My usual PCP is Dr [ ]. He was (of course) booked up when I had a sudden issue, but his office went the extra mile to call around and set up an immediate appointment with Dr. Griesser.

Dr Griesser's assistant, Josh, was very helpful and knowledgeable
August 04, 2022
Dr. Griesser is not my regular doctor but he has been available to me when I've had a couple of issues that needed quick care or follow up. He has been there for me for both short term and longer term health challenges. The last time I went in to see him, he remembered an earlier issue and asked me about it. I was very impressed and appreciative that he is so informed about and caring of his patients, even someone who is not his regular patient. He listens to my feedback, involves me in the decision and is very patient in the process. I really do appreciate his willingness to participate in my health and well-being, and to help me to move forward on an issue that has been plaguing me for about [ ]. I may ask him if he would be willing to be my regular doctor.

Dr. Greisser was outstanding. If I could, I would love to have him as my primary provider, if he was able to take me on. I loved Dr. [ ] who left practice at Asante, and I adored him. I only hope that Dr. [ ] who will take me on as a patient, is as good as Dr. Greisser.

Dr Griesser was excellent. He listened to me, asked pertinent questions and had made a plan of action. He talked with me throughout and explained the procedure. I highly recommend Dr Griesser and the staff at Asante.

The doctor
June 27, 2022
Dr. [ ] is my primary. She was not available so talked with the other doctor. We talked on the phone twice & he called me on Saturday to check. I've not ever seen him in person. However, he is very nice & very attentive to my problems.
February 01, 2022
My husband could not get in to see primary care doctor, so they said he could come in right away for a major swollen right foot. Patient is 78, has leukemia. Dr Griesser ordered x-ray and ultrasound for blood clot. He was swift in ordering those studies and then did follow-up with prednisone which got the swelling in complete control. Followed up with 2nd dose. He returned my calls two times and just had a nice attitude and answers. He called oncology to get answers for treatment. He seemed to really care about the outcome. He just made the whole situation better and without any stress. He is a great doctor, and I would recommend him to anyone who had to see a doctor when theirs was not available. We wish Urgent Care was still there. It was a great place to come when you needed to see a doctor quick. I believe Dr Griesser was one of those doctors:) Thank you! [NAME] [DATE]

Dr. Griesser was fantastic. Knowledgable, caring and patient.
January 19, 2022
Dr. Griesser was very professional and informed about the ear problem I was having. It was my first appt. with him and I left feeling like I had met with a real professional. I very much appreciate his partner in practice, Dr. [ ], and I am happy that Asante was able to find someone with Dr. Griesser's ability and enjoyment in his work to help Dr. [ ]'s busy practice. Another pro in Dr. [ ]'s office is Jennifer (Sorry, I don't know her surname) is always very knowledgeable about my hehealth particulars and ready to go the extra mile to help with my health needs. I hope she will be able to survive her new working situation because if she doesn't. both I and my spouse, also a patient, will miss her deeply, as will, I'm sure, Drs. [ ] and Griesser.
