Appointment timing was good. Nurse who took information and blood pressure, weight, and ekg was very nice. Dr. Was excellent, easy to talk to, informative about what I needed to get done and go from there.

I've been with Dr. Grammes for several years now. For the past few, he has been keeping track of a problem shown by my EKG and this time he strongly suggested I need a pacemaker. It only took three days to get testing done and have the procedure. I am extremely impressed by him.

I would not recommend Dr. Grammes due to his lack of Ability to provide the appropriate standard of care to my 85 year old Aunt who passed away under his care. Dr. Grammes may need additional training regarding protocols and procedures. In my opinion he did not provide the appropriate care.
