Dr. Doug is honestly THE BEST dentist I've ever had! I got in an accident and got a couple of my front teeth broken and/or knocked out and Dr. Doug went above and beyond to give me my smile back within a year. They look better than they did before! He's even fixed problems left or created by the work of my previous dentist.

Started seeing Dr. Kosek 2 years ago. Such a great dentist. I enjoy his and his dental hygienists work so much i even got my mom and dad to go to him. Would highly recommend him to anyone! I also must admit that I love that went to Purdue University like i did! Love a fellow boilermaker!

I have never really been much of a fan of the dentist, but Doug and his crew are fantastic. I look forward to seeing them for cleanings and ortho care. They are by far the very best dental team I’ve ever had. Nice, they care, they remember things about their patients, they’re gentle. All amazing things.

Have had a vast amount of dental work throughout my life visiting multiple Dentists. Nothing compares to Dr Kosek and his team. The entire staff is incredibly warm, friendly, and professional. I am very happy and confident in their practice and would strongly recommend them to anyone!

Jonathan N.

I have been going to this dentistry for 15+ years! Dr. Kosek is beyond exceptional in all aspects, ranging from his ability to calm any child down to truly aid anyone in a dental need! He only hires the kindest hygienists and coworkers. I was lucky enough to be treated by his newest young doctor, and his charismatic attitude matched Dr. Kosek’s!

Caroline B.

I love the entire staff at Dr. Kosek’s office, they are so friendly and accommodating. I’ve always felt more like a friend there than a client. He’s the first dentist that I not needed Nitrous gas with. He’s so extremely gentle that I’m fine without it.
