Colosseum Dental Group to enter French market by acquiring Dentelia


Colosseum Dental Group (CDG), the leading pan-European provider of high-quality dental care, has reached an agreement with Otium Capital, the current management team, and the founder and CEO Dr Alexandre Attia to acquire a majority stake in Dentelia, a rapidly growing high-quality dental care provider in France. Dr Alexandre Attia will retain a significant equity position and drive the expansion of the group across France together with the current management team. The acquisition expands CDG's footprint into France, the second-largest dental market in Europe and fosters its position as the leading pan-European dental care provider with more than 300 dental practices in nine countries.

Dentelia, headquartered in Paris, France, was founded by Dr Alexandre Attia and backed by Otium Capital, a family office managing the assets of French entrepreneur and investor Pierre-Edouard Stérin. Over the last two and a half years, Dentelia has successfully set up and managed 14 clinics based on a standardised clinic development model enabling a rapid expansion. Dentelia maintains a significant greenfield and M&A pipeline for future growth in a yet unconsolidated market.

"We are very pleased to welcome Dentelia to the Colosseum Dental Group family.  Dentelia, as a leading dental care provider in France, is the perfect partner for CDG to enter a significant market in Europe. Its focus on quality care and patient-centric service models supports our strategy excellently. Dentelia will become a valued member of CDG, and we look very much forward to Dentelia contributing to our international collaboration within the Group", said Stefan Nilsson, CEO of Colosseum Dental Group.

We are very proud to become part of Colosseum Dental Group. The tremendous opportunities of the French market, combined with the rapid evolution of our profession, require a strong partner with vision and expertise. Its international perspective, its long-term strategic commitment and its dentist-oriented approach make CDG the partner of choice for Dentelia. The partnership will support Dentelia’s smart growth while keeping an innovative and quality-oriented approach to ensure sustainable value for our patients, team members and shareholders”, said Alexandre Attia, CEO and founder of Dentelia.

The transaction was completed on 20 January 2021. No financial details have been disclosed.
