There is no publicly available rating for this care provider for one or more of the following reasons:
  1. He or she does not see patients in the outpatient clinic setting.
  2. He or she sees patients, but has not yet received the minimum number of Patient Satisfaction Reviews. To be eligible for display, we require a minimum of 30 surveys. This ensures that the rating is accurate and statistically reliable.
  3. He or she is a community provider, not a Geisinger-employed provider. Community providers tend to see patients in their own private outpatient practices, which we do not survey.

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.

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.

Due to the difficulty of accessing the Kingston Clinic by phone, and the lack of adequate staffing, I would not recommend it to anyone. This is in no way a reflection of the care that Dr. Kosek provides; I am pleased with him as a doctor.

Would recommend Dr, but trying to see your Dr, not so good. They need to stop taking new patients, they can't handle it
June 4, 2015
My first time meeting Dr. Kosek. He immediately recognized my issue. Had me call family members and I was sent via ambulance to hospital. This has put me in a position to get continued care for my issue.
June 3, 2015
dr spent time talking about a medication prescribed at office visit but never sent it to local pharmacy. instead, sent it to mail order. also I reviewed with her my mail order for a recurring daily prescription that needed, per the mail order pharmacy, specific written instruction brand specific and be faxed to the mail order. did not happen. I had to take time off again from work the next day to get this resolved.

I'm so glad Dr. Kosek is in the office more. He really listens to what I tell him, and makes sure to tell me to call or e-mail if there's a problem. Also gets me involved to help myself.

We are still early in our trust building because I have only been with him a few months, but his compassion and care and understanding is remarkable, I am sure I will become more confident as I continue to see him. He helped me out through some emotional difficulties. Very helpful.
