2018 Wedding Special

Corporate Events

Castleton Banquet and Conference Center is an excellent choice for corporate seminars. It’s a multi-functional building that provides you the privacy that you need for your corporate event. Castleton is perfect for a one-day, off-site training where your company can build in a little fun along with its business.

Castleton can give special touches to corporate off-site meetings, such as trade shows, seminars, board or sales meetings, and continuing educations. Rooms can accommodate groups from 8 to 800.

The lake ambiance lends more than just scenery. Summer offers a beach setting for clambakes; winter makes ice-skating a possibility. If the occasion, for example, a customer or employee appreciation day, calls for more relaxation.

Castleton’s grounds lend themselves to walks during breaks and at mealtime. Our guests have the privacy that one might not enjoy at a hotel. The privacy of the setting may make it possible for an informal meeting or training session to move outside during inviting weather. Indoors, seminars or conferences may be held in quiet rooms equipped with viewing screens, easels and white-boards for presentation needs. Audio/visual equipment is available upon request. Fees are based on the type of equipment and number of days required.

All the food is prepared on site. Castleton has ample breakfast, lunch, dinner, and break menus to suggest items. However, the staff is happy to tailor a menu for specific needs.

  • "Thank you so much. I have to say that you and your staff are absolutely wonderful! It is so easy to have our meetings there just because you all make it so effortless. Everyone is so helpful and accommodating, and all of our attendees loved the change up for the schedule, the space and the food. Also, your suggestion to have the appetizer table out in the foyer was terrific! I would specifically like to call out the gentleman who served as our bartender. He has been at the last couple of meetings I have had there, and he is just so helpful and friendly. He even offered to pull my car around because it was raining as I was packing up. That kind of service-minded business is long gone in many businesses, and I just wanted you to know how special you all are and how much I appreciate your help to pull these meetings off each year."
