Our tutors all have an MSc in Endodontology from various teaching institutes in the North West. They each bring a wealth of knowledge and experience when it comes to diagnosing, planning, and treating complex endodontic cases. They’re also highly experienced at mentoring students with their postgraduate studies.

Our clinical team are all qualified dental nurses, some of whom have over 20 years’ experience as an endodontic nurse. We assign two members of the clinical team to each hands-on room, to assist the tutor and the delegates with the practical sessions in the afternoons. They know everything there is to know about endodontics.

Our admin team consist of ex sales personnel from some of the largest endodontic companies in the world. We also have colleagues who are experts when it comes to writing academically and anything essay related.

I joined the simplyendo team in summer of 2020. My role here is multifaceted and it’s great as I get to do lots of things to help out the team and students! I help out in the office with administration and also with our marketing and social media. You will often see me walking around the building with a camera or my phone!

I love animals so I always love spending time with my dog Jasper and sometimes bring him into work, as after all he is a working dog!

I have worked with simplyendo® since 2018, and you will usually see me glued to a computer screen in Mike’s office.

I make sure the Assessment & Monitoring process runs smoothly, I develop and improve our business processes and related documentation, I manage Fire Safety, and I pick up any other tasks I can squeeze in to reduce Mike’s workload so he can spend more time doing the things he enjoys most!

I absolutely love wild camping and grab every opportunity I can to escape to peaceful places and soak up nature’s energy in the middle of nowhere, leaving nothing but footprints! I also grab any opportunity to get out dancing, and to make special memories with my family & friends.

I am a keen amateur photographer.

The programmes are offered at several locations in the UK. These programmes have now been accredited to full Masters degree level and I spend about 50% of my time teaching and sharing my experiences and knowledge of endodontics with my professional colleagues.

Dr Steve Cowling
Dr Steve CowlingBDS (Lond) MSc
I used to hate root canal treatment and when a colleague asked me to accompany him on a course I said an emphatic no. However, he pleaded with me because he did not want to attend on his own. The course was simplyendo’s 10 day course but I was so not into root canal treatment I did not bother turning up for the first day. To my surprise, on the fourth day, I found myself enjoying myself and the rest is history. I was a member of the very first cohort to take the Masters degree and I gained a Merit in 2011. I went on to become the Senior Dental Officer responsible for Endodontics at Betsi Cadwaladr University Health Board in North Wales taking referrals from the Community Dental Service and various hospitals in the area. I also ran practical teaching days for dentists in the area.

I no longer actively teach at Formby but am still very involved with simplyendo and I thoroughly enjoy working in the background for delegates as they take their first steps into the world of endodontics.

In my spare time I like walking the countryside with by black Labrador, Hudson. I have a love hate relationship with gardening but love cooking, especially Asian food. The best time of the day for me is the evening when I relax with a good book.
