About Margaret Block MD, FACP

I was born and raised in Queens, NY. After completing medical school at Albany Medical College in upstate New York, I completed a residency and fellowship at Rush-Presbyterian/St. Luke’s Medical Center in Chicago, as well as an additional fellowship at the University of Wisconsin, Clinical Cancer Center in Madison, WI.

I have served as a principal investigator for several cancer studies and participate strongly and actively in many research studies to offer exceptional, innovative care for my patients. I am actively involved in charitable organizations surrounding cancer research, as well as professional medical organizations including the American Medical Association (AMA) and the American Society of Clinical Oncology (ASCO).

In my spare time, I can be found pursuing my passion for photography, enjoying the outdoors, spending quality time with my family and pets, and supporting local charitable organizations including the Nature Conservancy and the Joslyn Art Museum.


As an individual whose own family has been touched by cancer, I consider the diagnosis, care and treatment of every patient as carefully as I would a member of my own family. With my primary interests in clinical practice, I understand the importance of providing the most advanced treatment options to my patients.

    I don’t like having to check in online prior to my visits. But the staff is very helpful in assisting with it. Everything else about NCS is superb. Excellent staff and facility. I love it here.

    Every aspect of care provided by a Dr Block and the staff at the Legacy location has always been excellent! I wish every medical practice/office could run as smoothly and compassionately as yours. Job Very Well Done! Thank you!

    The NP was helpful don't get me wrong but she doesn't know anything other than what's on the charts. When I am.scheduled with Dr Block for an annual follownup, that's who I expect to see, not a NP. Again thr NP is likely.suitable but this happens to me moreso than not so I like to know in advance and I recommend a call in advance to sww if your patient is ok with that or if they want to talk to Block directly. I was probably in the room with the NP for maybe 5 to 7 minutes. Very little questions I did most of the talking and actually had concerns as I had fallen less than a week ago and have Dr Hollins reviewing CY scabs for me. Again I asked all the questions and very little was asked to me so I guess the appt is mainly for breast exam and blood work. I am very happy to be past the worst years of my life, and am happy... but again, it's hard to come back every year anyway... so being mentally prepared is so important, knowing what to expect is all.

    All areas seemed to run smoothly. The lady who did my bloodwork was excellent as I didn't even feel the needle. Dr. Block, when asked about another concern, gave me feedback and recommendations on who to see. I greatly appreciated that information.

    Over the last five years, the reception staff have "upped their game", being friendly and helpful. Thank you for working to make the patient experience better.
  • 07/06/22
    My initial appointment was made by someone else, but time spent in the office was very pleasant and thorough. I felt that Dr. Block took her time with me to let me decide best course of treatment to obtain most beneficial results. The computer registration seemed very lengthy and cumbersome for someone who was raised using typewriters! That could have been streamlined.

    Dr T is a fantastic provider. Paige, Kelly, Erin are all wonderful, compassionate nurses. The lab staff are also very nice and efficient.
  • 08/09/22

    I saw Kaylee today in the infusion area to flush my port. She was so helpful in that she called my doctor to see if they had someone there to access my port when I come back in a few days for a colonoscopy. I had already left, but she called my phone and left a message. I was worried that that I would have to come back to the cancer center to get it accessed. She took such a weight off my shoulders. She went out of her way to help me!!!

    LOVED the PA First time I met her she was Fabulous
  • 06/21/22

    The new online check-in has issues. Two days prior to my appointment, I checked in online and the day of my appointment I checked in at the counter to let them know that I had arrived and then I sat down in the waiting area. Twenty minutes later, I received a call from one of the nurses asking me if I had arrived and if I was in the lobby. I said that I had checked in 20 minutes earlier and was in the waiting area. She said something about not receiving a "yellow paper" and within a couple of minutes my name was called. The nurse that took my vitals apologized about the wait and told me that this had happened to other patients as well and this was a new system.
  • 09/01/22
    appreciated the speed for how I moved through my appmt, was actually out of there before my last appointment should have begun!
  • 09/09/22
    Paige is my nurse and she is excellent! The volunteer Marina was extremely friendly and helpful! And Jeannett drawing my blood was also super!
  • 09/22/22
    I did the on line check in. It would be most helpful if a person is told photos front and back of all insurance cards and photo ID would be needed to complete this check in.

    Colleen nurse practitioner was so helpful and took her time to explain and listen.
  • 10/27/22
    Facility is wonderful. Beautiful for those of us who have cancer.
  • 10/21/22
    I just had a blood draw. It was timely and painless.
  • 07/25/22
    I have always found the Doctors and supporting staff to be very professional, discrete, patient, efficient, and kind. I hope my friends and family don't have to experience cancer, but since it is a medical issue that has yet to be eliminated, I would recommend Nebraska Cancer Specialists.
