Meet The Team

Aron Marcus BDS

Team Aron Marcus BDS

Dr Aron Marcus graduated from the prestigious Kings College London Dental School in 1985. After qualifying, he spent his first year in hospital dentistry where he obtained a broad range of experience before moving to general practice.  In his early years as an associate dentist, Dr Marcus soon became extremely popular with his patients owing to his caring and gentle approach and his commitment to quality. He also developed a keen interest in all aspects of restorative dentistry, in particular crown and bridgework.
In 1993, Dr Marcus set up his own practice in North London. Recognising the need for extremely nervous patients to have access to dentistry, he became proficient in IV sedation and was soon well known in the local community for carrying out this treatment in a particularly caring manner. At the same time, he pursued his interest in implant dentistry, attending a year course in this speciality and later at the Bicon Dental Implant Institute in the USA. He continues to practice implant dentistry and has, to date, successfully completed many cases with excellent results and feedback from his patients.
He also developed an interest in Endodontics (Root Canal Treatment) and in 2004 completed the Eastman's Certificate in Endodontics.
In 2002, Dr Marcus moved to Whetstone, taking over a long established family practice and continues to provide the same quality of service to his growing list of patients along with his two associates and two hygienists.
Throughout his career, Dr Marcus has continued to pursue postgraduate education and is regularly updating his knowledge in all areas. He is a member of various professional bodies including the BDA and the Association of Dental Implantologists. He is also past chairman and trustee of the London Chapter of Alpha Omega, an international Dental charity.

Dr Marcus is married with three children but still manages to remain relatively sane.
