Treatment Philosophy

I am excited to be part of the multidisciplinary care at Fox Chase, and to work to improve patients' outcomes. Since endocrinology intersects with all of the other medical disciplines at Fox Chase, I get to interact daily with all my colleagues. I am truly honored to be able to help when cancer treatment affects a patient’s endocrine system. When a patient comes to see me, they can be anxious, depressed, and worried. And my goal is that they leave their appointment with a smile on their face, relieved because they know there’s a solution to it. Fox Chase has a solution to it.

    My appointment was at 3:40 pm and I was forgot about and not seen until 4:40pm. I was listed as a male on my chart and I am a female! I did not feel that all my results were examined carefully and I felt that the team was exhausted at the end of the day and I felt I did not get all the information that I needed to make a decision about my health. I will get a second opinion else where. Very disappointed with Fox Chase!
