We hired for our wedding setup and cleanup, and hiring them was hands down one of the best decisions we made for our big day! From start to finish, they were on top of every single detail. They worked seamlessly behind the scenes to make sure everything looked perfect, and at the end of the night, they handled cleanup so efficiently that we didn't have to stress about a thing. Beyond their total professionalism, they brought such kind, positive energy that by the end of the night, they felt like family. We are so grateful for their hard work and couldn't recommend them more!

David and Kim were able to provide waitstaff for my event of 60 guests. The ladies kept going the whole time they were here. They cleaned tables, guided guests to buffet. Kim was also kind enough to take pictures and videos that was not expected. Thank you so much!

We honestly can’t thank the Black Diamond team enough for all of their help at our wedding. Their servers worked so hard throughout the event and played a huge part in making everything come together so smoothly. We really appreciated how helpful they were from start to finish. We’re extremely grateful for everything they did and would definitely recommend for any wedding or special event!

Isabella was an excellent bartender and Asailia were a huge help for my son’s recent 16th birthday party. They had a great attitude and were able to help with many different tasks

David and the entire Black Diamond team were exceptional throughout our event. My wife and I hired David and a staff of 4 to serve at our wedding. From start to finish the staff was amazing. They not only did their job well, they interacted with guests, ensured that my wife and I were okay throughout, and even showed us some of their dance moves. After the event, they did a superb job cleaning up and checking with us to make sure they did everything properly. I absolutely recommend hiring David and his team for your next upcoming party or event. They did not disappoint one bit. From the bottom of our hearts, thank you David for a job well done.

Great Bartending & Catering exceeded my expectations! The service was professional, organized, and extremely friendly from start to finish. The drinks were amazing, the presentation was beautiful, and they kept everything running smoothly throughout the event. Guests constantly complimented both the bartending and the food. They were punctual, attentive, and made the entire experience stress free. I would absolutely book them again and highly recommend them to anyone looking for quality service for their event!

I had a party for my son last weekend and we had the best experience with our bartender Joshua.He was so awesome and personable, and made everyone feel comfortable right away. What I appreciated most was how he took full control of the bar so I didn’t have to stress about the alcohol at all. Everything ran so smoothly and our guests loved him. I would definitely go through black diamond bartending again, David was quick to answer anytime I communicated with him.

Our event was a casino night bachelor for my son. Our bartender was Kmia. She was a young lady that was on time, professional, easy going and extremely friendly. The entire group thought she was very helpful.

Sergio S.Oct 2019

Aside from being late they were unprepared! I was to have 3 drinks made from the liquors I was asked to get as they were supposed to be special drinks for the night. Halloween themed and which should have been easier for the server. There were no signs indicating this to the guest and the bartender had no clue as how to make what we had planned. He kept looking back at the phone messages for what the “drinks” Contained. I tried to help by guiding my guest to what to order using my cellphone. Yeah I was not impressed and probably won’t hire them for the coming events. Wish it would have worked out better!

David and his team tended bar for my wedding and we had a great experience. I was the bride so I didn’t really get to remember a lot of the big day but I heard nothing but good things from my friends and family. David was very accommodating and SUPER responsive which is what I appreciated the most. I texted with him very often before the big day to figure out the menu and how much of everything I would need. They were very reasonably priced and the fact that he brought 2 other people to help out was beyond amazing... if you want someone to take care of your event, he’s your guy!!! Thanks David!

We hired Black Diamond bartending for our speakeasy party! Aaron was awesome. He came early, set up, and cut up the fruit and garnishes we provided. We created an unusual drink menu with a variety of theme drinks for our speakeasy and Aaron did great. He was professionally attired and ran his bar efficiently. No complaints at all. Having a pro tend bar was one of the highlights of the party. I observed Aaron even jumping in and cleaning up spills when they happened. Just a great job overall! Five ⭐️⭐️⭐️⭐️⭐️ all the way!
