Info
Masks are optional unless a patient is symptomatic or has been exposed to COVID in the past ten days. While we encourage our patients to obtain COVID vaccinations, we acknowledge there are patients who have chosen to not receive the vaccination at this time. As a result, we are asking our patients to help us in these unprecedented times. If you have tested positive for COVID or been in direct contact with anyone who has tested positive for COVID within the past 10 days, please inform our office staff prior to coming into the office for your appointment. If you have been experiencing fatigue, a cough or fever of any kind, please inform us prior to coming into the office. We will do our best to evaluate you over the phone to determine if it is appropriate to postpone your appointment for a few weeks. Your cardiac care is paramount and we will be available to you by phone or in the office. If you have any questions, please contact the office at (573) 756-1813.
