“Dr. Kolnick is amazing”
I have worked in the dental field as an assistant and/or receptionist for 30 years - I know a thing or two about dentists and dental offices. Dr. Kolnick is in a league all his own. His offices are well run, meticulously clean and staffed with wonderful, caring people. He diagnosed my problem on my first visit with him, after I had seen several other dentists/specialists over a one year time period- many of whom advised me to have my troublesome tooth extracted. He performed the needed surgical procedure to save my tooth and, due to his high level of expertise, I experienced absolute minimal post operative discomfort. He shines the brightest when he's performing surgery. I am so happy I found my way to Dr. Kolnick and if his offices were closer to me - I'd apply for a job!

“Excellent experience”
Dr Kolnick is an experienced, professional and caring doctor. I felt like I was in good hands. It's unusual to find a doctor who is both very capable and is also kind and soothing - Dr Kolnick possesses both qualities. The office maintains very high cleanliness standards and seemingly state of the art technology.

“Root canal easy? Yes!”
Dr. Kolnick was very gentle, and calming when retreating two infected root canals (previously done elsewhere.) He truly made a potentially horrendous experience very, very easy. I hope to keep these two teeth for a long time!

“I'll never fear root canal again.”
Dr. Kolnick did a wonderful job of putting me at ease prior to working on me. He was gentle, compassionate, funny and skilled. My appointments went by very quickly and painlessly. I would recommend him to anyone in need of root canal therapy.

Comment - “ Dr. Kolnick is amazing ”
I have worked in the dental field as an assistant and/or receptionist for 30 years - I know a thing or two about dentists and dental offices. Dr. Kolnick is in a league all his own.
