Dr Liam O’Sullivan qualified from University College Cork, (NUI) in 1981 and practiced in the UK in general practice for a number of years. On returning to Ireland, he set up a private practice in 1990, offering routine, advanced restorative, cosmetic dentistry and orthodontics. This included the taking of continuing professional education courses in all of these areas including post-graduate studies in Trinity College Dublin.

The greatest problem facing the general dentist is the cosmetic/aesthetic replacement of lost or very damaged teeth. Therefore, a fascination with the possibilities offered in the use of dental implants to permanently replace missing teeth took hold in 2004. “This emerging area of dentistry can provide solutions and aesthetic results that could only be dreamed of when I first qualified.” There followed a series of courses in Europe, culminating in studies for the Diploma in Implant Dentistry, at the Royal College of Surgeons of England in London. Liam has been working with Smiles Dental at Waterloo Road, since 2011.

Dr Dan Gruenfeld graduated from the University of Tuebingen in Germany in 2006 with first class honours.

In his quest to provide outstanding treatment for his patients, Dan incorporates the most modern techniques and digital procedures such as guided implant surgery and minimal invasive surgical protocols to ensure a least traumatic patient journey to their perfect smile.

From a single tooth restoration to full mouth rehabilitations, Dan offers a large spectrum of contemporary treatment options. He specially enjoys solving challenging cases involving a multidisciplinary approach. Dan is an active member of the ‘Irish Association of Aesthetic Dentistry’ and a regular attendee of national and international conferences on Periodontology and Implant Dentistry.
