"Nurse/Navigator Lilliana Borelli RN was the BEST of all my experiences from pre-colonoscopy scheduling to post operation follow up.  Lilliana Borelli was there to greet me as promised at the new Cancer Center for my appointments with doctors Lee and Zhang.  Lilliana Borelli introduced me to financial aid at my request easing a lot of anxiety.  Lilliana Borelli was amazingly responsive.  If not picking up my phone call, calling back almost immediately answering my questions. If it was an unspecified time she would get it and call back right away.  I was NEVER left hanging.  Lilliana updated my wife post procedures always.  Lilliana Borelli's exceptional attitude, caring, patience, among many many more is amazing.  Dedicated workers such as Lilliana who love their work and job and serve are what makes Stony Brook Hospital and the new Cancer Center the best in medicine.  Lilliana is a perfect example for everyone." - Charles M.
