From the ease of making an appointment to the actual appointment everything was great. I was seen on time and all facets of my visit were explained clearly to me. Test results were clearly reviewed and all questions answered. He made me feel very comfortable throughout my visit. I will look forward to seeing him for my annual followup.

Originally saw Dr Granquist last year on referral from my PCP, for oirregular heartbeat and high bp. He did a battery of tests, made recommendations, everything worked out well. Most recent visit was a follow up. I’ve found the entire staff, from the office to assistants and technicians to be friendly, helpful, and best of all, prompt!

Start to finish it was an excellent visit. Pre appointment information and check-in was efficient and patient friendly. Dr Granquist and his nurse were pleasant, and explained and questioned me in an appropriate and timely manner. Dr Granquiet was thorough and made the explanation of my condition and plan easy to understand. He is an excellent and patient listener. Choose Dr Granquist for your cardiac care. He’s an outstanding physician.
