So when I came down to my mom's I called and not only did they see my THAT day they were able to get me in the day after to get my tooth fixed!!!The dentist took the time he did not have to take to go over my x-rays and explain very well what the problem was !Amazing dentist, amazing people !!! I'd honestly take the 4 hours trip to them anyday !!Thank you so much for helping me out ! This was the break I needed .I could kiss all of you !read more

This is by far the best group of dentists, dental assistants and even the the best receptionists!!They care about patients to the fullest., I made a... request for an emergency appointment at 3am on their website, and I was in by 1030am. This happened March 31st 2023, Dr Hanna was quick to examine the tooth and gave me 2 options Root Canal or Extraction and gave me the info required to make a decision including the price break downI will NEVER go anywhere else, I became a Patient In 2022 after I broke a molar and even then Dr Kong was kind and very informative as well.I HIGHLY RECOMMEND!! 11/10read more

I like Nothern Horizon Dental Barrie because its the only dentist place I have ever gone to. I am upset because when I was younger there were toys... here. I loved playing with them and that's the only reason I liked it here. But now I come for the treasure box. Which got old fast. I hope you guys will bring back the toys. Please do. 😫🙏🙏💓😜read more

I saw Dr Sullivan and my experience was very 👍 good.He genuinely cares for his patients, explains what is happening, maintains proper... evidence of each tooth he looks at (surpirisingly not all dentists do). He has quality dental assistants/hygenists and overall a caring, knowledgeable and thorough dentist. No issues with his care I like how he has a conservative dental approach.read more

Hadn't been to a dentist in a long time. Then after moving to Barrie I went here. From the get go,the front desk super nice. Then onto Christina... who treated me with upmost respect while taking all my different pictures that were needed and was super nice. Then I had Dr Seok and she went out of her way to explain everything she was doing and answered a ton of questions and again was super friendly and professional. Then finally I had Chelsea who did a cleaning on me. Absolute sweetheart always checking if I was conformable and did a great job. So far from my 1st visit this is so far the best most well equiped and professional dental establishment I've ever been too. Highly recommend!!read more

I went here today for a checkup for me and my toddler. The experience was the best we had from the phone conversation to the goodbyes. The entire... staff made sure the whole process was easy and quick. My toddler was the first one to have his teeth checked. Chelsea explained everything to him Ina fun and easy to understand way and had him try out all the safe tools. By the time she was done with the demonstration he was excited to have her look at his teeth. It went flawless! When it was my turn, they had a treasure chest for him and Gayle at reception kept his so entertained he didn't want to leave. Dr. Hannah was thorough and professional and made is both feel comfortable. Highly recommend!read more

What started as a great practice turned around in the last 2 -3 years. All they want is money. I complained about a problem with a tooth and they... did 3 different teeth before getting to the now completely damaged tooth. New dentist every time has to say something with the latest one giving both me and my wife the same excuse of why a filling came out claiming it’s not they’re fault. Find any other dentist around and you’ll do better. There is just to much to complain about.read more

I didn't have a dentist or insurance when I found this place through a friend of my moms, so I figured they were worth a try. They fixed a cavity on... the spot when I went in thinking I had a hole in a tooth and needed it pulled, and worked with me about paymentsNow that my insurance has kicked in, today I had three of my four remaining wisdom teeth out and it went wonderfully. I was very nervous as I don't love the dentist but they're all so friendly and accommodating. I will 100% be back in the future for the rest of my dental needs. Wonderful people.read more

So unprofessional. The assistant with red hair has a very loud dirty mouth and can be heard cussing and using inappropriate language from other... rooms. The lady Anna at reception is extremely rude and does not even smile or use a friendly tone. And the lady dentist seems like she has no clue what she’s doing and asks even the assistants what to do at times. The only good thing about this place is their hygienists and Dr. Sullivan, as they have always been great and friendly. Save your money and go somewhere elseread more

He’s so patient and gentle it makes the visit seem like a cakewalk !! Any other dentist would of been awful but like I said Dr. Sullivan is such a great dentist the whole appointment is pain free and just a joy to experience! He brings the name Dentist to a whole new level!! Thanks Dr. Dan your the BEST!! Mike Creamerread more

Hello.I have been coming to your clinic for quite some time now and am very happy with the treatment and services provided . Thank you .Just wanted... to address a concern, that I have from my last teeth cleaning appointment.I felt a bit rushed during my treatment, the time spent does not relate well from when I was taken in for my appointment at 6:12pm and was out by 6:40pm and my receipt signed out by 6:50pm. I am pretty sure that the hygienist( that treated me) is competent and is a great hygienist, but, I just wanted to bring it into your notice. Because I never had cleaning that fast before.I am still going to be coming to your wonderful clinic in future.Thank you for your time and consideration.read more
