Meet Dr. David J DeMarco

For Dr. David John DeMarco, dentistry is more than a profession, it is a calling that provides him with a sense of accomplishment and the opportunity to connect with people from all walks of life. He values the social interaction and diversity that comes with his work, keeping him balanced and grounded while addressing patients’ unique concerns and expectations. He takes pride in making a difference in patients’ lives, whether by keeping them healthy, relieving discomfort, or restoring a confident smile.

Dr. DeMarco is especially gratified by comprehensive treatment that brings deteriorating dentition back to proper form and function, which not only improves oral health but also gives patients the confidence to smile and speak comfortably again. He also enjoys the mechanical and creative aspects of dentistry, which allow him to apply his skills in innovative ways.
