WHO ARE WE?
We are a husband and wife team with over 48 years of combined experience. We graduated from the Cork Dental School in 2001 and have been practising dentistry ever since. We live in Co. Sligo with our three young children. Gavin likes to keep fit and has a passion for all sports, especially rugby and tennis. He enjoys a spot of fishing, getting into the sea, and the peace of nature. Fionnuala enjoys painting, cookery, hiking, embroidery and music. She has a keen interest in art and antiques and loves to spend quiet time in nature. We both cherish spending quality time with our family in the outdoors.
WHY WE DO WHAT WE DO
In 2025, we established Deasy Dental and Orthodontic Care with the mission of delivering the highest standard of dental care in a relaxing and calm environment, using the latest in modern technology. We are committed to fostering honesty and transparency in all our interactions and hope that everybody we encounter on our journey leaves feeling better for having met us. It is a priority for us to really take care of our patients, and we look forward to providing dental care to the people of Ballisodare and the surrounding hinterland.
