About us

Our CEO, 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 currently 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.

We’re multi award-winning, with accolades including ‘Outstanding Business of the Year’ at the Dental Industry Awards for 4 consecutive years (2017 to 2020), as well as nationally recognised awards within many of our individual practices.
