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.

    Being told you have cancer is a major shock to the system. First you have to question what you thought you heard.....oh you said cancer and then your mind goes blank. You can't think of a single question and if you did would you understand the answer? The whole team starting with the staff setting your appointment, the nurses, lab techs and my doctor, Dr. Block. I had confidence in the treatment because of the confidence I had to each and every team member I had contact with. Their knowledge of the drugs, how they may effect me. They walked with me through the treatments. I could go on, but most of all was the support and confidence. I felt safe even though I knew there were no guarantees.
  • 07/05/23
    Caring, efficient staff.

  • 05/25/23
    Scheduling with some occupational therapists is difficult, with last minute & unfortunately regular instances of cancelling my appointments. Which then causes issues with my care, and makes existing problems worse. However, todays visit was great with Rachel! My trunk/arm/nerve pain/lymphedema was vastly improved after her treatment.
  • 05/25/23
    Everyone was helpful and kind.

    Dr. Block was very nice and professional. She also made me feel heard. She genuinely listened to my concerns, asked me a bunch if questions took her time, educated me on things I may not have known. Also the lab tech who took my blood was the most painless stick I can remember I'm years. She was a nice lady with glasses and light brown curly hair but I don't know her name.

    Olivia and Pam in reception very nice to work with. Heather working with me on my Hormone Blocker Study is excellent. Dr. Block has been very helpful and encouraging with my cancer journey.
  • 06/24/22
    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.
  • 09/30/22
    Dr T is a fantastic provider. Paige, Kelly, Erin are all wonderful, compassionate nurses. The lab staff are also very nice and efficient.

  • 08/29/22
    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!!!
  • 06/14/22
    LOVED the PA First time I met her she was Fabulous
  • 06/21/22
    Always a great experience. Every person there has a smile and something nice to say. I am very thankful to be in your care
  • 08/29/22
    Everyone I talked to was very pleasant and helpful.
  • 10/12/22
    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.
  • 10/19/22
    Thanks !
  • 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!
  • 07/14/22
    I really like the Legacy facility! I’ve went to Estabrook for 16 years with my Dr. Block. Her move here brought me here. Back during my chemo we did visit here as our favorite oncology nurse, Wendy had transferred here. I love the idea of tablets provided! Tablets weren’t around 16 years ago! Very great facility!
  • 07/26/22
    Dr. Geetha was great! She listened and she explained. I appreciated her style and her experience. I felt comfortable asking questions. Staff didn't take me for labs first, so I did them after my visit with Dr. Geetha... I do not know those results yet.
  • 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.
  • 06/20/22
    IK am not internet wise & thanks for front desk girl for help to pre enroll again. Need some easier way for us seniors--

  • 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.
  • 08/02/22
    I love coming to the Legacy office for my treatments. I know Dr. Block and the staff will go above and beyond to help me and make me feel comfortable and well taken care-of. Keep up the great work!

    I have already recommended the facility and Dr Block to several friends and friends of my family. They have not always had Dr Block but have been very happy with the oncologist and the facility. I feel God; my move to Omaha closer to my daughter and her family; and the care I have received from Dr Block and NCS has been instrumental to my still being on this good earth for these past 6.5 yrs. Thanks to all staff and administration for you care and kindness.

    Whenever I have an appointment I am always asked how I am doing with follow-up questions. Everyone seems to really care about me and how I am doing. I always feel at home. Since I was diagnosed over 5 years ago, I have felt comfortable asking questions and having them explaining procedures until I understand. My care providers fill me with confidence that I am going to the right place and recieving the care that is most beneficial fo my care.
