I am not one who likes to go to the dentist but my experience at Northern Horizons Dental and with Dr. Kong was stress free. The whole staff was... friendly and made me comfortable throughout my appointment and Dr. Kong explained everything he was doing and asked if I was okay during my procedure. Highly recommend Northern Horizons for all your dental needsread more

Dr. Sullivan prevented me from leaving and finding another dentist today! I did not appreciate having to wait close to an hour when I showed up on... time to my appointment but he did not rush me out. He explained in detail my results and assured he and I were on the same page. I will give it another try before I decide to continue or not.read more

I had an emergency and was seen within a few hours of calling. As a new patient they were accommodating, helpful, honest and professional. The place... is modern, clean and sterile and I felt safe as per Covid protocols they have in place. From my initial interaction with Jessica at reception, to the dental tech with her kindness and hospitality and Dr. Sullivan with his honest and transparent advice and actually solving my emergency issue with the extraction. I highly recommend this place! Most important a plan was in place and I’m feeling almost 100 % better then from this morning. Thank you for the wonderful service today.read more

Years ago I had a dental mishap and scrambled to find someone (anyone) open to take me. Glad I got a chance to meet my dentist (Dr. Sullivan) at... Northern Horizon because it was an eye opening experience. I don't have fear of dentist, but, I have needed dental work quite often and always just tolerated whatever result I got. Turns out there's dentists and artists. Dr. Sullivan is an artist. He also happens to be charming, and dentist can take all the charm they can get.The rest of the staff at this location is similarly personable and I've been a happily committed client ever since.read more

Moving from Toronto to Innisfil I knew I would have to switch dental offices eventually to make life similar for our family. I asked on a Facebook... chat group which dental office would people from town recommend and Northern Horizon Dental kept coming up. My friend also highly recommended it. I made the call and booked my family in one by one. We are happy that we found a great team to look after our teeth. Thank you!read more

Consistent Experience Every Time!My wife and I have been coming to Northern Horizon Dental in Alcona since 2019 and the level of customer service... from the time you check in, to the moment you book your next appointment is second to none! Denise, Pam and others who have been at the front desk are very accommodating with billing arrangements, appointment changes and reminders. Also, the quality of oral care I've received from Amanda and more recently Treza and Tarlan have been superb! The environment is safe with all the Covid Protocols they have in place! Keep up the good work everyone!read more
