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.

                              What our patients say

                              "I've used various dentists over the years, and most have been very good, but Krishan Mistry at Holland House is by far the best I've ever seen. I usually hate everything about the dentist, but since I've been treated here, it's (almost) a pleasure to attend an appointment... Thanks, guys!"

                              "Laura Jones is a fantastic dentist, when I first attended I was very nervous, anxious and quite scared due to previous experience with a dentist. Laura made me feel so at ease, she really did make me feel confident about going to the dentist again! Highly recommend Laura Jones dental care! She really does care about her clients!"

                              "I have been a patient for some considerable time and am very happy with the treatment I have received. Very recently I underwent major root canal work experiencing no pain and would say that it was almost a pleasure!!"

                              "I was very nervous on visiting the dentist today as I didn't really know what to expect (root canal). I was immediately put at ease by Dr Wintle and her assistant. An hour later things were better than we thought. Thank you both for all your help and support. See you very soon!!!!"

                              "I had thought about having braces for years and after deciding to go for a consultation at Hereford Dental and Implant centre, I can not be more happy. Gursh and his team offered excellent care and service. After 12 months of treatment and aftercare I am finally happy with my smile!! I would definitely recommend the clinic to anybody!"

                              "I was lucky enough to come across Haynes Dental Practise earlier this year, having decided to face my lifelong dental phobia. I cannot thank them enough for the fantastic advice and treatment I have received and continue to receive. I have totally had my faith restored in dentists and would highly recommend Haynes Dental Practise without hesitation to everyone"
