I have been with Dr Seeeney since 2012 and 2 diagnosis of breast cancer. He is an amazing specialist. I have always felt like he is has my best interest at heart. He is a caring and compassionate physician with so much knowledge. He is able to deliver that knowledge in a honest yet sensitive way. E has been a positive model in my journey.
