• My experience with Dr. COSTENBADER is always perfect. She is knowledgeable. She's smart. She's nice. She knows all about my history. She follows up on everything. She's the best. I couldn't ask for better. I couldn't ask for better care. So I could not be happier with Dr. COSTENBADER . And I hope I remain seeing her for as long as she's, you know, as long as she's in that hospital. So that's about it. Thank you.

• Dr. Costenbader is an excellent provider. I have a complicated medical history and she takes the time to discuss, asks questions, keeps a watch on my labs, orders necessary tests, and provides follow up with other specialists. She is also exceptionally responsive via the portal. I am always amazed at how she takes the time to personally respond.

• I feel very comfortable working with Dr. Costenbader. She is just very empathetic to what's going on with myself, with my medical condition. I feel completely 100% confident with her being in charge of my care and sending me to other areas to get things checked out. For me to come home with a young family knowing that my medical is being carefully looked after means a lot to me.

• Dr. Costenbader goes above and beyond to follow up and make sure I feel comfortable, and you can tell she really cares. She listens, she explains things clearly, and she never makes me feel rushed. I always leave feeling supported and looked after.

• I have been a patient of Dr. Costenbader since 2000ish. [redacted] She did not review my medical notes before I arrived and appeared puzzled at what has been going on with me medically over the last two years despite my oncologist having contacted her in the summer. I was very, very disappointed at how rushed our appointment was.The session was interrupted 5 times with phone calls she answered. Also, at the end of a short session with her, she was rushing out the door as I continued to talk with her about future treatment. I would gladly schedule a double session with her if I could have her undivided attention.

• I have known Dr. Costenbader for almost 10 years, and I feel like she has the best handle on what is actually going on with me, and I've had a very complicated medical course in the past three years. I feel that she really takes the time to know what's going on, and I trust what she says. She always follows up, and I really appreciate her.
