I am very happy with Grand Avenue Dental including the dental care of prophylaxis/cleaning with Heather and the dentist check by Dr. Aiuppa who explained he will continue to watch the very old fillings and the why and when of a recommendation to replace them that could come in the future.

Feel confident I am receiving a high level of care from Dr. Aiuppa. Also very pleased with the care provided by Heather. Perhaps the most thorough & thoughtful treatment I have ever received from a dental hygienist. Overall I am very satisfied with the entire staff at Grand Avenue Dental.

Wonderful staff who are very proactive in making the patient feel welcome and appreciated. Dr Bayer and Dr Fahl are protectionists who make sure that the work they do is right and that the patient leaves happy. If you have an issue they will usually get you in that day but always by the next day. I have had numerous crowns and an implant finished with them and they are perfect. You will love this practice.

Always a pleasurable experience. The facility is very clean, and the staff are always super friendly and accommodating. Couldn’t imagine going anywhere else. I have been a patient for well over 50 years. My wife and kids all have gone here. Thanks for years of awesomeness Dr Fahl and Dr Bayer!!

A very professional and friendly office. Dr Bayer is extremely gentle and caring, and willing to share a detailed explanation of any concern at your visit. Heather, my hygienist, is involved with a patient as an entire person with the details of your health, and how it may affect your dental care. I am happy to be their patient.
