PRACTICE UPDATE: Welcome Dr. Hardenbergh

Dear Valued Friends and Patients,

We have some exciting news for 2022!

I am pleased to announce the addition of Dr. William E. Hardenbergh to my practice.

I have thoroughly enjoyed doing dentistry for the last 47 years and my relationships with all of you as patients and many that are friends.  The time has come, however, for me to partially relax my work schedule and enjoy some extra time with my wife and family.

I’m happy to introduce Dr. William Hardenbergh as a great young dentist and partner to help me accomplish my goal. He is a caring, talented, and compassionate professional who shares my commitment to exemplary dentistry.  I was looking for a partner who would provide care to you as I have and I feel that I have found that person in Dr. Hardenbergh.

Dr. Hardenbergh graduated from the prestigious Tufts University School of Dental Medicine, in Boston, MA, and has been in private practice since graduation. He has also been actively involved with numerous non-profit organizations to provide dental care to those less fortunate.

Dr. Hardenbergh brings a wealth of experience and knowledge of the latest dental technologies to the practice, including “Crowns in a Day.”

The office staff has met with Dr. Hardenbergh and they also are enthusiastic to have him in the practice.  He is a great fit for our team and, most importantly, to you as my patients.

I have had the privilege of serving many of our families for 3 generations! My patients have given me the highest compliment bestowed to a dentist by providing referrals of their family, friends and coworkers. I am sincerely grateful.  We have the best patients in the world!  Your support of Dr. Hardenbergh and continued referrals to our practice would be the ultimate compliment.       

We look forward to seeing you in 2022!

Comfort and Technology

Our dental office is designed with your comfort in mind: expansive treatment rooms with features such as an intra-oral camera that allows the patient to view the mouth exactly as the doctor sees it, modern sterilization techniques for your safety, drill-less removal of tooth decay using microabrasion, laser technology to find cavities while they are still small and can be corrected with minimal treatment, digital x-rays for immediate viewing and significantly less radiation exposure to the patient, and relaxing nitrous oxide and oral sedation for apprehensive patients.  These are just a few examples of our commitment to providing dental care in a comfortable setting.

Caring, Compassion, and Excellence are Our Goals

Our entire staff is dedicated to providing quality dentistry.  We take the time to talk with you about your concerns and desires, then provide you with the complete dental care you deserve in an environment that is as pleasant as possible.

We believe that good dental health is important for everyone...children, adults, and seniors.  We stress preventative care with the goal of finding and treating dental problems while they are small.  Part of our commitment to serving our patients includes providing information that helps them to make more informed decisions about their oral health needs.  This website is a resource we hope you’ll find useful.

Covid Precautions 

As we navigate through the world of Covid 19, we have established additional controls to keep our patients, staff and families safe.  Some of the additional protocols include: restricting the use of the waiting room by asking that our patients call from their vehicle before entering the office, equipping the office with multiple medical grade air scrubbers as well as special patient evacuators to greatly reduce aerosol dispersion, and increasing the level of personal protective equipment that we use.  Your safety continues to be our priority. 

You’re Invited! 

Whether you’ve been with us for years or you’re visiting for the first time, we’re excited to welcome you to our dental family. We proudly serve the communities of Schaumburg, Hoffman Estates, Palatine, Rolling Meadows, and the surrounding Illinois areas. We thank you for allowing us to take care of your dental needs and look forward to serving you.
