Mount Merrion Medical Clinic

The Clinic was established in 1989 by Dr Noreen O’Hanrahan and relocated to its current premises in 2006.  

We now have three doctors, Dr Noreen O’Hanrahan, Dr Gillian McLaughlin and Dr Thomas O’Byrne and our practice nurse Vanessa Mulcahy, supported by a dedicated team of secretaries, Ann Keegan and Sinéad Doheny, and practice manager Brendan Geraghty.
