What COSS does

COSS – Clínica Odontológica San Sebastián is a privately held, multidisciplinary dental clinic chain headquartered in Santiago, Chile. Founded in 1945 by Dr. Amador Charad and Dra. Elena Dihmes, it now operates two physical locations — El Golf (Las Condes) and La Dehesa (Lo Barnechea) — equipped with 18 dental chairs, two Ministry of Health-certified operating theaters, a Central Sterilization Center, and an in-house Oral and Maxillofacial Radiology Center featuring 2D/3D Cone Beam CT and low-radiation digital imaging. The clinic offers 11 dental specialties (general dentistry, orthodontics, pediatric dentistry, periodontics, occlusion/TMJ, endodontics, implantology, oral surgery, aesthetic dentistry, oral rehabilitation, and radiology) plus add-on services including 24/7 emergency care, conscious and nitrous-oxide sedation, fonoaudiología, and a recently launched home-care dental service for mobility-limited patients.

COSS generates revenue on a fee-for-service basis across its specialties, with quote-based pricing that is not publicly disclosed; it runs promotional discounts such as a 20% Saturday rate on radiographs. Its go-to-market is direct-to-consumer, relying on a multilingual website (coss.cl), content marketing via blog and social channels (@OdontoCOSS on Facebook, Twitter, Instagram), patient testimonials, and an online booking portal (dentalsoft.cl). Patient segments span individuals and families, children and adolescents, seniors, and home-bound patients in the Vitacura, Las Condes, and Lo Barnechea communes.

The clinic remains family-led: Dr. Jaime Charad Dihmes, son of the founders, serves as Medical Director and Founding Partner, supported by a multidisciplinary team whose credentials span Universidad de Chile, Pontificia Universidad Católica de Chile, Universidad de los Andes, Georgetown, Paris VII, and a Universidad de Zürich exchange via the affiliated Fundación Apolonia. Ownership is private with no external institutional investment, funding rounds, or public listing disclosed; the business is operated as a fee-for-service clinical practice rather than a venture-backed or PE-backed entity.
