I love this cantankerous old man. And not just because he has put his finger up my butt and had to touch my junk.

I went in for my annual re-check. I hadn’t realized that a year had already passed. I received a couple of text reminders that I appreciated very much. Filling out the forms online was super easy. When I arrived I was warmly greeted and the wait was short and pleasant. The office staff, nurses and assistants are all friendly and professional. Dr Sender is patient and kind. He explains everything very well. They all have really neat keyboard for their computers too, that was fun.
