★★★★★

The office visit with Dr John Granquist was professional, informative, and reassuring. I need to accept that if I am hospitalized, I will not see him. I am a bit old school so that hurts. All that acknowledged, I highly recommend Dr Granquist for office visits and accurate, efficient medical care! He is personable, highly educated, responsive, efficient and gives effective, sensible, doable treatment!

A very professional experience. Dr. Granquist is very attentive and explained everything to me. I am very comfortable in talking with and listening to Dr. Granquist.. who again explains everything very clearly. He is the best, and I am very lucky to have him as my Cardiologist. Also, kudos to the whole staff that I interfaced with, at my office visit. Highly recommended!

First time needing a cardiologist. Highly recommended, so I chose this office. Awesome, friendly staff. Down to earth explanations of how my life in their "family" would go. Lauren G with the prelims was an exact fit since we have the same personality. Dr G listened before he even talked about my situation and what we'd be doing moving forward. Great experience. And by the way, perfectly on time. No waiting!
