Testimonials From Our Patients

See what patients are saying about us......

I've been seeing both Dr. Nelson and Dr. Bacos for over 20 years.  Their level of care and commitment to patients' needs is unmatched.  Dr. Nelson did my braces  several years ago and I couldn't be happier with the results.  I had always been self conscious about my smile, but now I LOVE showing it off!   It's so refreshing to go to a healthcare provider that actually takes the time to listen to your concerns and makes sure you're comfortable along the way.  Their personal touch and genuine care keeps me coming back!

I've been seeing Dr Nick Bacos since 2014.  At each visit, he listens intently to any concerns and treats every interaction with the care and respect that has kept me coming back.  His approach to treatment is gentle and thorough, and I have left each visit happy and confident in his level of care. 

I recently scheduled an appointment to see Dr. Bacos for the first time after deciding to switch my dentist after 10+ years.  Dr. Bacos was incredibly knowledgeable, thorough and made me feel very comfortable right away.  The entire office staff was welcoming, friendly and very efficient.  I can easily say this was the best dental experience I have ever had.  I highly recommend this dental office to anyone in the Chicagoland area!

This is the best experience I have ever had at any dentist.  I enjoy coming back for treatments knowing that I will be leaving with a healthier, more beautiful smile!  Dr. Nelson is the best!

My family and I have been seeing Dr. Bacos for many years....  myself, daughter, sister, brother, & nephews.  Dr. Bacos & his wife, Dr. Nelson are the kindest people.  They are extremely knowledgeable & meticulous.  You could not find more caring people to entrust your dental care with.  Great staff & the environment makes you feel like you are at a spa.  Love them!
