About me
Philosophy of care
The diagnosis of cancer marks a defining moment in anyone’s life. Dr. Colocci believes that treatment must support the patient’s whole well‑being. She values communication, respect, and professionalism, and she strives to explain each diagnosis clearly while identifying the treatment that best fits both the disease and the patient’s individual needs. She is committed to using the most current and effective therapies while maximizing quality of life. From the moment of diagnosis, she serves as an objective and compassionate guide for the patient and their loved ones throughout treatment and in the years that follow.
Personal interests
Outside of Medicine, Dr. Colocci is married and has two children. She enjoys playing the flute (Music Conservatory graduate), skiing, hiking with her Australian Shepherd/Golden Retriever mix, and spending time in Italy. Currently, she is having a hard time trying to learn how to wingfoil.
