Devon Huston-Aljazazy2 years agoHighly, highly recommend Trillium Event Center for any of your events! I can’t thank Randall enough for how much work he put into our wedding. He was so professional and helped us through one of the most stressful events that people have to go through! Everything went so smoothly and was so beautiful! The food was absolutely AMAZING! It’s the perfect set up for anyone looking to have a wedding and reception all in one place! Thanks again, Randall! It was perfect!
Stacey Scharphorn9 months agoPerfect all in one venue, had our wedding ceremony and reception there. The staff and Randy were great! The whole night went off perfectly and so smooth! All our guests loved the food provided, I would recommend this venue to any bride to be!
Susan Betza year agoWhat we got vs what we were told they would do. Everything was delicious but when you have a "wow" thing planned and pay extra for the components of it. Well it was extremely disappointing Great to work with. Snaffo on the main menu but misunderstanding on both parts. Still very delicious just make sure you get all your left overs if you want them Very accommodating and gave us extra time to set up etc Great venue but I'll be much more specific next time
Klaire Purchase3 years agoTrillium events is a beautiful center to throw your next celebration. I have been to this event center on multiple occasions. High School prom, a wedding, a hunting\rifle show. On All occasions The event center was decorated to the tea and clean very fresh. There is a lot of parking at the center you can have a huge party. There is many bathrooms at the event center you will not have to wait in a line most likely. The event Hall itself is extremely large well-lit and has a few windows. Smoking outside the front of the building is permitted. You can serve or sell alcohol at your event. There is a few different rooms if you want a couple things sectioned off. It's located fairly close to the highway about a 5 to 10 minute drive.
A Younes4 years agoBook here if you're considering! Just hosted my mom's wedding at this beautiful venue. I live out of state and helped plan from afar. The venue is even more beautiful in person. Randy is the owner and was there all day working hard to make the even perfect. He always helped with a smile and patience. The floor crew was amazing, too. They kept busy and we're super attentive to taking dirty dishes, answering questions, helping with ending clean-up, etc. The crew working the buffet were pleasant and friendly. Even the kitchen staff were great - they allowed us to store all of our desserts in the fridge in advance. Compliments to the chef and kitchen crew: The FOOD WAS AMAZING. I rarely get seconds but I had to have more of the chicken! YUM. The bar was great, too. I was thoroughly impressed with everything!
