Honestly, the girls at the front desk were so polite and professional right from the start. The medical assistant was friendly too, which really helped calm my nerves. Dr. Desse made me feel totally confident in him—he was professional and did a great job with my root canal therapy in Swansea, IL. After the numbness wore off, I was completely painless. Couldn't be happier and would definitely refer Dr. Desse to anyone needing endodontic treatment around here. Thanks to everyone in the office for making it such a smooth experience!

Dr. Desse is very skilled! His assistant (sorry I forgot her name) is outstanding too—she's spot on with her skills making those root canal appointments as easy as could be. My two root canals done recently in Swansea were a breeze. The doctor is good at explaining what to expect, and even when I got nervous about feeling something, his response helped calm me right then. Great endodontic treatment here in IL.

As a referring dentist myself needing my first ever root canal, I chose Markarian & Diliberto in Swansea because of the great feedback from my patients and the excellent care I see them get. So glad I did! They were professional and friendly, and the procedure was quick, easy, and painless. Not a bit of pain after either. Don't want another root canal soon, but if I did, I'd know right away who to see in Illinois. Thanks again! ❤️

Went to Dr. Markarian in Swansea for a consultation about possibly redoing a root canal. Office management was kind and thorough—something you don't see too often these days. The young lady who took the X-rays was very kind too. Dr. Markarian took his time explaining everything about my tooth, had a great chairside manner, and didn't push me into using 3D imaging. He gave me a few options and good advice for endodontic treatment. Definitely would recommend this endodontist in Illinois!

Always felt anxious about dental stuff, and this was my first root canal. But the team at this Swansea office made it way less intimidating than I thought. They explained each step, worked efficiently, and were consistently kind and reassuring. Had minimal discomfort once the anesthesia wore off, and in the days after, little to no pain. Recovery went smoothly with the endodontic treatment here in Illinois. Really appreciate the care and professionalism.

I arrived on time. Filled out paperwork. Front staff kept me posted. They were just a bit behind but not as bad as some offices. Dr. Diliberto was professional yet personable and explained my procedure. I just wish I could get in earlier but there are only so many hours in a day!

The receptionist and office staff were very pleasant—not many offices are anymore, and that set a positive vibe for me. Dr. Jack Desse performed my surgery in Swansea; he was professional, explained everything, and incredibly gentle. On day 2 of recovery with very little pain. Will be having a root canal next and he'll be my choice for that procedure in Illinois. Grateful to have been referred to this office for endodontic care.

My daughter who has never had dental work done in her life aside from cleanings and X-rays, found herself needing some work done on two teeth. The consult and procedures were done with great care and my daughter felt very comfortable throughout the whole process. We would highly recommend this office and their staff to anyone needing their services.

I had a great experience having a root canal performed by Dr. Jack Desse. He was very professional and likable. I felt very confident in his ability to perform the procedure. Not having a root canal performed previously, I was anxious. However, with the aid of his assistant, the procedure went smoothly. I did not experience any pain or discomfort. Afterwards, any pain I felt was minimal and was treated with OTC medication. I highly recommend Dr. Desse and the dental assistant for your dental needs.
