Principal Dentist

Jon Cowie

Qualifications: BDS, MSc, BA
GDC: 245635

Dentistry is my calling and I could not imagine doing any other job. As a Northerner from Sheffield, I qualified from Sheffield University in 2013 and since then I’ve continued to feed my passion for my work by training in complex reconstructive dentistry to rebuild worn teeth. I enjoy making the strongest possible tooth restorations look indistinguishable from natural teeth, helping my patients to have teeth that will hopefully last them a lifetime as well as improve the appearance of their smiles.

My other special interest is smile design – using my tooth restoration skills alongside the Invisalign straightening system to help my patients look and feel more confident with their appearance. I have completed an orthodontic diploma in ‘Clear Aligner Therapy’ – the highest level of training available for the Invisalign system – which has given me the experience to make smiles the best they can be.

In 2019, I took over Triangle Dental with Chris Read, the other principal Dentist. Becoming a practice owner has allowed me to put into practice my ethos for dentistry which is to provide patients with access to the highest quality care in order to find long lasting solutions for our patients’ dental needs. I also believe that good dentistry is as much about the patient as it is about treatment so I strive to ensure that all of our team creates a genuine connection with patients and makes them feel comfortable and at home in our practice.

I’m a family man and my favourite way to spend my free time is with my wife and two young daughters. As well as dental health, I’m very interested in full body health and wellbeing including exercise, strength training and pursuing a healthy diet – I even ferment my own food for a healthy gut!

Principal Dentist

Suzie Boulos

Qualifications: BDS, MFDS, RCS
GDC: 244343

I qualified from The University of Birmingham Dental School in 2013 before going on to gain my Membership of the Faculty of Dental Surgery with the Royal College of Surgeons. I have since worked in both hospital settings and private dental practices from Ascot to Guildford, before returning to my home village of Tilehurst.

Since joining Triangle in January of 2019, I have loved getting to know each of my patients, and ultimately I believe the better I come to learn your needs and your desires, the better I can ensure you achieve the level of care that you deserve.

I enjoy all aspects of dentistry but have a particular interest in oral surgery and cosmetic dentistry, with an emphasis always on preventative dentistry. I am also a trained provider of tooth straightening systems including Invisalign.

I am passionate about providing my patients with the most enjoyable experience possible as well as providing them with exceptional dental care. In particular, I love being able to help nervous patients and children to undergo the treatment they need, ensuring they leave the chair feeling well cared for, and of course, with a smile on their face. 

Away from dentistry, I love going to the gym, participating in various fitness events, cooking, long walks with our dog and spending time with family, especially since welcoming our daughter Hallie in the summer of 2022. 

As well as catching up with my existing patients, I always look forward to welcoming and getting to know any new patients to the practice, and hope to help address your dental concerns with a helping hand and a friendly smile.

Associate Dentist

Chris Read

Qualifications: BDS, BSc
GDC: 212435

After gaining my degrees in Biomedical Science from Southampton University in 2006 and Dentistry from Peninsula Dental School in 2011, I went on to complete two years in maxillofacial surgery as a senior house officer. This has given me the confidence to deal with a majority of surgical procedures which can be carried out in general practice. 

I have worked in a number of practices around the country before settling at Triangle Dental in 2016. Since then, I have developed my training in dentistry with a variety of courses focusing on my interests in general dentistry and oral surgery. In 2018, I developed skills in facial aesthetics with Dr Bob Khanna, allowing me to provide botox and dermal filler treatments and am currently registered with the International Academy of Advanced Facial Aesthetics (IAFFA). 

Outside of dentistry, I live with my wife and two daughters and enjoy travelling, skiing, swimming and flying when I can. 

Associate Dentist

Donna Judge

Qualifications: BDS, BSc
GDC: 83476

I qualified from the University of Birmingham in 2004. I joined Triangle Dental in 2013, having worked in private dental practices since 2006. I enjoy treating all aspects of dentistry with a preventative approach and particularly like showing patients that it can be a lot more pleasant than they anticipate. It is always so rewarding for me when nervous patients willingly return, with a smile, for more!

I am an Invisalign trained Dentist and enjoy being able to incorporate the straightening of teeth with cosmetic dentistry in a minimally invasive way.

I regularly attend courses to keep abreast of the current thinking in Dentistry and am a member of one dental study group, who meet several times a year and where I can participate in lectures from renowned world speakers.

Outside the practice, I am a keen crafter – dressmaking, knitting, making jewellery are a few examples. I am always on the look out for new crafts to try!  I also enjoy cooking, reading and spending time with my family.

Associate Dentist

Andrew John

Qualifications: BSc BDS MFDS RCS (Eng)
GDC: 229312

Originally from Cheshire I first completed a BSc in Biology from the University of Leeds and then went on to graduate from the Peninsula School of Dentistry with a degree in dental surgery in 2012. After dental vocational training in Plymouth I worked in hospitals as an Oral and Maxillofacial Surgery Senior House Officer in the Southwest and at the John Radcliffe Hospital in Oxford.

In 2016 I passed the examinations and assessment required to become a member of the Faculty of Dental Surgery, part of the Royal College of Surgeons of England.

I am passionate about general dental practice and ensuring that my patients are given the very best of care to achieve and maintain long-term oral health. In particular I enjoy improving patients’ smiles with minimally invasive cosmetic dentistry. I recently completed a one year certificate course in Cosmetic Dentistry and Advanced Aesthetic Restorative Dentistry which has enabled me to deliver functional and aesthetic outcomes using the latest techniques.

Away from dentistry I am a keen mountain biker and I enjoy spending time on the Cornish coast as often as possible.

Associate Dentist

Wilson Wong

Qualifications: BSc BDS MFDS RCS (Eng)
GDC: 295775

I absolutely love my job and I am passionate about truly listening to patients in order to deliver a bespoke oral health improvement plan that could help them achieve their long-term goals.

I qualified from Cardiff University and have worked in practices in Cardiff before joining the Triangle Dental Team. I am originally from sunny Malaysia and moved to the UK 8 years ago as I love the colder climate! =

I was honoured to be shortlisted as a finalist for the Best Young Dentist category in The Dentistry and Private Dentistry Awards 2022. Whilst I welcome these achievements, for me, success lies in how I make my patients feel and how I see their oral health improving.

Outside of dentistry, I love travelling and have done ice caving, glacier hiking and artic hunting for northern lights. I was not kidding when I said I loved the cold!

Root Canal Treatment Dentist

Justin Underwood

BSc, BDS (Hons), PGDip, MFDS, MClinDent, M Endo, AFHEA
GDC: 210724

I’m the dentist at Triangle Dental with a special interest in root canal treatment (endodontics), helping patients save their natural teeth and get out of pain as comfortably as possible.

I graduated from Cardiff University with Honours where I also completed additional research training and presented it at the International Association of Dental Research (IADR) congress.

I then went on to complete a postgraduate diploma in Endodontics, followed by four years of specialist endodontic training at King’s College London, qualifying with distinction and receiving the Pitt-Ford Prize. During this time, I also worked as a clinical teacher and lecturer, supporting and mentoring undergraduate dental students.

I hold Specialty Membership in Endodontics with the Royal College of Surgeons of Edinburgh (M Endo RCS), which is recognised as the highest qualification in the field, and in 2020 I was proud to be a finalist for Best Young Dentist at the Dental Awards.

What I enjoy most about endodontics is the precision and problem-solving involved — but most importantly, being able to relieve pain and help patients keep their own teeth. I understand that root canal treatment can feel daunting, so I always aim to provide care that is gentle, pain-free, and relaxed, taking time to explain everything clearly and make patients feel at ease.

I accept referrals for all types of root canal treatment, including more complex cases and teeth that have been previously treated but need further care, and I’m a member of the British Endodontic Society.

Associate Dentist

Lindsey Dixon

Qualifications: BDS (Hons)
GDC: 258994

I graduated with Honours from The University of Manchester in 2015 and have since gained experience in a wide range of dental environments, including community dental services, hospitals, and both NHS and private practices.

My role as a dental officer in community dental services gave me the opportunity to treat patients with complex medical and dental needs, as well as those experiencing dental anxiety and phobias. I also provided specialised care for children outside of a standard dental setting, which further deepened my commitment to patient-centered care and shaped my approach to dentistry.

Now working in private practice, I enjoy treating both adults and children, ensuring every visit is as comfortable and positive as possible. I have a special interest in children’s dentistry, focusing on creating a fun and stress-free experience for young patients. Whether they’re excited or anxious, I use various techniques to help them feel safe and confident. My goal is to ensure successful treatment while building their confidence so they look forward to returning in the future.

I’m also passionate about cosmetic dentistry and am a certified Invisalign provider, helping patients achieve their ideal smiles with confidence.

Outside of dentistry, I’m an avid outdoor enthusiast who loves hiking, cycling, and staying active. I’m also passionate about travel and enjoy singing in a choir and playing the violin whenever I can.
