Dr. Cassell is passionate about her patients and her practice. She sees her doctor-patient relationships as multi-faceted and long term.

She regularly lectures and plays an integral role in the surgical training program at Lenox Hill Hospital.


Lauren Cassell is not only a gifted diagnostician, surgeon, and teacher but she is also a devoted wife and loving mother. She understands the wide range of issues that her patients must face, not only for themselves, but also for their families. She views her patients as people, not diseases, and she always takes the time to treat the entire patient.


"I love my work and consider the ability to practice medicine a privilege. Every day is challenging and gives me the opportunity to meet interesting new people and help them through a difficult time in their lives. The good news is that the vast majority of my patients continue to lead full, productive, happy, long lives. Yes, there are tears, and we keep a lot of tissues on hand, but in the end most leave happy and excited about their future. I am so very lucky."
