Patient Reviews for Gregory D. Johnsen, M.D.
Great doctor. Very clear and showed concern for my health.
I have been dealing with symptoms that I felt were heart issues. Dr Johnson has ordered a heart cath. I appreciate him listening and being willing to make sure I have no blockages.
I had a very good discussion with my dr about a specific issue I was concerned about
Dr. Johnsen was very informative.
They ordered tests so I feel reassured that my concerns were taken seriously
Dr. Johnsen has provided the most effective methods, actually has saved my life twice, in the past 20+ years. Dr. Johnson is the consumate medical professional.
Very good
Excelkent
All of my appointments and meetings with all the people at Oklahoma heart have always been 100% professional and enjoyable experience to go through. I want to thank all of the nurses that take care of me every time I go in they make you feel special and you’re always glad to go back.
Dr. Johnsen listened to my questions and answered them so that I could understand them. Dr. Johnsen is a great doctor and a good friend.
Very informative, explained answers to my questions well, scheduled labs that I am concerned with.
They answered my questions and listened to me. They were very helpful
Dr. Johnsen listened better and seemed to understand my situation better than any. I left feeling he knew what was going on and would do what could be done to help. Good feeling!
Dr. Johnson was prompt, professional and communicated clearly. He was very friendly and easy to talk to. He made me feel very comfortable there and listened to my concerns.
It appeared Dr. Johnson reviewed my chart and referral from Cherokee Nation before seeing me, which I appreciate. When a care provider waits to look over my chart, referral and/or reason I am there until they see me, it’s takes up times needed for my visit. I have been a patient of Dr. Johnson for a long time and appreciate his care and concern very much. I don’t look forward to him retiring.
I had several questions, and Dr.Johnsen answered them thoroughly.
My provider is always there for me and I believe we communicate very well with each other.
Dr. Johnsen is an excellent doctor!
I think the best thing is he knew our chart from the past and asked us questions with that history in mind. It really made me feel like he care about mom and I and that he was actually present and helpful unlike so many drs of today. I have to tell them the same thing over and over so now its just a habit plus he was trying to read the chart in front of us paying attention to the ipad he was totally focused on us! That was very nice. I know its unusual because I felt it when I was there I waslike wow we found our dr!
