Hands down the most beautiful dental office in the area. It’s upscale, spotless, and conveniently located. You can tell they put a lot of thought into the patient experience and the aesthetic of the office. 10/10 for professionalism and atmosphere!

What an amazing experience. From the beautiful ambiance, welcoming staff, all the way to the expert dental care, Dr. Kooper at 405 is amazing. I have sensitive teeth and hate going to the dentist. This appointment was easy, painless and we have a great plan for my bite and smile. Definitely worth every star.

Tell your dentist to go fly a kite. Dr Kooper is the the best in the business! When I showed up I had some serious issues. Having tried many other places that never felt like the right place for me, Dr. Kooper’s office is the BOMB!!!!! It’s like family. Just stop by and introduce yourself, you’ll see what I mean. Thanks Dr. Kooper for getting me my smile back!

Great place to have your dental work done. The staff is friendly and attentive to your needs, all with a smile on their face. Everyone appears to know their job and excel at their performance. The new building is done in an open, inviting manner with a nice modern design, but don’t let the new building fool you, the staff are not new at what they do. Highly recommend

Really nice atmosphere, receptionist was really sweet and the doctor and his assistant was amazing. I will definitely be going back and I will refer my family and friends to them as well. I didn’t have the best experience at my dentist before this one and walking in this place makes you feel at ease!

I had my wisdom teeth removed by Dr. Kooper and I couldn’t be happier with the experience. From the initial consultation to the post-op follow-up, everything was handled with professionalism, care, and compassion. If you’re looking for a skilled, kind, and trustworthy dentist for anything dentistry related, I highly recommend Dr. Kooper and his team. They turned what I thought would be a stressful experience into a very positive one.

Kinzie truly goes above and beyond for her patients. She makes you feel comfortable, informed, and genuinely cared for. She’s knowledgeable, and attentive, which makes every appointment run smoothly. She has such a calming presence and a positive attitude. Her professionalism, work ethic, and compassion truly set her apart. Any office is lucky to have her, and I can’t recommend her highly enough.
