    I was super nervous to get a root canal but Dr. Kowalski and his assistant Caroline made it easy and painless! I even went back to work after the dental work was done. I had to get 2 treatments because of an infection, and the office had my prescription for antibiotics and steroids in quickly. I would definitely recommend this endodontist!

    I went to Mr. Kowalski originally because he was the only one that accepted my insurance that was reasonable close to my house. I am so glad I did. He has gone above and beyond. He even gave me his cell phone (which I used) to reach him during the weekend. He has soft hands and him and his staff walk you through everything they do.

    I had an infected root canal that another Doctor could not figure out where my infection was coming from. Dr. Kowalski found the problem and was able to get down to the root of the issue ( pun intended )...explained everything, nice staff I would recommend

    Dr. Kowalski does not stand by his own work. My son had several root canals performed by him, now there is infection in the root and he won't see him because he doesn't want to allow this to be a free session. He did however take his money for the unsatisfactory work. I do not recommend him. Plus his receptionist is very rude.

    I can't believe I am actually writing a review about my dentist ... but I am! Don't get me wrong ... I still don't like going to the dentist or doctor, but I have to say my experience is worth writing about. I had to get a root canal and was dreading the thought of making the appointment. Dr. Kowalski came as a referral from my dentist and a friend ... so I called and made the appointment. I contemplated canceling as the time got closer, but I sucked it up and showed up. I'm glad I did. Dr. Kowalski and his team eased my fear immediately just by their kindness, compassion and understanding that I was less than enthusiastic. The first part of my procedure is complete and I am feeling relief ... no more pain, but also relief in that I am actually looking forward to going back to finish my procedure. Thanks Dr. Kowalski.
