Have known Dr. Kosek for some time. He always responds to my concerns and explains treatment options carefully. I trust his expertise and advice.

Dr. Kosek is an excellent - doctor never have any problems with him. Good listener.
Dec 15, 2016
Dr. is very busy, as you could tell from such a wait for a 9A appt. but there was a family matter that I needed advice with and he stopped what he was doing and gave complete attention and sound advice on how to deal with this problem and cope with the issue. He does care, but is overworked, and I know this from seeing him so many years and what he goes through...

Dr Kossak always takes time to sit and talk to Da . he doesn't hurry and he listens to what Dad has to say. We are very pleased with the care Dad is receiving.

Dr Gunnar Kosek is the best - never rushes, explains in simple words and never forces me to do tests. He waits till I'm ready to have them. VERY KIND & FRIENDLY!!!

Dr Kosik is a wonderful doctor, I wish I met him years ago.
Oct 26, 2016
As someone who has worked in a profession that required excellent customer service I appreciated when I receive the same type of service.
Oct 26, 2016
Doctor asked me lots of questions, and really did care about ME!! I just felt bad that there were so many patients waiting, and took so long. How can a doctor care so much if they are rushed? And did he miss asking me anything? I love this doctor, not many that, cares about the patient...

because he takes great care of us, I don't mind the wait.

Dr. Kosek very interested in my conditions and completely explains plans kind and caring.
Aug 24, 2016
While I have no problem with this provider, I would not recommend this clinic because of the telephone difficulty noted above. Not enough doctors for the patient demands on this office. No time to respond to "mygeisinger" messages or follow-up matters. I am contemplating making a change, which is difficult after all these years.
Aug 12, 2016
Dr. Kosek was outstanding. Took time to explain drugs and why he recommended changing some of them and discarding some. Very thorough and extremely knowledgeable about my conditions. Explained my drugs and their use and effectiveness. I have never had a physician explain things to me like he did. I really look forward to my care by him.
Aug 12, 2016
Just want to say that Dr. Kosek is a very caring Doctor and I think he's terrific

Jul 26, 2016
i like my dr.
Jul 26, 2016
He seemed not wanting to be bothered. No follow up was talked about and felt as though he didn't care. I will switching clinics and doctor.
Jul 20, 2016
Excellent doctor in all aspects.
Jul 12, 2016
Dr Kovalick is my PCP and I was seen on an emergency basis by Dr Kosek. My biggest issue I had was the wait time which the doctor blamed on the requirements of the electronic medical record.
June 14, 2016
removed a skin tab from my face in the office. Good results.

Dr. Kosek was very professionala personable. He spent quality time with me and gave me additional information about possiblec conditions. He ordered labs to test for a condition relatedt o other medical problems.
June 1, 2016
I have recommended Dr. Kosek to other people looking for a primary care doctor.
June 1, 2016
Although the doctor we did see was good as we have seen him before and none of this was his fault. The doctors should not tell you to come back in 2 days for follow up if you can get an appointment.
May 20, 2016
Did not rush thru the visit, took time to answer all my questions and concerns.
May 18, 2016
Once again, much almost as good as fla. Health First this yr. Last yr your staff was overrun.

I always mention the good thoughtful care I receive from Dr. Kosek _____ staff.

Always turn people away from Geisinger.
Apr 22, 2016
dr. K is very professional and completes all task in that manner
Apr 5, 2016
Dr. Kasek is an excellent and very caring doctor. Sorry to see my time with him seems shortened because of the overwhelming amount of patients he has to see now.
Apr 4, 2016
I have found Dr. Kosek to be very kind and competent. He shows empathy and listens intently to ones concerns and takes the time to make sure all questions are answered so you can understand them and you always feel good after your visit that you have someone who cares about you and will always do what's best for you.
Apr 1, 2016
I could tell he was busy and I felt very rushed. It was probably the shortest doctors visit I've ever had. I also felt he diminished my problems rather than reassuring me.
March 11, 2016
I felt that, I could have talked to the doctor a bit longer. I know he has a time limit, so I know he had to get me out of the office. It made me feel good that this doctor took the time to show that he cared enough to talk to me with the little time he had to spend with me without getting in trouble. This doctor is one of the very best that I have ever seen. I hope to have him as my doctor for a real long time!

I have had two outstanding family Drs., Dr. Nancy Gilhooley and now Dr. Kosek. I have been fortunate. He is always very pleasant, and from the moment he walks through the door he puts you at ease and you have his undivided attention.He always speaks in terms I can understand, if I don't understand he will repeat, He has patience, and cares for his patients and there concerns. He never makes me feel rushed.He is always willing to help in any way he can. If I need a referral he always knows who to send me to. I have great confidence in him as my doctor. He truly is the epitome of what a doctor should be! I do recommend him to others.

Bad PCP left the room before I had a chance to ask question.
