Diamond Bar Community Center

Great place for seminar and small meeting. Clean and large space

Always a place to admire the valley. Sitting on top of a hill, you have a good view of LA and the nearby towns. The hike can be challenging if you are a beginner but pretty good for those intermediate walkers. They have a good community center that the residents can use or even for visitors. Clean restroom and friendly steal too.

Have visited Summitridge Park where Diamond Bar Center is located several times. However, I have not entered building. It is owned and operated by the City of Diamond Bar. A 22,500 square foot facility designed with a modern Craftsman style with banquet and meeting rooms. It is an ideal location for social gatherings, meetings or receptions.

I scheduled my event for September 2025 in June 2024. In January 2025, I received a notification from the center informing me that my event had been canceled due to a city project. This situation has caused significant frustration and inconvenience. I have already arranged for a mass and vendors for that date, for which I have made payments and provided deposits. Consequently, I was compelled to search for an alternative venue. Additionally, it is particularly aggravating that the return of my deposit for the venue may take four to six weeks. It is unreasonable that they canceled my event; they should have been prepared to refund my deposit within a week of the cancellation. I am perplexed as to why the process of returning my deposit is taking so long!

We love Diamond Bar Center! We have had the opportunity to work there several times over the years. Every year, every event we had a blank canvas to transform the space. As a wedding planner it makes my life easier knowing that the staff is amazing. We have worked with Monique, Evelin, Vanessa, and Sam. It didn't matter who we worked with, we always knew we were in good hands. It made the flow and logistics run so smoothly. Highly recommended and book in advance!

Traffic to and from was not fun, but the center is in a beautiful location, the building is modern and large enough for a big party.

Just was there this past weekend for one of my Sister's wedding! I love this venue, we had about 450 guests and it was more than enough room, and the staff is on point and very accommodating

My Daughter's Debutant Ball was amazing here. The overall turnout was just breathtaking. The staff worked out everything. The outdoor scenery was perfect for the photos. The kitchen was clean. Everything was cleared out & prepared for us. All year planning.
