    Best Decision Ever!!!

    Choosing DeSeversky Mansion was the single best decision we made during our wedding planning journey. Being a covid bride and having to reschedule our wedding a couple of times from 2020 was extremely stressful and Dana, the event and sales manager, ensured we were accommodated from start to finish. Dana was incredible and our saving grace throughout every hurdle we came across, she was everything and we are forever grateful for her.

    Initially, it was important that we chose a venue that hosted one wedding at a time and I'm so excited we did. Not only did Deseversky make us feel like our day was important, they knew us by name, they were extremely responsive with any questions, they helped us with literally anything we needed and made us feel like our day was safe in their hands. The grounds are breathtaking and make for incredible photos, the mansion is beautiful in every way, the staff was incredible and the attention to detail was unmatched. The food was a-may-zing and my guests still talk about the abundance of great food and drinks. My husband and I are both of Caribbean decent and they even accommodated for traditional dishes that our important to our culture. My guests have told me repeatedly for months, it is the best and most fun wedding they have ever been to. My guests have also told me repeatedly, that we set the bar and they compare all events to ours!!! After all the stress we went through, hearing those comments made everything worthwhile and we have Deseversky to thank. After the big day, there's always things we would have changed, but I would choose Deseversky every single time, without hesitation. They are stuck with all of our venue needs moving forward, lol, and I'm so happy they are forever apart of our magical day! Thank you to Deseversky, Dana, and all the staff ❤

    Dream Wedding Venue - Classic, Historic, LI Venue

    If you're looking for a unique, truly classic Long Island wedding, this is YOUR VENUE. Not only is the property gorgeous, with SO MANY amazing photo spots, but the staff is amazing. We postponed 3 times due to Covid and throughout it all, Dana and the de Seversky team were responsive and accommodating. The main draw of this venue is that it is non-traditional. Your guests can roam the grounds, step out for some fresh air, explore the different rooms in the mansion... we loved that it was a unique set up and something different. The food is INCREDIBLE as well. We loved our cocktail hour options and our guests raved about the dinner.

    Can't recommend De Seversky enough!
