Our History

Reference in health, with an eye to the future, since 1959

Taking better care of people has been at the center of everything since 1959.
That same commitment still drives us to continue to innovate and improve society today.

Joaquim Chaves Saúde has been at the forefront of laboratory diagnostic since 1959, with a proven track record as a healthcare service provider.

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.

Dra.Natália Chaves

An entrepreneurial and visionary personality, her career was marked by a remarkable capacity for innovation and business development.

Her spirit of sacrifice led her to give up her vocation as a physiotherapist, and later as a doctor, to dedicate herself to the administrative and organizational management of, at the time, Laboratório Dr. Joaquim Chaves. It was during this period that the company consolidated its position in Mafra and became a benchmark in clinical analysis.

His story is an inspiring testimony to his courage and devotion to a project that he embraced wholeheartedly. Thanks to his determination, generosity, enthusiasm and commitment, Joaquim Chaves Saúde has become a benchmark in the provision of healthcare in Portugal.

Today, his legacy continues to inspire!
