The Active Amputee
I am Bjoern Eser, the founder of and the shaker and maker behind The Active Amputee. I am a father of three amazing children, a husband to an equally amazing wife, a thankful cancer survivor, an outdoor enthusiast, a passionate development practitioner and a very active above-the-knee amputee.
I have set up The Active Amputee as a resource page from amputees for amputees. It aims to inform, it aims to inspire, and it aims to engage. Nothing more and nothing less. It‘s as simple as that.
Sign up for our newsletter to make sure you don‘t miss any new articles, get additional information beyond what is published on this side, and learn about upcoming events and opportunities to be active and meet other people affected by limb loss and limb differences.

And you can read it tomorrow here on my blog. read more
