Temporary closure of practice

After 18 years in the Netherlands and 13 years in my practice in Amsterdam I’ll be heading out for a new adventure in Tanzania in the summer of 2023. I’ve been offered a position as chiropractor and clinical supervisor with an organization called “Pos+Abilities”: www.posabilities.org. At first, it’s a year contract, where I’ll be working as chiropractor in a hospital and village clinics; I’ll also be supervising younger colleagues during their volunteership and perform a variety of public health activities. My last month in the practice will be April 2023, and I’m leaving for Tanzania end of May.

To ensure continued good chiropractic care, I’ve been in touch with a number of trusted colleagues. Below you’ll find a list of recommended practices – have look at what works best for you, and I’ll advice you personally when we see each other next.

I’ll keep all files in a safe environment, even when I’m in Tanzania. When you make an appointment with one of my colleagues and they would like to obtain your file, have them email me and I’ll make sure they get it.

I plan to keep my website up to date with news from my new surroundings – feel free to check in once in while on www.tonner.nl.

It has been a pleasure and honour to take care of all of you in the years gone by. You will do well, also with your new chiropractor. It might not be exactly the same experience that you had with me – it might be even better!

Stay healthy, keep taking your D vitamins.

Best wishes,
