the team


simplyendo was set up by Mike Horrocks in 1998 with a very simple aim,

"To improve the quality of endodontic care in the UK" 

Initially concentrating on providing endodontic referral services, simplyendo then launched their education programmes in 2003, and they have proved to be very popular with dentists who wish to advance their knowledge and skills in this field. The programmes have now been accredited to Masters degree level.

Please read on for details of our highly experienced endodontic team, starting with our clinical and teaching team.

Mark enjoys doing and teaching endodontics to a high standard. As secretary of the British Endodontic Society, he is involved with the politics of endodontics at a national level. When not stressing about endodontics, he is never happier than when running competitively or cycling on his Brompton.

Dr. Steve Cowling BDS MSc


I am the Endodontic Officer for Betsi Cadwaladr University Health Board in North Wales.  I accept endodontic referrals from community dentists and also the Maelor hospital in Wrexham and Glan Clwyd Hospital, Rhyl.  I am also a postgraduate tutor in endodontics for Cardiff University. I gained my Masters Degree in Endodontology from the University of Chester in 2011.  Not bad for someone who used to hate endo! My conversion and subsequent love of endodontics was inspired by simplyendo and I am proud to be part of what I consider to be a great teaching team.  My other main interest is in antiques and I run a small company, Kinton Grange Antiques, specializing in Victorian Tunbridge Ware.  Any spare time I have is spent reading, cooking, shooting and wandering the local countryside with my black Labrador, Mason.

Dr. David Baker BDS MSc


I qualified with Honours in 2004 from Liverpool University and went on to complete General Professional Training, with vocational training in Liverpool, followed by a Senior House officer role at Liverpool Dental Hospital. I completed the MJDF RCS (Eng) in 2011 and completed my MSc in Endodontolgy from UCLAN in 2013. My dissertation compared various obturation techniques.
In 2013 I joined Hob Hey Dental Centre, a Private Practice in Culcheth, Warrington, where I accept local endodontic referrals.
In 2014 I became a certified Dentsply Maillefer trainer having undertaken training in Maillefer, Switzerland, and I am massively excited to have recently joined simplyendo.
Away from Dentistry I am married to Emma (another Dentist!) and we have 2 daughters- Heidi (4) and Daisy (1). I love cars, football and boxing…..I have no free time!
