That level of knowledge and dedication is rare.I honestly cannot imagine a better doctor than Dr. Topp. I trust her completely with my health, and I am incredibly grateful and privileged to be under her care.

My only issue was my appointments were getting scheduled automatically without talking to me first to schedule the appointment. Not sure what is going on with the scheduling department but I had to have my account flagged so it doesn't happen again. Otherwise everything else is amazing!

Providence Patient
I have been dealing with a very low grade of breast cancer. EVERYONE at St. Vincent was treated me as if I was the most special person. I thought about wearing a tee-shirt that says "Got breast cancer? Go to St. Vincent's!" but I won't! I will however encourage anyone I meet to use St. Vincent's.
Providence Patient
Dr. Topp is usually great about explaining things carefully enough that I follow along easily. At this appointment she explained my treatment options so quickly that I was glad I'd done research ahead of my visit and already knew some of the details of what we were discussing. A printout further explaining my options would have been helpful.
Providence Patient
From the front desk, to the nurse who first spoke with me, to the doctor, and then the people where I needed to schedule my mammogram and tell me of another appointment, all were extremely understanding and user friendly. When people are so understanding of a situation its makes it very easy to ask questions.
Providence Patient
Dr. Topp is an excellent oncologist and is very thorough when we meet. I also like that she uses her phone to capture our appointment which means she is listening and engaging with me and not having to write or type during our appointment. I also feel like the post visit information she captures is more thorough and I wish that more of the providers I see at providence and elsewhere would do this type of information capture during appointments.
Providence Patient
Thank you for excellent care
