Details
We’re Going Back to the Overholser Mansion!It’s been a couple of years since we last stepped inside the stately home of Henry and Anna Overholser—but the wait is over! They’re ready for us to return, and we don’t want to disappoint.
Built in 1903, the Henry Overholser Mansion is often called “the crown jewel of Oklahoma City.” Henry Overholser, known as the “Father of Oklahoma City,” built the grand Queen Anne– and Châteauesque–style home for his wife Anna and their daughter. For decades, the family hosted elegant gatherings within its ornate rooms, and today, much of the home remains exactly as it was over a century ago. But along with the furnishings and history… some say the Overholsers themselves may still linger.
Join us for a special paranormal investigation inside this iconic Oklahoma landmark. We’ll share stories of past encounters, give you access to our investigative equipment, and spend the night exploring the mansion’s mysterious side. We are capping this event at 16 guests.
Date: Friday, November 1, 2025
Check-in: 5:45 p.m.
Start Time: 6:00 p.m. sharp
End Time: 10:00 p.m.

We’re beyond excited to wrap up our Halloween season with an unforgettable evening alongside the Overholsers themselves.
A generous portion of ticket sales goes directly back to the Overholser Mansion to help preserve this beautiful location for years to come.

As much as we try to keep people arriving in groups together and investigating in the same group, sometimes that is not always possible due to size and other factors.
