O'Kane & Monssen
Leaving the dentist office with a healthier, happier smile is why families trust O'Kane & Monssen Family Dentistry. From little tykes with first-time teeth to grandmas and grandpas with teeth that have enjoyed life, we've been putting happy smiles on faces in the St. Paul Highland Park neighborhood for more than 60 years.

I had not been to see a dentist in over 10 years! So it's an understatement to say that I was nervous. But I could not have asked for a greater experience. Everyone was super nice, helpful, and knowledgeable. They all took the time to explain things to me and even to get to know me, though small talk is nearly impossible when someone is working on your teeth.

Had my cleaning done today. Geneieve did an awesome job! She was very gentle but firm because I can feel things come off. Haven’t felt this clean in a while!

Dr. Monssen is great! He is conscientious and does not do more than is necessary to take care of the problem. He is friendly and truly cares about his patients. The dental hygienists and front office staff are competent and a lot of fun.

We have always gotten great care with Dr. Monssen and team. But last week they were able to see us as a last minute request to help my daughter with her braces. They are so nice to us all the time and they are an excellent team. I highly recommend them.

Went in for invisalign consultation. Had to schedule a month in advance for a follow up and was forced to reschedule just a few days before my appointment. I was quoted 6-9mo for the plan, but when I asked not to have the invisalign attachments (bumps) on my teeth and was told that it would take 2 years. I was later asked to pay $2,700 up front for the plan. Given that the estimated time for use was 2 years, it seems ridiculous that I'd have to pay a majority of the cost up front. It's clear that they are trying to ensure they get as much money as possible just in case I decide to stop the plan

I see Dr. Howley, as do my kids. He is friendly and knowledgeable. He's good for cleaning, filling cavities, and he got me a retainer so I don't grind my teeth. 5/5 would recommend.

The Doctors and Hygienists here are top notch. If you ever dreaded going to the dentist for your checkups or procedures, this is definity the place to go. Everyone here cares personally about accommodating your potential discomforts. They will even teach you how to get into the crevices between your teeth at home if needed. Or suggest ways of improving your daily brushing routines based on plaque patterns they find.

Dr. Howley and the entire O'Kane & Monssen staff have been incredible. From the first time I called to make an appointment, Marilee made me feel right at home, almost like I was joining a family. Dr. Howley has been incredibly professional and also educational in the services I have received. Highly recommend this practice.
