The De Seversky mansion and its employees were incredible from start to finish.Sent on 03/16/2017
Jessica was the most professional, flexible and understanding sales rep I've encountered. With both my husband and I being in sales it was so refreshing not to feel like I was being sold on an idea but more so educated on the different options and offerings with no pressure added. She answered every question with the upmost honesty and expertise. She also stayed for the event until the very end which was completely unexpected - even helped us bustle mid way through! She was truly invaluable to the process.
Jackie, our maitre de, was hired on a bit after signing our contract. I am admittedly a control freak with a habit of meticulous planning and was uncomfortable with the idea that I didn't know her going in. As I went for my final appointment Jackie exceeded my every expectation. She was so down to earth and easy to talk to. She understood my vision and took note of all of my intricate details. She even asked a few questions that I hadn't though of previously. The night was executed flawlessly.
Joan, the bridal attendant, was the sweetest and most thoughtful god send. She greeted us at the door with glasses of celebratory champagne and before I could properly thank her was fixing my train and my veil so that the photographer could capture the moment. She was like superwoman and flash combined - she was everywhere without me ever noticing. She was stealth with grabbing food for dinner and conveniently placing it wherever we were on the off chance we could grab a bite! She even went back into the kitchen for some extra buffalo chicken rolls (MUST HAVE)
Speaking of food, it was first class! Not only was it delicious but also beautifully displayed. My sister in law is a chef and even she was blown away. We had a Gatsby style wedding with plenty of variety when it came to the menu and everything was superb. People are still raving about the spread!
Simply put, it was perfect!

The perfect Day
My wedding could be described as a perfect fairy tale. As a little girl you always dream of this day (damn the patriarchy am I right? haha) and on Saturday I felt like a princess. It could not have been a better day. I have no words to describe how incredible the staff is. I kept hearing from my guest how amazing the attention was and I have to agree. Melissa, the bridal attendant made sure everything went perfectly, she was an amazing Fairy god Sister (shes to young and beautiful to be a fairy godmother haha). She remained calm and always had a solution to even the smallest of problems. (With champagne!)Sent on 12/26/2018
The staff there are worth their weight in gold.

Wedding venue of your dreams
The de Seversky Mansion gave me my dream wedding. My friends and family seriously refer to our wedding as the "Wedding of the Century," and that is all due to the unbelievable staff at the de Seversky Mansion. There is so much to write about the de Seversky Mansion so I will just hit some of the ultimate highs. First, everything was so organized the day of the wedding. From the ceremony, to cocktail hour to dinner and dancing- there was never anything I had to worry about.Sent on 01/12/2019
Second, the Mansion is so well-kept, clean and just stunning. There are very few venues that you get to have all to yourself. We did a European-style wedding and got to really spend time in all different parts of the mansion. While the pictures look incredible, de Seversky is even more speculator in person.
Third, the staff is top-notch. Jessica Wontz is a rockstar and bent over backwards to make sure my day was perfect. She would talk to me on weekends and calm me down as I freaked out about wedding prep. Jessica is also extremely organized and professional. She really became a friend throughout the process! We feel so beyond grateful to have her part of our wedding planning process. Also, Jose, our maitre, was the absolute best. He made sure that everything the night of wedding was perfect. He was so professional and really ran the Mansion like a well-oiled machine.
Fourth, the FOOD. No words to describe how delicious it was. This is not wedding food, it is seriously a gourmet meal. When our friends talk about our wedding they always say, "the food was incredible and there was so much of it!"
I could go on and on, but overall the de Seversky was everything I wanted and more. They are an unbelievable wedding venue and if you can secure a date, book it! You will have the wedding of the year!
