“We held a multi-day event at the National Union Building. The spaces and rooms are gorgeous - so much more character than most conference venues! The staff were attentive and responsive to our every need. We would highly recommend the National Union Building for meetings, events, conferences, parties, and receptions!” - Siri E.
We recently held our wedding ceremony, dinner, and reception here and had a wonderful experience. Event coordination, space options, catering, and bar service were great, and everything went off without a hitch. The staff was very friendly and helpful, and left us feeling like they genuinely cared about us and the success of our event. National Union Building has my highest recommendation for any event. - Jeremiah D.
I work for a company and we held an event at National Union Building this past Thursday, February 13th. I couldn’t be more happy with all of the staff that assisted in making my event a success. The team had a beautiful display of food, not to mention the food was delicious! Thank you so much for a wonderful first experience & we are looking forward to our next event!” - Tara Rosen
We had a special company event here and it was great. From the small details to the catering option, it was great. The staff were so kind and felt like they were invested in our event too. Enjoyed the space and will absolutely use it as our "go-to" special event space. - Sara Gibson
“The National Union Building events team has done it again. We received red carpet treatment from the beginning of the event until the end. Sean managed to be everywhere all at once and offered suggestions to make our event even more special. Our guests were in awe of the event space, and we are looking forward to returning for our next event!” - Michellay
