Florianópolis health-sector branding and marketing studio for doctors and clinics
About Sigma Health
Sigma Health is the health division of Sigma, a marketing and branding business with an office on Avenida Rio Branco in central Florianópolis, Santa Catarina. It is a strategic medical marketing firm that builds brands for doctors, clinics, hospitals and other health businesses. Its catchment covers Florianópolis, Tubarão and Criciúma, other towns in Santa Catarina and clients elsewhere in Brazil. Projects can run in person, remotely or in a hybrid format.
Laizi Demos is its CEO. She spoke at the Fotona IEM 2026 event. The company does not publish a founding year or a headcount. Its LinkedIn presence runs under the name Sigma Marketing Digital e Comunicação. It also has work linked to medical congresses and aesthetic medicine events, including SBD-SC, AMWC Japan, IMCAS Paris and KoreaDerma.
The agency uses a six-stage method: diagnosis, strategy, creation, execution, monitoring and optimisation. Services can be bought one at a time or combined into one plan. The menu covers monthly marketing retainers, photo and video shoots, paid traffic on Google Ads and Meta Ads, visual identity, branding, websites and landing pages, growth work, clinic launch support and training for receptionists. A paid-traffic-only option is offered to doctors who make their own content. Search visibility is handled mainly through websites and landing pages, and the team has published an article on local SEO, reputation and the patient decision journey. No separate Google Business Profile or link-building service is listed.
The client list is mostly medical rather than dental. Logos shown include Acore cardiology, Clínica LiBô, Instituto Neuro Wollp, Gabriela Zanette Dermatologia, Back to Basics Oncologia, Grupo Baía Sul, Clínica Carreirão and Clínica Don Braga, along with several individual doctors. Featured cases include branding for Acore Cardiologia and a visual identity for Clínica LiBô. The company also hosts sites for clinics such as Higiia, a plastic surgery and aesthetics centre in Florianópolis, under its own domain. Its totals are more than 100 websites, more than 200 medical brands, over 300 photo and video shoots and over 3,000 clients impacted.
A dental practice would fit best if it wants a full brand build, a new website and paid campaigns from a health-only team, or support opening a new clinic. Practices that mainly want ongoing technical SEO should confirm the scope first, because few details on that work are published. No prices are published, and the entry Plano Start bundle of a visual identity and a landing page is quoted on request.
