Mark Bishop became a dentist (BDS 1973) at Bristol University. He has worked in clinical dentistry and in basic science related to dentistry. Although he has done some general practice work, more recently he has practised endodontics exclusively.

Mark has also completed a training (MSc) in endodontics at King's College (Guy's Dental School) in London. Prior to setting up this referral practice in Guildford he worked as an endodontist in practices in London, Kent, Berkshire and Hampshire.

Mark has taught anatomy to dental students in Great Britain and North America. His research included a PhD and concentrated on the nerve supply, blood supply and formative cells (odontoblasts) of the dental pulp. The pulp is the tissue that becomes damaged or infected and leads to the need for endodontic or root canal treatment.

He established the referral practice in Endodontics in Guildford in 2002.
