the Adventures of Sara Cladlow

I am Sara Cladlow, a social consultant working in Washington, DC. I provide consulting, social training, and event services for both corporate and political clients. I also accept contracts for security investigations requiring a subtle touch.

The original 2020 eChallengeCoin sold out. But, it's back!

The 2020 eChallengeCoin REDUX is almost identical to the original. Thanks to the chip shortage, there is a small change under the hood. It is gold plated and 2mm thick, just like the original. It was not be possible to replicate the side plating.

The 2020 eChallengeCoin REDUX is available on my Tindie store!

If you already have the 2020 eChallengeCoin (or not) and want to read the story, Sara and the Deleting App is now available online.
