National dental group

Portman Dental Care is the fastest growing, privately led dental group in the UK. Its growth has been built on its reputation for high quality care and the strong relationships it has with its dentists and clinician community.


Success with a smile

  • Incorporated in 2009, the group had grown to 27 dental practices by the time we invested in 2014. We supported its continued growth and the group grew to over 75 practices across the UK during our investment, whilst still maintaining its reputation for modern clinical facilities, patient friendly appointments, friendly and caring staff and the highest clinical standards.

  • To retain these high standards, we supported Portman’s investment into IT, HR and quality management systems and helped build the senior team with a number of new hires, including a new chairman, COO and M&A director.
  • Following a successful partnership together, we sold the business to another private equity firm in 2018, with the Waley-Cohen family retaining a significant stake in Portman. Adam Holloway, Livingbridge, said, “Sam and the team at Portman have built a fantastic company which is now one of the shining stars of the sector. We are delighted to have played our part to help grow the business further and look forward to seeing the business continue to grow over the coming years."


“I would like to thank Livingbridge for their support over the last three years, during which time they have helped us grow to over 75 practices across the UK and establish Portman Dental Care as the fastest growing, privately focussed dental group in the UK, whilst retaining our core values of putting our people first and looking after our patients. ”
