Dr Grandquist is sincere, and outgoing, as is his staff. He welcomes my numerous questions regarding my related heart issues, and answers them in a sincere honest manner. I trust his advice emphatically, and highly recommend him to anyone looking for a skilled cardiologist.

Dr Grandquist is a wonderfull doctor. I am blessed to have him for my cardiologist. He is caring of all your needs, takes his time with you, and always answers all your concerns. I also am very please with his entire staff. Their professionalism and courtesy is unmatched. I first met Dr Grandquist 7 years ago as he became my Mom's cardiologist. After meeting him, I made sure to make him mine as well.

Dr Granguist was very engaging from the time he entered the room. He was knowledgeable, asked good questions, listened intently, and took good notes. I appreciated how thorough he was. He recommended next steps, but let me make the final decision on how I wanted to proceed. Additionally, the office staff reflected the same level of care that Dr G demonstrated. They seemed happy to be there which reflects the positive way they are treated.

My appointment was both a very pleasant and very professional experience. Dr. Granquist provided me with a succint explanation of the results of my EKG and also made a hands on exam himself, listening to my heart & lungs Fortunately all was well. Follow up in 6 months

Dr. Granquist takes the time to listen and answer all questions that you may have. He explains all test results and is very good about putting things in prospective. I am confident in his opinion and highly recommend him. I have often messaged him on the portal and he always responds very quickly. Other physicians should follow his example.
