It is with profound sadness that I inform you of the unexpected passing of Dr. Peter Harnois, a beloved dentist at Hinsdale Dentistry. Dr. Harnois dedicated 41 years to providing compassionate and exceptional care to patients, as well as educating fellow dentists around the country on emerging technologies in dentistry utilized in our practice.

We understand this news is very difficult to receive. His loss is deeply felt by our entire team. His family will be holding a local memorial in the coming months, most likely late February or early March. Once finalized, details will be provided by Sullivan Funeral Home.

If you would like to read Dr. Harnois’ obituary written by his family, you can find that here.

As we work to transition, our first focus is you, our patient, and ensuring that your care is as smooth and seamless as possible. Our entire Hinsdale Dentistry team is committed to providing you with continued, focused advice and treatment to give you the best customized care to meet your dental needs.

If we have not yet met, I joined Hinsdale Dentistry in July 2013 after completing an Advanced Education in General Dentistry degree and a fellowship from the International Congress of Oral Implantologists. I became Dr. Harnois’ partner in 2016. I look forward to serving every patient in our practice and to developing lasting relationships built on trust and excellent patient care.

I encourage you to reach out to me or Donna Vranas, our Practice Manager, with your questions or concerns at our office at (630) 323-4468. We appreciate your patience and understanding in the coming months and look forward to seeing you at your next appointment.

Sincerely,
Michael J. Kowalczyk, D.D.S.
& Hinsdale Dentistry Staff
