Koski, Depaul Dental Group has been taking care of our families dental needs for over 50 years and we couldn’t be more pleased with their experience, knowledge and professionalism.  For those reading this review who have been putting off going to see a dentist because of your anxiety, I suggest that you give them a try and see for yourself how stress free “seeing the dentist” can be.

I have been coming here since I was a kid (30 years!) and everyone is great. Personable and caring, they make the whole experience positive. I’ve never dreaded going to the dentist, and I’m sure it’s because I’ve always come here. I highly recommend going to Koski DePaul; you will enjoy visiting the dentist!

Dr. Koski and all of his staff go out of their way to make sure you feel comfortable and that your concerns and needs are addressed. They are efficient and friendly and really care about their patients and needs. They are up to date with their education and have the latest procedures available to you. Would definitely highly recommend.

I have been a patient of Dr. Diane DePaul for a very long time. She has performed countless repairs on my teeth since I was a child in elementary school and I can confidently state that her procedures are painless. As a second grader i ran face first into a basketball pole at recess and broke my nose, broke my front teeth, and split my upper lip. Dr. Diane patched me up and made the entire ordeal (which was pretty traumatizing for an 8-year old) as painless as possible. Dr. Diane and her partners manage a safe, efficient, clean, and professional office where all employees are friendly and helpful. Upon arrival for a cleaning or follow up I have never waited longer than 10 minutes in the waiting room. Nada is the hygienist I see regularly and she is incredibly thorough and always friendly. A dentist visit is something universally avoided by most but Dr. DePaul and staff go above and beyond to make the experience as stress-free and painless as possible. I hope to be a patient of hers for a long time.

I flew in from Atlanta to get my teeth fixed by Doctor Diane. It was so worth the travel. I had a crown plus a front chipped tooth fixed along with blended veneers in the front and complete xrays and cleaning. Wow i was amazed at all the high tech equipment and everything was done in one session. Thank you doctor.

I went in for my cleaning yesterday and everyone was getting used to new rules and procedures related to COVID-19. I felt very safe with the practices they were implementing and they explained those changes and practices all along the way. As usual, everyone was wonderful and I am grateful to them for all they did to keep us all safe while having a good appointment.

I used to hate going to the dentist but after going to see Dr Koski and his staff I look forward to it. I’ve had my teeth whitened and did Invisaline with them and have never been happier with my smile. I highly recommend them!

Dr. Koski and his team have created a dental experience that is professional, supportive and sensitive to the needs of his patients. I used to have extreme anxiety about dental procedures. However, I am now able to schedule appointments with ease because I know the staff and atmosphere of the office puts patients first. I am grateful that a friend recommended this wonderful office.

I am a person who is terrified of dental work. This practice performs pain-free, stress-free dentistry. I couldn’t believe how easy they made it and how comfortable I was in the chair. Dr. Koski and staff are personable, calming and efficient. The quality of their work is top notc

I have been going to Koski DePaul Dental Group since I was a teen and with good reason. Consistant, exceptional service no matter what. Whether it’s a routine cleaning, or full mouth reconstruction, this practice does it all. Dr. Koski, Dr. DePaul and their entire team go above and beyond to make you feel welcomed and comfortable. Keep doing what you’re doing. Your patients appreciate it!

Laura S. from Cleveland, OH (Source: Yelp)


Dr. Koski has been our dentist for many years. Yesterday I had a crown replaced and it looks beautiful! No need to return for another appointment for the NEW crown…….he made it right there in the office!! Dr. Koski is very detail oriented, always does what is best for the patient and my teeth look great. His staff is efficient, professional and kind. Thank you all for taking such good care of me and my husband.

I am still a patient and want to say that four (4) years after my first review, I can still rave about Dr. DePaul and Dr. Koski, as well as all of their staff. Everyone is truly AMAZING!!!!! The dental hygienists do an excellent job with their cleanings (every single one I have been to has been outstanding!!). The dentists and staff are incredibly thorough, patient, and kind. They know what they are doing and they do an excellent job. They keep very detailed notes and keep a watchful eye on any concerns or issues. I cannot sing their praises enough!!!

I suffer from extreme dental anxiety. I had my first appointment today with dr Diane and she took the time to understand me and make me feel so comfortable. The whole staff made me feel that way. 5 minutes into the appointment I was completely relaxed and didn’t want to run out of the building! Thank you so much to all of you!

I’ve been with this practice for 20 years and received extraordinary care throughout. Visiting yesterday and for the first time during the Covid pandemic, I am absolutely impressed with the protocols and extent to which they went to make their service safe for all of us. They just seemed to think of everything from sanitizing the pen I used to changing the polishing procedure, to hand sanitizing before leaving the office, and much more. I truly appreciated their most thoughtful approach and planning.

I was very hesitant when called to reschedule my cleaning during this pandemic. I have to say everything was handled so professionally with every safety precautions in place as soon as I arrived, actually before I even stepped into the door! I received a phone call the day before, and was given details as to how everything would go. I was informed to call when I arrived. Once entering, I answered a few questions about my health and how I was feeling, my temperature was taken, then within minutes I was taken to a room and a very thorough examination took place. My anxiety was put to ease as Megan, my hygienist did my cleaning. The calmness in her voice allowed me to relax without worry. Thanks Megan!!! Thanks to the entire Koski DePaul Dental Group for going over and beyond to keeping us save during these trying times, and allowing us to feel at ease during our cleanings and dental needs!

Dr. Koski and the entire staff are the best in the business!  I don’t feel like “just another patient” when I am in their office!!  I have had implants, cavities, veneers, root canals, and other procedures (yes, I eat a lot of sugar) and I highly recommend him for all of your needs!

Laura G. from Willoughby, OH (Source: Yelp)


Dr. Koski and his staff are the best in the business!!  I recently switched from another dentist and just wish I would have done so sooner.  Dr. Koski is very thorough and is a perfectionist.  He doesn’t put pressure on you to have a procedure done, and he will give you his honest opinion.  So far, he has done fillings in some very bad teeth and it was pain free. He has also bonded my front teeth and my smile is beautiful, no more crooked teeth!!  He is prompt and takes his time with you.  I would DEFINITELY recommend him.

Koski & DePaul Dental Group has been taking care of my family for the past 20 years. Besides being extremely competent and knowledgeable, we have found everyone in the office to treat patients and each other with respect. The office is very clean and well managed. I would say that even pre-pandemic, the safety and cleanliness standards in the office exceed minimum standards to be sure. There is definitely a calm and peaceful atmosphere at this office- which makes the whole appointment experience very pleasant.

Everyone at Koski DePaul Dental Group goes above and beyond to make you feel comfortable. Dr David Koski is extremely talented, and makes you feel relaxed about having the work done. I have always had a fear of going to the dentist, but the staff at Koski DePaul, from the dentist to the hygienist to the receptionist, ensures you have the best experience possible. If you’re looking for a new dentist, look no further!
