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 the first point of contact at the beginning of the simplyendo journey, the 10 day programme. I deal with all direct enquiries to simplyendo. I provide information, support, registration and create pathways to the MSc for students. I develop course timetables, programme registration forms and deal with student accounts, course evaluation and feedback. I love to walk with my 2 dogs and listen to any kind of music as I go. I am a keen amateur photographer.

Prior to working at simplyendo®, I worked at Dentsply Sirona for 5 years as a sales manager for the preventive, restorative and endodontic division. I supported simplyendo® courses at the education centre in Formby and at various teaching hospitals in the North West. I was delighted when Michael offered me the opportunity to become part of the simplyendo team in January 2021.

My role is technical support, but I also help out with various projects, incoming enquiries, and supporting the tutors as / when needed. I have a degree in Business Management from the Open University and at some point, I would like to do a masters.

Outside of work I’m interested in F1 / cars / boats / aeroplanes / horology / music / cooking / walking.

I have worked with Mike Horrocks and the team at simplyendo since 2010. My previous role was as a qualified Dental Nurse and Practice Manager, however I now work behind the scenes at simplyendo.

I currently work in a Quality role, producing simplyendo documentation that helps us to continually improve our service and to ensure a consistent approach. I also manage our continuous improvement plan and COSHH. I work from home so you may not see me on your visits to Formby.

Away from work I love to read and socialise with friends (when I have time… as I have 2 wonderful children who take up most of my time!)

I completed my MSc in Endodontology with simplyendo® / The University of Chester in 2014, gaining a distinction grade overall. I enjoy teaching endodontics, I joined the simplyendo® teaching team in 2015.
I’ve been taking referrals for endodontic treatment since 2011 and limited my clinical practice to endodontics in 2016. I currently accept endodontic referrals (non-surgical and surgical) at Witton Street Dental Practice, Northwich and Oracle Dental Clinic, Shrewsbury. Prior to this I previously worked for 5 years in the simplyendo® endodontic referral clinic in Altrincham.

I was born and bred on the Fylde coast, just 20 miles from the simplyEndo® teaching centre in Formby. After qualifying from Liverpool Dental Hospital in 2000, I worked on the Wirral for several years in general practice. It was around this time that I became interested in endodontics, devoting much of the CPD time to the subject. I passed the MSc in endodontics in 2017 through simplyendo® and was delighted to be asked to pass on my experience by becoming a tutor. I now work in Teesside as Clinical Director for the Riverdale group, where I split my time between general practice and endodontic referral practice. Outside endodontics, my two children occupy most of my time and I also enjoy fell walking, cooking and music.

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.
