended.
