The Mansion truly is a way of life. We share this world, it's all about letting go. Taking risks. Opening your heart.

It's where CEOs inspire their employees. It's where business associates and friends meet for drinks and sweets. It's where artists and authors find their Muse. It's where families gather for Sunday brunch. And it's where the music plays on, beyond forever.

At The Mansion we believe if we are true to your vision, committed to your path and willing to share, we all can achieve things beyond what we know.

We encourage being yourself, support creativity and embrace passion of expression.

Of course you will want to check with your host if you are coming for a private event. So, whether it is flowers in your hair, business attire, a feather boa or your favorite sports teams colors, feel free to wear them here... all we ask is that you don't come nude!

Did you know?
we have curated rotating exhibits through our corporate art lease program at children.s hospital, the imf, the world bank, the us capital and the white house

If you are trying to fit in everything when you come to DC, you can fit literally everything in one trip to the O Museum. Shopping? Just about everything you find in the decked out rooms is for sale. Games? They have a pool table, pinball tables, and more.... you just have to find them. Get a drink or snack? They have great cocktails. History? Yep! See Rosa Parks' room as well as a room dedicated to John Lennon. This is just a few of the 80 rooms you can see. We were hoping to blitz through them, but it was more fun to stop and look around carefully at all of the interesting things. There was even Judaica! The staff was warm, personable, funny, and helpful. This would be a fantastic experience for kids. There is also an elevator, making most everything handicap accessible. The direction video is also signed and available in multiple directions. They thought of everything! I couldn't recommend this highly enough. I couldn't believe they also have rooms available for reservation. Someday, I hope to do this.
