Dr. Marqusee has truly been pretty much the top three of doctors that really take the time and listen and the cancer was very unique and she has stuck with me through everything, including loss of vocal cord and weird blood work sometimes and I cannot, cannot let Brigham and Women know enough how lucky they are to have her. What a fabulous doctor.

I consider myself very fortunate to have Dr.Marqusee as my endocrinologist.
