Dr. Grassa is a dedicated and compassionate general dentist known for his calm demeanor and commitment to providing high-quality, patient-centered care. He earned his dental degree from Temple University School of Dentistry in 2018 and went on to complete his residency at St. Luke’s Hospital, where he further advanced his clinical training in general and restorative dentistry.

Dr. Grassa’s journey into dentistry began unexpectedly in the 8th grade, when he took an aptitude test that suggested “oral surgeon” as a potential career path. Curious, he began researching related professions and came across the field of general dentistry. As he read more, a friend looked over his shoulder and asked, half-jokingly, “Why on earth would you want to be a dentist?” The question stuck with him—not because it cast doubt, but because it made him reflect on what drew him to the field in the first place.

He recalled the calm and reassuring nature of his own dentist growing up—how visits to the dental office were never intimidating, but instead felt safe and familiar. That sense of trust and connection inspired him to pursue a career where he could provide that same experience for others.

Originally from Lindenhurst, Dr. Grassa now resides in Massapequa with his wife, Nicolette, and their daughter, Giuliana. Outside the office, he enjoys spending time in nature and staying active through fishing, archery, hiking, and golf.

Dr. Grassa takes pride in building lasting relationships with his patients and helping them achieve healthy, confident smiles in a comfortable and welcoming environment.
