What our patients say

There’s a reason why our Google Reviews gives us a 5-star rating.

Encountering a medical challenge can be a frightening and distressing experience. I took my mum to The Newry Clinic where all her worries (and mine) were dealt with professionally, calmly and sensitively. The appointment system was efficient and immediate, the welcome from all staff was reassuring and personalised, and the medical consultant had expertise and patient care in spades. Due to the current health care context in Ireland we found ourselves pursuing the private route for the first time, it was a pleasant and reassuring experience at The Newry Clinic.

Had my dad at the clinic recently for Microsuction, fantastic service from Nurse McGarry and all the staff in the clinic. He felt so comfortable and enjoyed his experience, leaving the clinic with a smile on his face!

Martina McCartan, Newcastle

I attended an appointment with Dr. Glackin. my appointment was very professional and reassuring. The staff at the clinic were very friendly and helpful. Would definitely recommend!!

Odhrann McAllister, Dublin

I went to the gynaecologist in this clinic after attending one locally with an ongoing problem for over 10 years. In one single visit I was told the problem and given a prescription there and then. I'm forever thankful to the doctor as I was being treated for the wrong thing for years.

Orla Callan, Belfast

I dont usually write reviews, but for Mr. David McCaul, I owe you one! I have had 2 encounters with Mr McCaul now, once last year to fix a perforated ear drum and a few weeks back to have a procedure on my throat. He has helped me in many ways, fixing my eardrum and giving me my hearing back to 100% volume. if anyone has ENT issues, and need a diagnosis or even just a bit of reassurance, This is one Gentleman that I would give the highest recommendation for. Thanks Again to Newry private Clinic and Mr McCaul.
