Dr cook is an asset to your staff. I am very informed about medical matters. Add Cook is intelligent and thorough. At the same time he is sensitive. I came to Geisinger for him. I stay for his care.

dr Glendon cook is an asset to the Geisinger health system. I have recently moved to drums pa and travel 40 minutes just to continue care with him. he is very friendly,caring, and patient with his patients! he deserves more recognition than this survey him and his nurse Pam are the best in the Dallas clinic
Sep 18, 2015
As long as Dr. Cooke is my doctor, and he personally attends to me, I will stay with Geisinger.. Once the greedy corporation takes over, I will leave!!! I'd rather go to a witch doctor than be treated like cattle being processed for slaughter..
Sep 16, 2015
I have already recommended Dr. Cook to several people. He reviewed my chest xray with me, reviewed my lab work and discussed concerns and worked with me to an agreeable solution

Dr. Cook is absolutely wonderful! I moved from Intermountain Medical Group to Geisinger because I wanted Dr. Cook as my primary physician. I met him when I was the primary caregiver for my mother in law and he was covering for her primary physician when he was on vacation. I was extremely impressed by his professionalism, empathy and willingness to ensure my mother in law was understanding everything he was explaining and showed that he truly cared about her as an individual and not just a patient. (Especially with her not even being his patient.) I was so impressed by Dr. Cook that it made me realize how substandard my own physician was over the years, so I requested Dr. Cook as my new primary physician and he accepted me as a new patient. I cannot say enough about how he treats you like a person and realizes your anxiety and concerns and ensures he treats the WHOLE person and not just the symptoms! I wish all doctors lived up to his standards!

Having a hard time getting a call back on test that was taking.

Geisinger has been very impressive to me since I had and began raising my two daughters. They both know how comfortable I am with the treatment my older daughter, Linda, was given at the Danville Hospital for hearing problems when she was young and in grade school. For myself, I am much happier with the doctors I have used there over the years and would never consider changing from Geisinger.
June 22, 2015
*Dr. Cook was very professional and calming. Made me comfortable and answered all questions. A true asset to this profession.

Apr 10, 2015
Follow up wasn't the greatest. I had to request an X Ray we discussed. Four days after the X Ray was taken I still haven't heard of the results.
Apr 8, 2015
Resident dr. I was strongly encouraged and only one made available for me to see, despite my request for MD. Not DO she "seemed" fine but doesn't not "listen" to what you try to relay. Just strongly urges. (W/o alternative) to do as instructed. Makes light of problems you are concerned or subjected to compromised state of health, despite your "input & pain".

Dr Cook is awesome.

It seems like the care provider wants to prescribe pills for everything not an alternative methods.

Dr Cook is not only a suburb physician but a nice human being as well
Feb 20, 2015
Dr. Glendon Cook is a very caring and extremely sharp professional. I feel that I am fortunate to have him as my primary health care provider and I value his judgement in assessing my Heath care needs.
