Veterinarian Technicians & Assistants

Sandra Barbosa

Veterinary Assistant

Sandra's passion for the animal world led her to train as a Veterinary Clinic Assistant in order to be able to work with and for them.

In 2004 she started working in a Veterinary Clinic in the south of Spain. In 2018 she moved to Madrid, where she had the opportunity to join great teams of Veterinary Centres and at the same time continue her professional development. It is true that there are hard moments in this profession, but even so I wouldn’t change it for anything. The unconditional love that pets give makes everything possible, there are no limits or prejudices. Over the years, she has learned to be more patient with them. She has a special affection for felines. He finds them so fascinating and mysterious that it is impossible for him not to want to know more about them. So much so that she trained in Feline Ethology to be able to put all her acquired knowledge into practice. On a personal level, she loves to get lost in the countryside with her camera.
