I recently had a root canal performed and it could not have been a better experience. Dr. Lansdell was thorough in his explanation of the work to be done and I had absolute confidence going in that after the procedure I would be pain free. Overall it was a great experience and I cant recommend Dr. Lansdell and Gordon street dental enough, Im very happy I made the switch over to Gordon street dental and will be recommending my friends and family as well.

This dentist is great! I have been to 3 different dentists in Guelph and this dentist did by far the best freezing job, I felt absolutely nothing when they were freezing. The staff is very friendly. Highly recommend this dentist.

Proactive, experienced, knowledgeable dentist. Explains procedures thoroughly so that you understand why they are being done. Educates the patient so that they can make an informed decision. Two thumbs up!

Consistently thorough, thoughtful, and professional service with a dash of humour to keep things fun. Cleanings are top notch and every time I go there seems to be a new tip that inspires. Dr Lansdell always gives lots of info when theres an issue and the work is solid. Great team across the board. Maybe worth noting I have been with Gordon St Dental for well over two decades and am an actual patient ;) happy to recommend.
