About us

Our founder and group chief executive, Sam Waley-Cohen, founded Portman Dental Care in 2009 with the desire to be the best rather than the biggest privately-focused dental group. Culture and values are critical to us, with a simple ethos at our core to treat others as we would want to be treated ourselves.

Portman Dental Care have 200 dental practices across the UK, Ireland and Benelux, including 16 orthodontic Portman Smile Clinics, caring for over 700,000 patients. Our practices offer a range of specialist, private and NHS dental care services, and are focused on continual development both in clinical skills and innovation.

Portman Dental Care joined forces with Dentex Health in 2023, to bring the best of both organisations together into one new business. Together, PortmanDentex now provide dental care to over a million patients every year. That’s over 370 practices across the UK and Ireland, with more than 2,400 clinicians and 4,500 practice colleagues providing dental care for our 1.5 million patients.
