Cham Fernando



Cham qualified from Barts & The London School of Medicine and Dentistry in 2007 and has worked in general practice for over 10 years. During that period he has broadened his skills by completing courses in Implants, Endodontics, Short Term Orthodontics and is now an experienced provider of Invisalign.

Cham is passionate about all aspects of dentistry and has a friendly and gentle approach to patient care. He likes to involve his patients at every step on their journey to straight teeth and shares their excitement as the treatment progresses.

He chose to provide Invisalign for patients as after researching different orthodontic appliances, Invisalign is a trusted brand that has enhanced the smile of over 5 million patients worldwide. Invisalign works via the use of innovative custom made clear aligners that straighten your teeth without the need for metal wires or brackets. Cham has helped many patients restore confidence in their smile using Invisalign.

Simon 1 240X300

Simon has worked in Dentistry for almost 10 years. He started off his career in Practice Management originally in Buckinghamshire and has managed dental practices both in the NHS and Privately.

Simon takes pride in his job as he likes to support and engage with people. He believes that in running a practice, patients are the primary focus. He endeavours to make sure each and every patient has a satisfying visit to the practice, one which is not rushed, where staff are genuinely interested in getting to know and care for each patient, as well as exceeding each patients expectations of coming to our practices.

Simon is particularly interested in Invisalign as he himself is currently using the aligners to help give him confidence in his own smile. He believes that as he is personally going through the treatment process, he is better abled to provide advice for patients thinking about Invisalign.

In his spare time Simon enjoys cooking different foods and learning new recipes as well as socialising with close friends and family.

Since moving back into the area he has started getting into gardening.

Harriet Shaw

Dental Nurse


Dentistry has always been a huge part of my life and is something I really enjoy. We have so many lovely patients here and it makes it a really wonderful place to work.

My aim is to help make patients aware of dental options and treatments that are now available at our practice. I always endeavor to try and make coming to the dentist a pleasant experience.

Invisalign is one of the treatments I love nursing for as you see each patient’s confidence in their smile grow as the weeks go by. A lot of patients don’t realise how simple the process can be and how quickly results start to show. It’s amazing to see patients who were once scared to smile, now feel happy in themselves to show their teeth off. After having clear aligners myself I can share my personal positive experience.

When I’m not at work I enjoy Fine Art and Photography. I’ve grown up in the local area and particularly love taking photos of our countryside in all its seasons.


We are based just off the main High Street in Olney in Cobbs Garden right next door to the main doctors surgery. If you are traveling by bus, the nearest bus stop is just 5 minutes walk from us.
