Gruber & Kostal Dentistry - Yorkville (IL)

5 /5 Curtiss Peplinski: Dr. Michael Kostal extracted two teeth for me and i have never had a more professional and thoughtful dentist as he. Any problem during the procedure was handled swiftly and with the utmost care. An incredible dentist and the only one i will ever entrust with my teeth. Absolutely the best.

5 /5 Amanda Henry: Great practice. Dr. Michael Kostal is very thorough and has taken excellent care of my teeth! Super gentle and easy to talk to about my concerns! Would highly recommend this practice to family and friends!

5 /5 Laurie Allen: Dr Dennis Kostal is an amazing dentist and always does amazing work and always makes sure his patients are healthy. I’ve been seeing him for over 12 years and highly recommend this office. You won’t be disappointed!

5 /5 Andrew Myers: Dr Mike Kostal is the 3rd Dentist in the office now. Son of Dr Kostal. He is there a couple days a week. Do yourself or your family member the favor of scheduling with Dr Mike if at all possible. I never would have made it though my procedure if it were not for him. I have the worst white coat syndrome ! He was great and I owe him for helping me through it. The whole facility is full of great people so schedule with whoever is available.

1 /5 Jed Davis: Pricing went from $300 to $1,900 for out of pocket expenses. I called my insurance company and they strongly recommended I find a new provider. We missed 2 appointments for our 5 year old as well which I completely understand is unacceptable. The receptionist literally yelled at my wife though, no exaggeration. My wife was practically in tears. We went in the next day and handed them $100 cash for the inconvenience and was scolded a second time. Horrible customer service.
