The (my) King of Dentistry

I wrote this review once before in a lengthy indulgence of my appreciation for Dr. Griesbach. And I felt it was time to revisit my accumulative experience years later, about my oral hygiene elected dictator - of the best kind.

I think anyone stepping foot into a dentist's office would want a caring and compassionate experience. A dentist who is looking out for your best interest financially and most importantly your health. And also not looking at you as a cash cow to fund their next sports car. Dr. Griesbach is a sweet, caring and genuinely cares about your long term health in only doing what’s truly right for you. Doing only what you NEED and not selling anything you do NOT need. But at the same time referring you to his favorite specialists when something is out of his scope and absolutely needed. He is very particular with his referrals so you can always have a calm piece of mind.

Although he is not a pediatric dentist by resume, my 7 years will tell you otherwise. But that is a testament to how gentle and skilled Dr. Griesbach is with even the mini-patients. I grew up with a butcher dentist who caused me an incredible amount of trauma and anxiety so stay the very least. Luckily I connected with Dr. Griesbach later in my teens and have never again had that sinking feeling in my stomach - for days prior to an appointment. I actually look forward to my appointments - which is something I never thought (in my younger years) I would ever say in my lifetime.

If you reading this and dreaming you had a dentist like this - I got it completely - they do exist. Or if you reading this and you have a dentist like Dr. Griesbach - you know what I am talking about - hold them close to your heart as you know how good you have it.

And a big shout out to the staff which is always so on top of admin and assistance - never a single issue - always warm and welcoming. Every king is never without a great staff...

Outstanding point of care and restorative dentistry! I’ve been a long time patient of the excellent Dr J Griesbach and have not been to him for five years, as a chipped a couple molars in the last year or so and decided to go back and make an appointment to take care of my oral health. I was sad Dr Jim recently retired but could trust his experienced colleague and recommended Dr John Hartmann, who I met yesterday and hoped he could restore the badly damaged 2nd molar in my lower left jaw. I was amazed at his dexterity, his wisdom and skill, educating me (after full X-Ray) that the other two adjacent molars also had serious decay/issues. Thus, I gave him the green light trusting in his expertise in restorative dentistry and dental medicine to work on all three! After an hour and a half, he restored (and saved the primary chipped molar) ALL THREE molars! I did not need a crown which I feared would be the case! I left very grateful to Dr Hartmann and his assistant Abby as I literally got a perfect new set of molars! The occlusion is perfect and now I don’t risk biting or getting any further decay or infection. Dr Hartmann and his staff are highly skilled and offer gentle dental healthcare in a state-of-the art clinic and clean environment. I am eternally grateful to Dr Hartmann, an excellent dental healthcare practitioner and educator! Highly recommended dental clinic at OB Dental...

October 2025 Update: Unfortunately, this beloved practice has undergone some drastic changes. None of the doctors are at the practice- and only 1 trusted hygienist remains. The level of care, personalized attention, and trust does not exist. Sadly, I think it will be time for us to find a new dentist, one that does not actively look to drill in your mouth for the smallest unnecessary assumption. I wish Oakbrook Dental Group all the best- but this is no longer the practice we loved.
