Dr. Frank DiCicco, DMD

Owner & Head Dentist

Dr. Frank DiCicco brings a sense of focus, passion, and vision to his practice of dentistry. Dr. DiCicco provides exceptional dental care and seeks to make the dental experience pleasant and painless for all of his patients.

Dr. DiCicco had his undergraduate education at San Diego State University, and then Temple University School of Dentistry where he had achieved honors from the Periodontal Society and the Stomatognathic Honor Society. Before he had relocated to New York City, Dr. DiCicco owned and directed a successful dental practice in Philadelphia for nine years.

Presently, he owns and practices in dental offices located in New York City (in Manhattan and Staten Island) and New Jersey.

Dr. DiCicco understands that the general population often overlooks the importance of regular dental care. By bringing a new, state-of-the-art mobile dentistry service to the community at an affordable rate, dentists can now focus on quality patient care, while patients can focus on their level of comfort.


Diana Ji, RDH

Founder & Chief Managing Director

Diana has been working in dental healthcare for almost a decade. During her college years at Syracuse University, she had been a dental assistant and administrator. Since then, she found a new passion towards dentistry and patient care, which led her to continue her studies in Dental Hygiene at SUNY Orange.

Although Diana has been a professional hygienist for over 5 years with many accomplishments to her name, her true passion for dentistry is not to be the best teeth scraper in town, but rather to be able to impact the lives of her patients at a much deeper level.

After hearing the challenges that some of her patients face in finding quality dental care at their convenience, she decided to find ways to alleviate this problem, and that is to create an effortless and seamless way of delivering dentistry to people’s homes. Through the advances of technology and digital world, she hopes that Smiles Delivered's on-demand mobile dentistry will become a new norm of receiving quality dental care for everyone.
