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.

Do you join us?

"We are looking for people willing to help by, for example, answer questions for people who are less good in speak or write a foreign language. When you live abroad and speak, in addition to Dutch, German or English, also Polish, Hungarian, Spanish, Italian or any other foreign language, we seek your help for people who live in these countries and have problems with running a test or with the treatment of, for example HPU. Often these people can’t find help locally and they are designated on a foreign language. Sometimes they find completely wrong information. Or come in the hands of people who are just out of their money. Would you like to translate an email now and then to Dutch, German or English, so I can answer, and then translate the answer back to the language you master or your native language, you can help this people. If you would like to do, please sign up."
We are for a better world.
