KEAC Parkstad

Here you find information about the activities that take place at our Centre and useful links about health, disease and nutrition. The KEAC is located on the Petrus Dorrstraat in Kerkrade, part of Parkstad Limburg.

A good cooperation both within the Centre as with the healthcare facilities in the Netherlands and the rest of the world is essential and means optimal care for each patient over the world. For 30 years the KEAC is worldwide a global understanding.

The KEAC organized the World Allergy Congress in Hoensbroek Castle and gives the annual refresher training to medical doctors both in and outside the Netherlands. The central idea: a comprehensive approach to disorders, questions, wishes or complaints by patients has remained all these years.

We aim to be a modern practice with all the possibilities that the internet offers.

Would you like to join us?

We are looking for individuals who are willing to help answer questions for clients who are less able to speak or write a foreign language. If you speak Polisch, Hungerian, Spanish, Italian or any other foreign language, in addition to Dutch, German or English, we are seeking your help to assist clinets living in these countries who may be having problems either carrying out a test or following a treatment e.g. HPU. Often, such clients either cannot find help locally, the correct information, or are afraid of being over-charged by unscrupulous companies.
If you are interested in helping, you can be designated to a particular language. If you are able to translate emails from this language into either Dutch, German or English, so that Dr. Kamsteeg is able to respond to them, and then translate his response back into the language you master or your native language, you can greatly help these individuals.

Together, we are striving for a better world.
