Founded in Barcelona in 2009, Diente Sano is a family-founded dental clinic led by Olga Gurova, a practicing dentist with prior experience in Moscow and additional professional training in Spain. For 17 years, the clinic has provided comprehensive dental care through a combination of in-house expertise, invited specialists, and local laboratory partnerships. Rather than scaling into multiple locations, the business has focused on quality, patient trust, and continuity of care — building a sustainable healthcare practice rooted in personal reputation and long-term relationships.
