Meet the Team

Duncan J Park BDS (Hons) MFDS RCS (Eng) MMedSci (Dental Implantology)

Principal Dental Surgeon

GDC no. 82373

Excellence in any job comes from having a real desire and passion for the work, and this is something that Duncan has in abundance. This, combined with superb clinical standards, results in the best possible treatment for all his patients.

Duncan qualified from Sheffield University in 2003 with honours and the prize in restorative dentistry. His surgical skills were further developed by holding SHO and staff grade posts in hospitals including Sheffield, Barnsley and Chesterfield.

One of Duncan’s main interests is implant dentistry. Having completed implant training courses in Sheffield, he followed this up with the extensive post-graduate implant master’s degree at Sheffield University, so he is highly trained and experienced in implant treatment.

Updating knowledge is vital to keep on top of an evolving and ever-developing profession, so Duncan attends regular courses and conferences, as well as being a member of the Association of Dental Implantology (ADI).

Due to his expertise, Duncan accepts referrals from other dental practices for implant treatment, surgical work (e.g. difficult extractions and wisdom teeth), CT scans and IV sedation – types of treatment that would have traditionally been referred to a hospital. This in-house option can dramatically cut down on waiting times and the inconvenience of a hospital visit.

Most of Duncan’s spare time is taken up with his wife and four children, as well as walking his two hyperactive boxer dogs! He had to retire from playing rugby due to an injury but is now an enthusiastic spectator of the game.

Matthew Stephens BDS (Hons)


GDC no. 263989

Matthew is the newest dentist to be welcomed into our practice and is bringing with him a compassionate, professional and holistic attitude towards your dental care. With the smile and skills to make any patient feel at ease, Matthew has the ability to understand your concerns and offer a wide range of restorative and cosmetic treatments with an ethical and detailed approach. Matthew is always passionate about the dentistry he offers and has a dedicated and friendly demeanour towards all his patients whatever their age or background.

Having received a first-class undergraduate degree prior to graduating with Honours in Dentistry, Matthew has shown to be an avid learner and is keen to increase his knowledge and skillset further by completing a range of advanced courses. To highlight this, Matthew has recently completed a course in anterior alignment orthodontics and is qualified to deliver Invisalign treatments.

In his spare time, Matthew enjoys keeping up to date with dental journals, reading novels and spending quality time with his girlfriend, family and friends. He also has achieved a 1st Dan black belt in Shotokan Karate and enjoys baking up the odd sweet treat!

Coren Coucom-Smark

Green Square Dental - Dental Hygienest

Abbey Ashley

Dental Hygienist

Abbey qualified as a Dental Hygienist and Dental Therapist from the University of Sheffield with Distinction and has been a Dental Care Professional since 2010. After qualifying in 2013, she then went on to achieve certificates in Oral Health Education and Dental Sedation Nursing.

She enjoys treating patients with the latest Airflow® and Perioflow® technology to provide effective and gentle cleaning without the discomfort associated with traditional professional cleaning. Her training as a therapist also enables her to provide dental fillings.

Abbey has undertaken voluntary dental missions to Cambodia in 2014 and 2016 with the charity Dentaid where – as part of a team of dental professionals from the UK – she provided much-needed treatment and education to vulnerable children and adults from deprived populations who had mostly never seen a dental professional before and suffered from dental
disease and pain. During her time in Cambodia, she also gave international lectures at the University of Puthisastra to their dental students.

Abbey enjoys spending her free time with her three pugs and going to music concerts.
