September 8, 2019 7:00 PM

September 3, 2019 was not a good day for the EPIC software system at Good Samaritan Hospital. I was delayed 90 minutes past the appointment time in getting to see Dr. Fenner. Both Dr. Fenner and his nurse apologized for the extreme delay - they said it was due to the poor performance and intermittent availability of the EPIC software so that they could not enter data from their previous patients that morning. Luckily I did not have a busy schedule that morning and wanted to see Dr. Fenner for my semi-annual visit so I stayed during the delay. BUT I WAS ANNOYED as I sat in the waiting room. There was no mention to any of us patients in the waiting room that there was a delay related to the poor performance of the EPIC hospital software. While in the waiting room, I closed my eyes and put my head back on the head rest part of the time while I waited. When my turn came, Dr. Fenner was courteous and attentive during my visit. I am pleased to be one of his patients and I have confidence in him.

August 30, 2019 7:00 PM

Dr. Fenner is wonderful. He always takes time to talk about my whole wellbeing.

August 23, 2019 7:00 PM

July 14, 2019 7:00 PM

July 12, 2019 7:00 PM

Dr Fenner is very focused on providing me with the best decisions about my hearth condition.

July 10, 2019 7:00 PM

We had an excellent conversation about my heart and how it is doing. Dr. Fenner has done a great keeping it in running order since I first saw him several years ago.

June 24, 2019 7:00 PM

Good visit. Spoke at length about diet and exercise. Two topics I was greatly concerned about.

June 23, 2019 7:00 PM

I'm very much thankful to my cardiac doctor Dr.Patric Fenner MD for the excellent care received during my every visit. This time he has suggested some blood work. Which results have been sent by ACL to the doctor. He advised me to come for next visit in June 2020 with some blood report, With a advise to come at any time when you feel uncomfort.

May 21, 2019 7:00 PM

You conversion to new software due to merger with Aurora has created some chaos - had to rescan all my cards - bad date migration in you part & receptionist couldn't get scanner to work for several tries. Then the dr. was delayed due to issues w/your system with patient before me resulting in delays in my appointment.

November 28, 2018 6:00 PM

this provider left the hospital where I originally met him. could not find another doctor I liked at this hospital, so I drive further just to have him as my cardiologist. I feel he is a very concerned doctor and wants what is best for his patients. he's personable, friendly and even knows how to laugh. he can never retire!!!
