Our journey spans more than half a century.
It has always been our priority to make healthcare accessible and convenient for everyone. That’s why we keep investing in technology and in the continuous improvement of our services, to ensure that our clients receive fast and accurate results and unparallel treatment.

With new sample collection units, laboratories, and clinics across the country, we are now closer to the communities we serve. Today, we have around 400 sample collection units, central laboratories in various regions of the country and a main laboratory in Lisbon (CORE), a benchmark in healthcare technology.

Besides our laboratory expertise, we focus on Médical Oncology to ensure patients have access to the latest technologies and cancer treatments, providing them with the greatest possible comfort. Our scope also includes Fitness, with our first space opening in Restelo, Lisbon.

Despite our growth, we remain committed to a welcoming and attentive approach, providing a 360º healthcare service based on prevention, diagnosis, and treatment. At Joaquim Chaves Saúde, we consider ourselves to be more than a healthcare group. We are dedicated to improving and humanizing the health and well-being of all those we serve.


We started out a very small team. More than 60 years later, we are around 3000 people!”

Dr. Joaquim Chaves, founder of JCS, recalls the start of the company. The laboratory opened in the 60s in Mafra and lay the foundations for the brand’s success.
