Dr. James Gregory Koller

This a great dental practice! I just had my first crown done by Dr Koller. No molds made and sent out and then waiting and having a second appointment. Porcelain crown made right in the office. Seems like state of the art equipment and imaging for this process. A little more than 2 hours and done! Other than tiny pinch of needle for novacaine, 100% pain free! I would definitely recommend. There’s also Dr Leah and another Dentist, Dr Englund I think? In N St Paul by the snowman.

I started going to Dr. Koller after my dentist passed away and have had wonderful service. The staff is great also. I have referred a few people to him and they are very satisfied as well. I will continue to go to him for all my dentistry needs and keep referring people I know to at least confer with him before they make a big decision on their dental needs.

Great ppl I feel relaxed

Jake is not just a fine gentleman, but an outstanding dentist. He cares for his patients just like he cares for his friends.

Best Dental Practice I’ve ever been to. I am in health care and HATE going to the dentist, have sooooooo many issues with my teeth— not my best feature— believe me... and I have postponed going to the dentist for too long. It was nice to be treated with respect by a very intelligent and thorough dentist and given all options, not just the ones that would “yield them more money.” My dentist was Dr. McComas who was very thorough, respectful and genuinely kind. She did confer with Dr. Koller regarding my dental challenges and he reviewed my x-rays and they mutually discussed my options. I am like millions of people in this world that do NOT see the dentist because we wait so long, too long, and would do absolutely anything to avoid having someone look at our teeth. I highly recommend this Practice. They are a little gem sitting in quaint downtown North St. Paul! Best Dental Practice I’ve ever been to.

I've always disliked dentists. But I can honestly say I go ever 6 months for cleaning and if I have any problems, I call and make an appointment right way. The whole staff are great,nice and understanding. Dr. Killer is very good also!

We love Dr. Koller and his staff. We have always received quality care and they have always been there for us in emergencies. Usually by providing care but once my son had an abscess on the weekend while Dr. Koller was out of town. He returned my sons call and referred him to someone that could help.

We started with Dr. Koller and his team in the last year and were so pleased with the care and service received. The Front Desk staff, the Dental Hygienists, and Dr. Koller and Dr. McComas are so professional. Their service is amazing, and the care devoted to clients is wonderful. We are very impressed with the degree of service and attention to detail. We would highly recommend this clinic and staff to others. I have been in healthcare for many years and applaud their commitment to quality and cost effective care.

Fantastic, old school dentist

Friendly, professional staff. Make you feel comfortable.

Amazing dentist and hygienists! I was anxious to go to a dentist because of past experiences, but Tony put me at ease. She made sure I was as comfortable as possible! She was just wonderful! When Dr. Koller came in he also made sure I was comfortable and shared his concerns, but made sure not to blame or shame me. He created multiple options for me to choose from and made sure to work around my hectic schedule. I can't imagine going anywhere else now! Amazing dentist and hygienists!

Intimate little clinic. The staff are fantastic and accommodating. Have had only positive experiences so far. Dental work was excellent (no mistakes and genuine concern for my comfort). Thanks so much, everyone!

BEWARE! James Koller dds. broke my back tooth when replacing a filling. My mouth was so numb I couldn't feel how hard he was drilling. After he broke the tooth he said, "well do you want me to take it out"? He could not complete the task and left the root of my tooth exposed. He acted like he could care less. I had to go to a professional and spend more money to have the root of my broken tooth taken out, then kept billing me for his mistake! My teeth have been shifting every sense. If he's not having a good day beware!!!, you could lose a tooth. Funny thing is, I had gone to him for years... BEWARE! James Koller dds. broke my back tooth when replacing a filling.
