The calendar shows the topics for 2023. Each two-day webinar can also include live and follow-up cases, related to the themes of the event. Ton will continue to give guidance on using blood-test results to influence our prescriptions, and also teach us about using orthomolecular supplements to enhance our homeopathic remedies.
At all webinars where someone is asking for guidance on case treatment a detailed timeline should be provided, so Ton can readily see what the case issues are and so give his advice more easily.

‘Intervision’ meetings will continue as wanted, both as smaller meetings in various time-zones and as fuller meetings internationally. Please give your ideas and feedback on these meetings!

The webinars will be as interactive as possible (and also secure), as by using Zoom for Meeting the presenter can see and talk to those attending. Questions can be asked via the raising-hand facility at question times.

The webinars will start at 1000 Amsterdam time (CET), with a break 1115-1140; the second sessions will run 1140-1250. The lunch (or breakfast or supper) break will run from 1250 till 14.15 (to give time for eating and a little exercise perhaps). The third sessions will run 1415-1525, with a break till 1550; the final sessions will be 1550-1700.

The first two sessions will suit countries from eastern Europe to Australasia but not be good for USA/Canada. Our third and fourth sessions will be fine for USA/Canada to attend live but will be a bit late for Australasia. (The afternoon sessions are not a repeat of the morning!). The longer breaks can also let us rest our eyes and move about a bit during the day. There will be a recording available soon after each day, to watch but not to download – but subject to the usual rules of confidentiality.

Everyone attending the webinars should have some familiarity with Ton’s system. It’s very advisable you have studied the book ‘Fighting Fire with Fire’ by Ton Jansen before the seminar, and a good idea to have read Human Chemistry part 1. These books are available to buy from or from this website.

Please register by emailing Roger Savage at the address below. The fee and payment arrangements for this year’s series of webinars will be sent by email, but payment links are on this website.  This is a grand opportunity to study with Ton from your own home!
