About Medical Service CSL
Private Medicine with a Human Touch
A rapid-response medical service built for Los Cabos — for its residents, its visitors and the people who host them.
CEO – Medical Director
Meet Dr. Grimaldo
Dr. Raúl Alejandro Grimaldo Chávez graduated as a medical surgeon from Universidad Lamar in Guadalajara, with further certifications from UNAM, the American Heart Association and other institutions. His early career included service as a rotating physician at a regional military hospital and as an aviation medic for the 5th Military Zone in Zapopan, Jalisco.
For more than 15 years he has practiced general and emergency medicine in Los Cabos as founder and medical director of Medical Service CSL, serving as trusted hotel-zone physician for resorts such as Pueblo Bonito Los Cabos, Club Cascadas de Baja, Palmilla, Cabo del Sol and many villas and residences across the corridor.
Beyond the practice, he has taught anatomy and physiology at university level, published research in pediatric neurology, served his community without profit in several catastrophes, and cared for children with terminal illness in ways that go beyond medicine. Patients remember his warmth, reassurance and genuine willingness to help.
“No person shall deliver men from pain, but much will be forgiven who make them reborn the courage to stand.”
Our Mission
The patient is the focus of everything we do. We understand how difficult it is to face illness far from home — so we bring fair, warm and adequate medical attention directly to your hotel room, villa or residence, with the satisfaction of feeling at home during your stay.
Our Vision
Visitors to Los Cabos often don’t know the quality medical care available here, which leads to lost time and delayed attention. We work with quality service and prompt response, connecting doctors, pharmacies, nurses, paramedics, medical equipment and emergency services into one network — so every patient gets the best attention and a speedy recovery.
A Complete Prehospital Team
Medical Service CSL brings together physicians, paramedics, emergency medical technicians and nurses — all with more than 10 years of experience in the tourist zone, in life-risk situations, common illnesses, catastrophes, humanitarian service and large events. Our portable intensive-care units let us deliver advanced life support wherever our patients need it.
