About GéroStim-Expertise
GéroStim-Expertise provides specialised home-based gerontology support, based in Cagnes-sur-Mer and operating across Monaco and the French Riviera, by appointment.
Mission
My mission
Providing support to better preserve remaining abilities: this is the commitment of GéroStim-Expertise. I support elderly people living with Alzheimer's disease, Parkinson's disease, or related neurocognitive disorders in their own homes, using non-pharmacological approaches.
My goal is to stimulate preserved abilities, encourage independence, and support the person's quality of life, whilst providing support to their family carers.

Values
My values
Respect for dignity
each person is supported with respect for their personal history, daily habits, and choices.
Personalisation
each programme is built around the person's preserved abilities and personal interests.
Coordination
I work in close collaboration with loved ones and home-care providers, respecting everyone's scope of practice.
Transparency
my services complement home help and do not replace medical acts or regulated nursing care.
