Dr. Fine is often asked “What keeps you going so long?” his answer is always simple and heartfelt – he thrives on the love for his patients and his profession. He has served as the owner of One Fine Smile, which stood as a dental practice many years before Dr. Fine made the purchase, in fact, at over 90 years old this is the oldest existing dental practice in Oak Park.

Although Dr. Fine’s office has historic roots, the dentistry offered here is done with the latest, cutting-edge technology and most advanced procedures available in the field.

In his spare time, Dr. Fine loves to spend time with his family, especially with his grandchildren. He feels truly blessed to have had the opportunity to spend so many wonderful years taking care of his patients, who have become his ‘second family.’
