  • Education: DDS
Having come from a professional art background, Dr. Mantinaos is unique in the world of dentistry. He earned a Bachelor of Fine Arts Degree and pursued a career in drawing and painting. Through art, Dr. Mantinaos developed a deep appreciation for science and nature and, hence, was immediately attracted to dentistry. Dr. Mantinaos earned a Doctorate of Dental Surgery from New York University College of Dentistry in 2000, graduating Magna Cum Laude. After completing a General Practice Residency the following year, the Department of Veteran Affairs Medical Center in Manhattan selected Dr. Mantinaos for a 3-year post-doctoral program in specialty of Prosthodontics. The intensive program afforded him the opportunity to gain knowledge and proficiency in advanced techniques with a wide variety of dental implant systems. In July 2004 Dr. Mantinaos was awarded a Certificate in Prosthodontics. As a prosthodontist, Dr. Mantinaos draws from a variety of materials and techniques to render beautiful smiles. In February 2018 Dr. Mantinaos was a delegate at the first TEDx MIS event during the MIS International Implant Symposium. TED is a Silicon Valley organization known for hosting innovative online talks in the scientific community. A wide variety of out of the box topics were discussed; from digital design and augmented reality in the near future of dentistry to patient centered outcome measures and appropriateness of treatment modalities.


With the ongoing threat of coronavirus, the American Dental Association has issued a guideline that all elective dental procedures be postponed for three weeks. We have decided to follow this guideline and, thus, will be rescheduling appointments starting the week of April 19.

However, to address any dental emergencies that may arise, we will be maintaining office hours Monday through Saturday throughout our Lake Success, Huntington, Howard Beach, Astoria and White Plains locations listed below.

Please be assured that our offices are being operated under CDC guidelines including screening all patients who pose a risk of having coronavirus.

We will also be available via email ( and telephone (855-PHD-CARE or 718-DENTIST) to answer any questions or address any clinical concerns you may have.

We know these are difficult times and want to do all that we can to fulfill our mission to address not just your dental and oral health needs, but to promote your overall health and well-being.

We thank you for your understanding and look forward to seeing you when we resume normal operations . In the meantime, please do all that you can to stay safe and healthy.
