Dr. Janssen owes all of his successes to his loving family, who directly influenced his passion for medicine, and tirelessly supported him every step along the way. Pierce’s older sister, Olivia, is a brilliant and caring neonatologist at Northwell Health on Long Island. His father and role model, Bill, is a committed core researcher of neuroscience and microscopy at Icahn School of Medicine at Mount Sinai. His mother, Christine, is a retired labor and delivery nurse who loyally served Flushing Hospital Medical Center for over 40 years. She now spends her time as full-time grandmother of Pierce’s niece, Reese, and as the compassionate matriarch of the family. These three instilled in him the unconditional love, hard work, and tradition above all else. They also influenced his commitment to treating every patient with the same level of care that he would offer a family member. This philosophy extends into his personal life with his devoted wife, Joanne, and their beloved dog, Boo, who ground him and provide him with daily inspiration as he builds his Manhattan practice.
At age ten, Pierce Janssen watched a documentary about a grizzly bear attack survivor and the series of operations required to rebuild her face. He was transfixed, not only by the patient's dramatic transformation, but by the surgeons' undeniable mastery. He appreciated how their knowledge and craftsmanship helped restore form and function, and gave this woman her life back. He wrote in his fifth-grade yearbook that his dream was to become a "maxofacial reconstructionist." The spelling was imperfect. The conviction was not.
Years later, during medical school, that childhood inspiration became lived reality. Dr. Janssen participated in the care of a young boy from the Republic of Congo who had survived a chimpanzee attack—leaving him unable to speak, drink, or eat normally. Scrubbing in for his twelve-hour reconstructive surgery and following this patient throughout medical school cemented what he had always sensed: plastic surgery is one of medicine's most profound callings. Every subsequent career decision has been shaped by that conviction.
Dr. Pierce Janssen is a product of New York's relentless energy and diverse culture. Born in Flushing and raised in the tight-knit community of Sea Cliff, he comes from a place of hard work, family values, and genuine relationships. A Cornell graduate, he spent early formative years in Ithaca, where he developed the academic discipline and Ivy-League rigor that went on to define his approach to medicine. He returned to Long Island for medical school at Stony Brook University, then completed his integrated plastic surgery residency at Icahn School of Medicine at Mount Sinai. Here he spent six years training at one of the nation's most respected medical institutions and deepening his expertise in both cosmetic and reconstructive surgery throughout New York City's boroughs.
After years navigating New York's medical landscape, he understands the city—its people, its standards, the pace, the discernment, the particular sensibility of New York City patients, and what it means to practice medicine here. That rootedness matters to his patients in ways that are easy to underestimate. Dr. Janssen brings an honest, ethical voice to plastic surgery, offering a refined, humble, and grounded alternative to the ostentatious luxury often associated with the field. He believes that the most profound results come from a surgeon who truly understands the people and the lifestyle of the city he calls home.
Dr. Janssen’s surgical foundation was built at some of the most respected institutions in the country. He completed his integrated Plastic Surgery Residency at the Icahn School of Medicine at Mount Sinai, where he had the privilege of spending six years treating patients throughout New York City, working alongside his unbelievably driven co-residents, and learning from some of the most gifted plastic surgeons in the country. During residency, Dr. Janssen’s interest in aesthetic surgery grew exponentially. He came to believe that outstanding aesthetic surgery relies on sound reconstructive principles, and that his ability to approach reconstructive cases through an aesthetic lens, and vice versa, distinguishes his surgical perspective.
He capped off his academic journey with an aesthetic plastic surgery fellowship at The Cleveland Clinic in Cleveland, Ohio, where he mastered the art of deep plane face and neck lifting, rhinoplasty, eyelid and eyebrow rejuvenation, phenol-croton oil chemical peeling, and other facial rejuvenation procedures. His training has been marked by mentorship from world leaders in the field, particularly in the complexities of the deep plane facelift, rhinoplasty, blepharoplasty, endoscopic brow lifts, chemical peeling, complex breast reconstruction.
Dr. Janssen is an active contributor to the medical literature. This commitment to education is not separate from his clinical work — it is part of the same standard. The surgeon who contributes to the evidence base is the same surgeon who brings intellectual rigor to each patient’s plan of care. He has authored textbook chapters on facelift surgery, upper and lower blepharoplasty, and buccal fat reduction and augmentation. He has also authored over two dozen peer-reviewed manuscripts published in the field’s most prestigious journals, including:
