Patient comments
Dr. Cohen is great!
Dr Cohen is THE most compassionate doctor that I ever had the pleasure to work with. She was my radiologist during cancer and I am now 6 years cancer free. I have been under her care for 6 years for follow up and this was my last appointment. She was still has the same amazing "bed side manner" kind and caring doctor that I first met 6 years ago. Always truly concerned, never rushes you, always listens and advices. She checks on me, not just for cancer questions, but ALL my other follow up doctors as well. Glad this is behind me now, but I will NEVER forget her kindness!! [...]
I am very pleased with this provider and the whole Fox Chase team

Very good service.
