There has never been a problem or complaint on my part. If I have a question I’ve always been listened to and never felt rushed. I am very very happy with my caregiver.

My primary care is Katherine Thyssen and I've had her as my primary care for about the past two years. She is top of the line and keeps so current in her medical knowledge and all of that is so appreciated. Thank you.

New location for Renown/ Kaiser. There was a little wait in reception room as the only receptionist seemed overloaded with phone calls. She was very nice and knowledgeable with lots of experience. No problem, I’m not complaining.

Dr. Thyssen and her colleagues are most attentive. Since November 2024, my bride and I have had significant medical issues and Dr. Thyssen and all the medical professionals are exceptional in their interaction with us. We are most pleased with Renown and Sr. Care Plus.

My appointment, allotted time, has gone from 45 minutes with my doctor to 15 minutes with Kaiser Permanente. Sounds like a damn German beauty parlor, which is what I think of them. 15 minutes is what they cut me down to after years of 45 minutes. How do you suppose I feel?

My care provider is Excellent.
The facility has front desk staffing problems.
I came and was in a line of 4 while the only receptionist was taking care of a patient checking in and asking dozens of questions about Kaiser.
One day I arrived 15 minutes before my appointment and the doors were locked and nobody around.

This is a teachable moment. I am always grateful for Dr. Thyssen's care. I just wanted to say that she asked if I wanted to have a ear lavage and I think because of the ear lavage I developed severe vertigo the next day and I'm still experiencing vertigo. So I think as a teachable moment either the doctor or the nurse administering the ear lavage should tell the patient whether they should have this, that the risks involved can be vertigo because I would not have chosen to do it because I missed out on a tennis tournament that I had signed up for this week because I was too busy to play any kind of sports. So that's what I was, that's the only information I'd like to give at this time. Thank you.
